Relational operators in C
The following are the relational operators in C.
> ,<, >=, <=
The relational operators give answer in the form of true or false only.
true is represented by 1, and false by 0. It doesn’t mean that only 1 is true.
Before we discuss the relational operators let us understand the true and false values in C.
True and False in C
In C Programming language, only 0 is false, other than 0 everything is true.
Ex
- “RAM” is True
- 1 is True.
- ‘A’ is True.
- -25 is True.
- 0.25 is True.
- 0 is False.
Relational operators
- 45>23 = 1 (since it is true, and it is represented by 1)
- 45<23 = 0 (since it is false, and it is represented by 0)
- 20>=20 = 1 (since it is true, and it is represented by 1)
- 23<=87 = 0 (since it is false, and it is represented by 0)
