vc里面建立一个控制台程序,代码如下:
#include<stdio.h>
#include<string.h>
int
main()
{
int
len;
printf("请输入正方形的边长:");
while(scanf("%n",&len)){
printf("正方形的边长为:%d\n",len);
printf("正方形的表面积为:%d\n",len*len);
printf("正方形的体积为:%d\n",len*len*len);
printf("\n请输入正方形的边长:");
}
}
这段代码是计算正方形表面积和体积的,直接用记事本编写的,没有编译过,不知道有没错误,有错误你自己稍微修改下,大致是这样,我手头上没有vc,就不编译了

#include
<stdio.h>
int
main
(void)
{
int
m,n,k;
printf
("输入M的值:\n");
scanf("%d",&m);
printf
("输入N的值:\n");
scanf("%d",&n);
int
k
=
m
/
n;
printf
("%d.%df",k,k) ;
//
一个%d
为K的值,第二个.d%
为小数点后K位
return
0;
}
我也初学者..
应该是这样编程吧.
