test 1

#include<stdio.h>
#include<stdlib.h>
#include<time.h>

#define N 5
#define R1 586
#define R2 701

int main()
{
    int number;
    int i;
    
    srand( time(0) );  // 以当前系统时间作为随机种子
    
    for(i = 0; i < N; ++i)
    {
        number = rand() % (R2 - R1 + 1) + R1;
        printf("20228330%04d\n", number);
    }
    return 0;
 } 

问题一：生成一个R1~R2之间的整数

问题二：随机抽取学号，类似随机数字生成器

 

test 2

#include<stdio.h>

    getchar();
    scanf("%c%c%c", &c1, &c2, &c3);
