if (x==(x-x+x)) { cout <<" Equal "; } else { cout <<" Not Equal "; }

Question

A. Equal
B. Not Equal
C. Error
D. None

Answer 1

Equal

Always add a value to "x" to understand the code better:

Example (C++):

if (1==(1-1+1))
{
cout <<" Equal ";
} else
{
cout <<" Not Equal ";
}

//First solve those in parenthesis
// 1 - 1 = 0
// 0 + 1 = 1
// 1 == 1 is true

Answer 2

i prints equal.because it satisfies if condition
