#include <iostream>
using namespace std;
int sum(int num1,int num2){
    int sum;
	sum = num1 + num2;
	return sum;
	}
int div(int num1,int num2){
    int sum;
	sum = num1 / num2;
	return sum;
	}
int main()
{
char q ='y'; // to quite the programme
int choose;
while(q == 'y'){
  cout <<"Welcome to the super programme"<<endl;
  cout <<"1- finding the sum of the numbers."<<endl;
  cout <<"2- finding the divide of the numbers."<<endl;
  cout <<"please choose which programe you want:"<<endl;
  cin >> choose;
  while(choose < 1 || choose > 2){
  cout<<"please choose ethir '1' or '2'";
  cin >> choose;
  }
  if(choose == 1){
  cout <<"Please enter two numbers:";
  cin >> num1 >> num2;
  sum(num1,num2);
  }else if(choose == 2){
  cout <<"Please enter two numbers:";
  cin >> num1 >> num2;
  div(num1,num2);
  }
  cout <<" ,Repeat?";
  cin >> q;
  }
    return 0;
}


can you show me my problem here?

waiting for you

Now it works.
Compare the two codes to find diferences.

thanks brazyuri86 (3)

so i must to Separate cin>>?

one more question, can i avoid doing this total = sum(num1,num2); ad just do like this sum(num1,num2);

thank again :)

No, because it returns an int, and if you were to just call it, it would have nothing to return to, causing an error. :D
