在C++中生成随机数学运算符

#include <cstdlib>
#include <ctime>

int main() {
    srand(time(0)); // 设置随机数种子为当前时间
    // ...
    return 0;
}

#include <cstdlib>
#include <ctime>
#include <iostream>

int main() {
    srand(time(0)); // 设置随机数种子为当前时间

    int randomOperator = rand() % 4; // 生成范围在 0 到 3 之间的随机数

    char operatorChar;
    switch (randomOperator) {
        case 0:
            operatorChar = '+';
            break;
        case 1:
            operatorChar = '-';
            break;
        case 2:
            operatorChar = '*';
            break;
        case 3:
            operatorChar = '/';
            break;
    }

    std::cout << "随机生成的运算符是：" << operatorChar << std::endl;

    return 0;
}
