Question

Exercise 1:
Write down a C program in order to:
 Read two integer values x and y.
 Compute their sum, storing it into an additional variable.
 Display the result of the addition on screen.
Is it possible to solve the same problem without using the additional variable?

Answer 1

yes very possible. i don't know about C language but in C++
that is

#include <iostream>

using std::cout;
using std::cin;
using std::endl;

int main()
{
int x=0,y=0;
int sum=0;
cout<<"please enter two integers :"<<endl;
cin>>x>>y;

sum=x+y;

cout<<"your sum is :"<<sum<<endl;

return 0;
}

Answer 2

x += y;
printf( "%d\n", &x );
