Relational and Equality Operators: <, <=, >, >=, ==, !=
The binary relational and equality operators compare their first operand to their second operand to test the validity of the specified relationship. The result of a relational expression is 1 if the tested relationship is true and 0 if it is false. The type of the result is int.
Example
In the following example, two integers are tested for inequality:
// Example of the inequality operator
int nNumA=1, nNumB=2;
if (nNumA != nNumB) { // it's true: the operands are not equal
AnyFunction(); // therefore, this function is executed
}
