How can we implement the function of randomly generating information in C++?

In C++, you can use the rand() function to generate random numbers. Below is a simple example code showing how to generate random numbers.

#include <iostream>
#include <cstdlib>

int main() {
    // 设置随机种子
    srand(time(0));

    // 生成随机数
    int randomNum = rand();

    std::cout << "随机数为：" << randomNum << std::endl;

    return 0;
}

To generate a random number, you can call the rand() function. However, to avoid generating the same random number each time, it is necessary to call the srand(time(0)) function at the beginning of the program to set the random number seed. This way, the random numbers generated each time the program runs will be different.

In addition to generating random numbers, you can also use random numbers to create other types of information, such as random strings, random array elements, etc. By combining the random number generation function with other data types, you can achieve the function of generating random information.
