Question

In C++ write an application which takes positive or negative integers and returns the sum of each place in the number, such that 246 results in 12 and -88 results in -16. The program is called and runs with no prompt for input. The program reads exactly one signed integer from standard input. The program displays the sum of each digit of the number as a signed integer. This should be done in two files called main.cc and makefile.The result of calling the make application should be an executable named 01hw .

Answer 1

#include<iostream>
#include<fstream>
using namespace std;

int main()
{
ofstream file;
file.open ("01hw.txt");

int value,sum=0,rem;
cout<<"Enter any value : "<<endl;
cin>>value;
while(value)
{
rem=value%10;
value=value/10;
sum=sum+rem;
}
cout<<"Sum of Digits is "<<sum<<endl;

file << "Sum of Digits is "<<sum;
file.close();
return 0;
}
