C语言编程题:怎样逆序输出数字

C++语言环境下代码如下：

#include <iostream.h>
int summy(int x)
{
int a=0;
while(x!=0)
{
a=a*10+x%10;
x=x/10;
}
return a;
}
void main()
{
int x;
cout<<"请输入一个正整数：";
cin>>x;
cout<<x<<"的翻转为"<<summy(x)<<endl;
}

可以输入任意一个N位数，按回车结束

#include<stdio.h> void p(); void main() { p(); putchar('\n'); } void p() { char ch; ch=getchar(); if(ch!='\n') p(); if(ch=='\n') putchar('\n'); else putchar(ch); }

while(num>=0)

{

printf("%d",num%10);

num=num/10;

}

+++++++++++++++++++++++++++++++++++++++++++++++++ You can have a try,maybe my answer useful to you. 如满意，Yadie.23十分感谢您的采纳。*^-^*
