项目1
代码
`#include <stdio.h>

include <stdlib.h>

include <time.h>

define N 5

int main()
{
int number;
int i;

srand( time(0) ); 

for(i = 0; i < N; ++i) {
    number = rand()%65 + 1;
    printf("20238331%04d\n", number);

}

system("pause");
return 0;

}`
运行结果

为了生成65以内的数字
生成数位正确的学号

项目2
代码
`#include<stdio.h>

include<stdlib.h>

int main(){
char color;
while(1){
scanf("%c",&color);

switch(color){
    case 'r':printf("stop!\n");break;
    case 'g':printf("go go go\n");break;
    case 'y':printf("wait a minute\n");break;    
    default:printf("domething must be wrong...\n");break;    
}
getchar();

}

system("pause");
return 0;

}`
运行结果

项目3
代码
`#include<stdio.h>

include<stdlib.h>

include<time.h>

int main(){
int ld, d;
int i;

srand( time(0));
ld = rand()%31 + 1;

printf("猜猜2024年5月哪一天会是你的幸运日\n开始喽,你有三次机会,猜吧(1~31:");

    for(i = 1;i <= 3;i++){
        scanf("%d",&d);
        if(d < ld){
            printf("你猜的日期早了,你的幸运日还没到呢\n:");
            if(i <= 2){
                printf("\n再猜(1~31):");
            }
        }
        if(d > ld){
            printf("你猜的日期晚了,你的幸运日在前面哦\n");
            if(i <= 2){
                printf("\n再猜(1~31):");
                }    
        }
        if(d == ld){
            printf("\n哇,猜中了");
			system("pause");
            return 0;
        }    
    } 
if(d != ld)
    printf("\n次数用完啦,偷偷告诉你,5月你的幸运日是%d号\n",ld); 


system("pause");
return 0;

}`
运行结果

项目4
代码
`#include<stdio.h>

include<stdlib.h>

double func(int n, int a);
int main()
{
int n, a;
double s;
while(1){
scanf("%d%d",&n,&a);
s=func(n,a);
printf("n = %d,a = %d,s = %lf\n",n,a,s);
}
return 0;
}
double func(int n, int a)
{
int i,b=0;
double s=0.0;
for(i=1;i<=n;i++){
b=b10+a;
s=s+1.0
i/b;
}

system("pause");
return s;

}`
运行结果

项目5
代码
`#include<stdio.h>

include<stdlib.h>

int main(){
int i,j;

for(i=1;i<=9;i++){
    for(j=1;j<=i;j++){
        printf("%d*%d=%-3d",j,i,j*i);
    }
    printf("\n");
}
system("pause");
return 0;

}`
运行结果

项目6
代码
`#include <stdio.h>
