In C++, Relational Operators are useful to check the relation between two operands like we can determine whether two operand values equal or not, etc., based on our requirements.
Generally, the C++ relational operators will return true only when the defined operands relationship becomes true. Otherwise, it will return false.
For example, we have integer variables a = 10, b = 20. If we apply a relational operator >= (a >= b), we will get the result false because the variable “a” contains a value that is less than variable b.
The following table lists the different types of operators available in c++ relational operators.
| Operator | Name | Description | Example (a = 6, b = 3) |
|---|---|---|---|
| == | Equal to | It compares two operands, and it returns true if both are the same. | a == b (false) |
| > | Greater than | It compares whether the left operand greater than the right operand or not and returns true if it is satisfied. | a > b (true) |
| < | Less than | It compares whether the left operand less than the right operand or not and returns true if it is satisfied. | a < b (false) |
| >= | Greater than or Equal to | It compares whether the left operand greater than or equal to the right operand or not and returns true if it is satisfied. | a >= b (true) |
| <= | Less than or Equal to | It compares whether the left operand less than or equal to the right operand or not and returns true if it is satisfied. | a <= b (false) |
| != | Not Equal to | It checks whether two operand values equal or not and return true if values are not equal. | a != b (true) |
C++ Relational Operators Example
Following is the example of using the Relational Operators in c++ programming language.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | #include <iostream> using namespace std; int main() { bool result; int x = 10, y = 20; result = (x == y); cout<<"Equal to Operator: " << result<<endl; result = (x > y); cout<<"Greater than Operator: " << result<<endl; result = (x <= y); cout<<"Lesser than or Equal to: "<< result<<endl; result = (x != y); cout<<"Not Equal to Operator: " << result<<endl; } |
Output:
