1.求C语言源代码 题目 学生成绩管理系统
2.学生考试管理系统，线考JAva源代码
3.急求“用c语言做加减乘除考试系统”各位大哥帮帮忙！试系！统源！线考！试系房在线源码
4.现在在做关于 asp的统源vue源码知乎网上考试系统 希望你能帮忙

急求“用c语言做加减乘除考试系统”各位大哥帮帮忙！！线考如何运行php源码！试系！统源
#include<stdio.h>
#include<stdlib.h>
#include<time.h>
main()
{ int i,a,b,c,d,s=0;
srand(time(NULL));
for(i=1;i<=;i++)
{ a=rand()%+;
b=rand()%9+2;
d=rand()%4;
switch(d)
{
case 0: printf("%d+%d=",a,b);
scanf("%d",&c);
if (a+b==c)
{ s+=;
printf("right!\n");
}
else printf("error!\n");
break;
case 1: printf("%d-%d=",a,b);
scanf("%d",&c);
if (a-b==c)
{ s+=;
printf("right!\n");
}
else printf("error!\n");
break;
case 2: printf("%d*%d=",a,b);
scanf("%d",&c);
if (a*b==c)
{ s+=;
printf("right!\n");
}
else printf("error!\n");
break;
case 3: printf("%d/%d=",a,b);
scanf("%d",&c);
if (a/b==c)
{ s+=;
printf("right!\n");
}
else printf("error!\n");
break;
}
}
printf("\n\nscore=%d\n",s);
getch();
}
本程序在dev-c++中通过编译。如果你觉得有必要的网络传销系统源码话，可以把里面的right、wrong和score分别改成正确、错误、和得分。c语言人工源码
还有什么不清楚的问题的话，可以给我留言，我看到后会尽快回复的。
现在在做关于 asp的网上考试系统 希望你能帮忙
首先建立一数据库exercise.mdb，其中包括两个表：user和test，user表中有包括三个字段：
字段名称：user；字段类型：文本；字段大小：。存储用户名
字段名称：passwd；字段类型：文本；字段大小：。存储用户密码
字段名称：score；字段类型：数字；字段大小：整型。存储用户成绩
test表中有五个字段：
字段名称：question；字段类型：文本；字段大小：。存储考试题目
字段名称：a；字段类型：文本；字段大小：。存储选项A的答案
字段名称：b；字段类型：文本；字段大小：。存储选项B的答案
字段名称：c；字段类型：文本；字段大小：。存储选项C的答案
字段名称：d；字段类型：文本；字段大小：。存储选项D的答案
字段名称：ans；字段类型：文本；字段大小：2。存储正确答案
