Hence, if the resultant value of relational expression is “0”, then the expression is “False”. If the resultant value of relational expression is “1”, then the expression is “True”.

Relational Operators:

Relational operators are used to compare numeric and character values using the following operators:

Greater than (>)

Less than (<)

Greater than or equal to (>=)

Less than or equal to (<=)

Equal to (==)

Not equal to (!=)

These operators will determine whether specific relationship exists between two values of same type.

Relational Expression:

Relational operators are “binary”, so it needs two operands for comparison. Consider the following expression using the less-than operator:

A < B

The above expression is called a “relational expression”. It is used to find whether “A” is less than “B”.

Relational expression is also called as “Boolean expression”, because the resultant value of all relational expression is either “True” or “False”. But the states of Boolean values are stored as “0” and “1”.

Hence, if the resultant value of relational expression is “0”, then the expression is “False”. If the resultant value of relational expression is “1”, then the expression is “True”.
