一小段代码纠正

Question

5．输入一个正整数按逆序输出。#include<iostream.h>main(){                         int m,n;cout<<"input m=";cin>>m;if(m<0)m=fabs(m);while(m){ n=m%10;cout<<m;n/=10;}}

Answer 1

#include<iostream>

#include<math.h>

using namespace std;

int main(){

cout<<"input a number"<<endl;

int m;

cin>>m;

int angel;

if(m<0){angel=1;m=fabs(m);}

if(angel==1)cout<<"-";

while(m>0){

int n=m%10;

m=m/10;

cout<<n;

}

return 0;

}
