Preface

Randomly generate letters or strings using C/C++ language

#define _CRT_SECURE_NO_WARNINGS //防止系统报函数不安全
#include<stdio.h>
#include<stdlib.h>
#include<time.h>
using namespace std;
int main()
{
    
    
for (int i = 0; i < 100; i++)
{
    
    
ch = 'a' + rand() % 26; //随机生成字母，这里采用对26取余数，得到的余数在0~25之间
}
}

# 总结
虽然随机生成字符串的思想比较简单，但是我们要把理解巧用对26取余数的比较巧妙的思路。
