Question

#include <iostream>;
using namespace std;
int main()
{
int x;
int num;
int numb;
int y;
cin >> num;
cin >> x;
cin >> numb;
if (x = x)
{
y = num - numb;
}
else
(
y = num + numb);
cout << "Answer=" << y << endl;
}

Answer 1

What should be the value of x? if(x=x) is a wrong way to check condition. Use if (x == some_value)
The following code will do subtraction if x is 1, it'll perform addition otherwise.

Sample input:
12 1 4
answer: 8
12 3 4
answer: 16
(note: the 2nd input is x)
