新手请教编程题(例如:输入1234,便输出1 2 3 4)
编写一个程序,提示用户输入整数,然后输出该数的每位数字和这些数字之和.例如输入1234或者-1234,都输出1 2 3 4.我只会到输出4 3 2 1
#include <iostream>
using namespace std;
int main()
{
int num;
int sum=0;
cout<<"Please input a ineger "<<endl;
cin>>num;
if(num<0)
num=-num;
while(num!=0)
{
sum=sum+num%10;
cout<<num%10<<" ";
num=num/10;
}
cout<<endl;
cout<<"the sum is "<<sum<<endl;
return 0;
}
