求用c语言编写程序

vc里面建立一个控制台程序，代码如下：
#include
#include
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

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.

//程序可以成功运行，可以写入文件和屏幕，不懂得可以交流！
//希望kutpbpb的回答能对你有所帮助！！！
