Question

int x=(5+8)/10;
if(x)
cout << "10";
else
cout << "20";

//what should be answer

Answer 1

Declaring an integer variable named x and assigning it a value of (5+8) or 13/10 i.e., 1.

The program takes 1 as true. As the if statement checks the condition and then executes the block of code if the result is true otherwise not if false. So, the first statement results in true giving 10 as the output.

Note : If the condition had been false or 0, then the else statement would be executed and not the if one.
