2.2 第一个C++程序

让我们从经典的”Hello, World!”开始：

#include <iostream>

int main() {
    std::cout << "Hello, World!" << std::endl;
    return 0;
}

编译和运行：

g++ -o hello hello.cpp
./hello

3. 基础语法

3.1 变量和数据类型

#include <iostream>
#include <string>

int main() {
    // 基本数据类型
    int age = 25;                    // 整数
    double height = 175.5;           // 双精度浮点数
    float weight = 70.5f;            // 单精度浮点数
    char grade = 'A';                // 字符
    bool isStudent = true;           // 布尔值
    std::string name = "张三";        // 字符串

    // 自动类型推断（C++11）
    auto score = 95.5;               // 自动推断为double
    auto level = 5;                  // 自动推断为int

    // 输出变量
    std::cout << "姓名: " << name << std::endl;
    std::cout << "年龄: " << age << std::endl;
    std::cout << "身高: " << height << "cm" << std::endl;

    return 0;
}

3.2 常量

#include <iostream>

int main() {
    // const关键字定义常量
    const double PI = 3.14159;
    const int MAX_STUDENTS = 100;

    // constexpr（C++11）编译时常量
    constexpr int SECONDS_PER_MINUTE = 60;

    std::cout << "圆周率: " << PI << std::endl;
    std::cout << "每分钟秒数: " << SECONDS_PER_MINUTE << std::endl;

    return 0;
}

4. 运算符

4.1 算术运算符

#include <iostream>

int main() {
    int a = 10, b = 3;

    std::cout << "加法: " << a + b << std::endl;      // 13
    std::cout << "减法: " << a - b << std::endl;      // 7
    std::cout << "乘法: " << a * b << std::endl;      // 30
    std::cout << "除法: " << a / b << std::endl;      // 3（整数除法）
    std::cout << "取余: " << a % b << std::endl;      // 1

    // 浮点数除法
    double c = 10.0, d = 3.0;
    std::cout << "浮点除法: " << c / d << std::endl;  // 3.33333

    return 0;
}

4.2 比较和逻辑运算符

#include <iostream>

int main() {
    int score = 85;

    // 比较运算符
    std::cout << "score > 60: " << (score > 60) << std::endl;     // true (1)
    std::cout << "score == 85: " << (score == 85) << std::endl;   // true (1)
    std::cout << "score != 90: " << (score != 90) << std::endl;   // true (1)

    // 逻辑运算符
    bool isPass = score >= 60;
    bool isExcellent = score >= 90;

    std::cout << "及格且优秀: " << (isPass && isExcellent) << std::endl;  // false (0)
    std::cout << "及格或优秀: " << (isPass || isExcellent) << std::endl;   // true (1)
    std::cout << "不是优秀: " << (!isExcellent) << std::endl;               // true (1)

    return 0;
}

5. 控制流程

5.1 条件语句

#include <iostream>

int main() {
    int score;
    std::cout << "请输入成绩: ";
    std::cin >> score;

    if (score >= 90) {
        std::cout << "优秀!" << std::endl;
    } else if (score >= 80) {
        std::cout << "良好!" << std::endl;
    } else if (score >= 60) {
        std::cout << "及格!" << std::endl;
    } else {
        std::cout << "不及格!" << std::endl;
    }

    // 三元运算符
    std::string result = (score >= 60) ? "通过" : "不通过";
    std::cout << "考试结果: " << result << std::endl;

    return 0;
}

5.2 循环语句

#include <iostream>

int main() {
    // for循环
    std::cout << "for循环输出1-5:" << std::endl;
    for (int i = 1; i <= 5; i++) {
        std::cout << i << " ";
    }
    std::cout << std::endl;

    // while循环
    std::cout << "while循环倒计时:" << std::endl;
    int count = 5;
    while (count > 0) {
        std::cout << count << " ";
        count--;
    }
    std::cout << "发射!" << std::endl;

    // do-while循环
    std::cout << "do-while循环示例:" << std::endl;
    int number;
    do {
        std::cout << "请输入一个正数(输入0退出): ";
        std::cin >> number;
    } while (number != 0);

    // 范围for循环（C++11）
    std::cout << "范围for循环:" << std::endl;
    int numbers[] = {1, 2, 3, 4, 5};
    for (int num : numbers) {
        std::cout << num << " ";
    }
    std::cout << std::endl;

    return 0;
}

6. 函数

6.1 基础函数

#include <iostream>
#include <string>

// 函数声明
int add(int a, int b);
double calculateAverage(double arr[], int size);
void printMessage(const std::string& message);

int main() {
    // 调用函数
    int result = add(10, 20);
    std::cout << "10 + 20 = " << result << std::endl;

    double scores[] = {85.5, 90.0, 78.5, 92.0};
    double avg = calculateAverage(scores, 4);
    std::cout << "平均分: " << avg << std::endl;

    printMessage("学习C++很有趣!");

    return 0;
}

// 函数定义
int add(int a, int b) {
    return a + b;
}

double calculateAverage(double arr[], int size) {
    double sum = 0.0;
    for (int i = 0; i < size; i++) {
        sum += arr[i];
    }
    return sum / size;
}

void printMessage(const std::string& message) {
    std::cout << "消息: " << message << std::endl;
}

6.2 函数重载

#include <iostream>

// 函数重载 - 相同函数名，不同参数
int multiply(int a, int b) {
    std::cout << "调用int版本" << std::endl;
    return a * b;
}

double multiply(double a, double b) {
    std::cout << "调用double版本" << std::endl;
    return a * b;
}

int multiply(int a, int b, int c) {
    std::cout << "调用三参数版本" << std::endl;
    return a * b * c;
}

int main() {
    std::cout << "5 * 3 = " << multiply(5, 3) << std::endl;
    std::cout << "2.5 * 4.0 = " << multiply(2.5, 4.0) << std::endl;
    std::cout << "2 * 3 * 4 = " << multiply(2, 3, 4) << std::endl;

    return 0;
}

7. 数组和字符串

7.1 数组操作

#include <iostream>
#include <array>

int main() {
    // 传统数组
    int scores[5] = {85, 90, 78, 92, 88};

    // 访问数组元素
    std::cout << "第一个成绩: " << scores[0] << std::endl;
    std::cout << "第三个成绩: " << scores[2] << std::endl;

    // 遍历数组
    std::cout << "所有成绩: ";
    for (int i = 0; i < 5; i++) {
        std::cout << scores[i] << " ";
    }
    std::cout << std::endl;

    // 现代C++数组（C++11）
    std::array<int, 5> modernScores = {85, 90, 78, 92, 88};

    // 范围for循环遍历
    std::cout << "现代遍历方式: ";
    for (int score : modernScores) {
        std::cout << score << " ";
    }
    std::cout << std::endl;

    return 0;
}

7.2 字符串操作

#include <iostream>
#include <string>
#include <vector>

int main() {
    // 字符串创建和初始化
    std::string name = "张三";
    std::string greeting = "Hello, " + name + "!";

    std::cout << greeting << std::endl;

    // 字符串属性
    std::cout << "字符串长度: " << greeting.length() << std::endl;
    std::cout << "字符串大小: " << greeting.size() << std::endl;

    // 字符串操作
    std::string text = "C++编程很有趣";
    std::cout << "原字符串: " << text << std::endl;

    // 查找子串
    size_t pos = text.find("编程");
    if (pos != std::string::npos) {
        std::cout << "找到'编程'在位置: " << pos << std::endl;
    }

    // 替换
    text.replace(pos, 4, "开发");
    std::cout << "替换后: " << text << std::endl;

    // 字符串分割（简单示例）
    std::string data = "苹果,香蕉,橙子";
    std::vector<std::string> fruits;
    size_t start = 0;
    size_t end = data.find(',');

    while (end != std::string::npos) {
        fruits.push_back(data.substr(start, end - start));
        start = end + 1;
        end = data.find(',', start);
    }
    fruits.push_back(data.substr(start));

    std::cout << "水果列表: ";
    for (const std::string& fruit : fruits) {
        std::cout << fruit << " ";
    }
    std::cout << std::endl;

    return 0;
}

8. 指针和引用

8.1 指针基础

#include <iostream>

int main() {
    int number = 42;
    int* ptr = &number;  // ptr指向number的地址

    std::cout << "变量值: " << number << std::endl;
    std::cout << "变量地址: " << &number << std::endl;
    std::cout << "指针存储的地址: " << ptr << std::endl;
    std::cout << "通过指针访问值: " << *ptr << std::endl;
    std::cout << "指针本身的地址: " << &ptr << std::endl;

    // 通过指针修改值
    *ptr = 100;
    std::cout << "修改后number的值: " << number << std::endl;

    // 空指针
    int* nullPtr = nullptr;
    if (nullPtr == nullptr) {
        std::cout << "这是一个空指针" << std::endl;
    }

    return 0;
}

8.2 引用

#include <iostream>

// 使用引用作为参数
void swapValues(int& a, int& b) {
    int temp = a;
    a = b;
    b = temp;
}

// 返回引用
int& getMax(int& a, int& b) {
    return (a > b) ? a : b;
}

int main() {
    int x = 10, y = 20;

    std::cout << "交换前: x = " << x << ", y = " << y << std::endl;
    swapValues(x, y);
    std::cout << "交换后: x = " << x << ", y = " << y << std::endl;

    // 引用示例
    int num = 50;
    int& ref = num;  // ref是num的别名

    ref = 60;  // 修改ref就是修改num
    std::cout << "num = " << num << ", ref = " << ref << std::endl;

    // 返回引用示例
    getMax(x, y) = 100;  // 将较大的值设为100
    std::cout << "操作后: x = " << x << ", y = " << y << std::endl;

    return 0;
}

9. 面向对象编程

9.1 类和对象

#include <iostream>
#include <string>

class Student {
private:
    std::string name;
    int age;
    double score;

public:
    // 构造函数
    Student(const std::string& n, int a, double s)
        : name(n), age(a), score(s) {
        std::cout << "创建学生对象: " << name << std::endl;
    }

    // 默认构造函数
    Student() : name("未知"), age(0), score(0.0) {}

    // 析构函数
    ~Student() {
        std::cout << "销毁学生对象: " << name << std::endl;
    }

    // 成员函数
    void displayInfo() const {
        std::cout << "姓名: " << name
                  << ", 年龄: " << age
                  << ", 成绩: " << score << std::endl;
    }

    // Getter和Setter
    std::string getName() const { return name; }
    void setName(const std::string& n) { name = n; }

    int getAge() const { return age; }
    void setAge(int a) { age = a; }

    double getScore() const { return score; }
    void setScore(double s) { score = s; }

    // 静态成员函数
    static std::string getSchoolName() {
        return "示例中学";
    }
};

int main() {
    // 创建对象
    Student student1("张三", 18, 95.5);
    Student student2("李四", 17, 88.0);

    // 访问成员函数
    student1.displayInfo();
    student2.displayInfo();

    // 使用setter修改属性
    student2.setScore(92.5);
    std::cout << "李四修改后的成绩: " << student2.getScore() << std::endl;

    // 静态函数调用
    std::cout << "学校名称: " << Student::getSchoolName() << std::endl;

    return 0;
}

9.2 继承和多态

#include <iostream>
#include <string>
#include <memory>

// 基类
class Shape {
protected:
    std::string color;

public:
    Shape(const std::string& c) : color(c) {}
    virtual ~Shape() {}

    // 虚函数
    virtual double getArea() const = 0;  // 纯虚函数
    virtual void draw() const {
        std::cout << "绘制一个" << color << "的图形" << std::endl;
    }

    std::string getColor() const { return color; }

    Circle(const std::string& c, double r)
        : Shape(c), radius(r) {}

    double getArea() const override {
        return 3.14159 * radius * radius;
    }

    void draw() const override {
        std::cout << "绘制一个" << color << "的圆形，半径: "
                  << radius << std::endl;
    }
};

// 派生类：矩形
class Rectangle : public Shape {
private:
    double width, height;

public:
    Rectangle(const std::string& c, double w, double h)
        : Shape(c), width(w), height(h) {}

    double getArea() const override {
        return width * height;
    }

    void draw() const override {
        std::cout << "绘制一个" << color << "的矩形，宽: "
                  << width << ", 高: " << height << std::endl;
    }
};

int main() {
    // 使用智能指针（现代C++）
    std::unique_ptr<Shape> circle = std::make_unique<Circle>("红色", 5.0);
    std::unique_ptr<Shape> rectangle = std::make_unique<Rectangle>("蓝色", 4.0, 6.0);

    // 多态调用
    circle->draw();
    std::cout << "圆形面积: " << circle->getArea() << std::endl;

    rectangle->draw();
    std::cout << "矩形面积: " << rectangle->getArea() << std::endl;

    return 0;
}

10. 模板编程

// 模板特化
template <>
const char* getMax<const char*>(const char* a, const char* b) {
    return (strcmp(a, b) > 0) ? a : b;
}

int main() {
    // 使用函数模板
    std::cout << "最大值: " << getMax(10, 20) << std::endl;
    std::cout << "最大值: " << getMax(3.14, 2.71) << std::endl;

            int science = std::stoi(student.substr(pos3 + 1));

            double average = (math + english + science) / 3.0;

            std::cout << name << ": 数学=" << math
                      << ", 英语=" << english
                      << ", 科学=" << science
                      << ", 平均分=" << average << std::endl;
        }
    }
}

int main() {
    const std::string filename = "students.txt";
