Relational / Comparison Operators

What are Relational / Comparison Operators in C++?


Relational operators are used to compare two values or expressions to evaluate the relationship. Following table lists the relational operators in C++.
Operator Action
== Equal to
!= Not equal to
> Greater than
< Less than
>= Greater than or equal to
<= Less than or equal to

Example :

#include <iostream.h>
using namespace std;
int main( )
int a = 20;
int b = 10;
if ( a < b )
cout << " a is less than b" ;
cout << "b is less than a";

Result :

b is less than a

In the above example the relational operator "<" is used to check if a is less than b. Thus comparison between two values or expression can be performed using this operator.
