In this blog, we will see the definition of relational operators, types of relational operators, and a detailed explanation of each; if you hadn’t checked the previous blog on operators so, check now and add some precious knowledge to the library of your smart brain. Let’s go

What is the relational operator in c++?

A relational operator checks the relationship between two operands—for example, less than, greater than, equal to, etc. 

Types of relational operators

It is subdivided into six parts.

1. Equal to operator ‘==’ 
2. Not equal to operator ‘!=’
3. Greater than operator ‘>’
4. Less than operator ‘<‘
5. Greater than or equal to operator ‘>=’
6. Less than or equal to operator ‘<=’

The following table briefly introduces the types of relational operators.

Operator	Meaning	Example
==	Is Equal to	5 == 10 gives us false
!=	Is not equal to	5 != 10 gives us true
>	is greater than	5 > 10 gives us false
<	is less than	5 < 10 gives us true
<=	is greater than or equal to	5 >= 10 give us false
>=	is less than or equal to	5 <= 10 gives us true

Let’s see them one by one.

1. Equal to operator

The equal to operator(==) checks whether the two given operands are equal or not. It returns

• true – if both the operands are equal or the same
• false – if the operands are unequal

example

#include <iostream>
using namespace std;

int main()
{
    int a = 5;
    int b = 10;
    int c = 10;

    cout << (a == b) << endl;
    cout << (b == c) << endl;

    return 0;
}

output

0
1

In the above output, as you know, 0 is false, and 1 is true in terms of programming.

2. Not equal to operator

The not equal to operator(!=) checks whether the two given operands are equal or not. It returns

• true – if both the operands are unequal 
• false – if the operands are equal

example

#include <iostream>
using namespace std;

int main()
{
    int a = 5;
    int b = 10;
    int c = 10;

    cout << (a != b) << endl;
    cout << (b != c) << endl;

    return 0;
}

output

1   
0 

In the above output, as you know, 0 is false, and 1 is true in terms of programming.

3. Greater than operator

The greater than operator (>) checks whether the left operand is greater than the right operand or not. It returns

• true – if the left operand is greater than the right
• false – if the left operand is less than the right

example

#include <iostream>
using namespace std;

int main()
{
    int a = 5;
    int b = 10;
    int c = 7;

    cout << (a > b) << endl;
    cout << (b > c) << endl;

    return 0;
}

output

0
1

In the above output, as you know, 0 is false, and 1 is true in terms of programming.

4. Less than operator

The greater than operator (<) checks whether the left operand is less than the right operand or not. It returns

• true – if the left operand is less than the right
• false – if the left operand is greater than the right

example

#include <iostream>
using namespace std;

int main()
{
    int a = 5;
    int b = 10;
    int c = 20;

    cout << (a < b) << endl;
    cout << (b < c) << endl;

    return 0;
}

output

1
0

5. Greater than or equal to operator

The greater than or equal to operator ( >= ) checks whether the left operand is greater or equal to the right operand or not. It returns

• true – if the left operand is either greater than or equal to the right
• false – if the left operand is less than the right

example

#include <iostream>
using namespace std;

int main()
{
    int a = 5;
    int b = 10;
    int c = 20;
    int d = 20;

    cout << (a >= b) << endl;
    cout << (b >= c) << endl;
    cout << (c >= b) << endl;
    cout << (c >= d) << endl;

    return 0;
}

output

0
0
1
1

6. Less than or equal to operator

The less than or equal to operator ( <= ) checks whether the left operand is less or equal to the right operand or not. It returns

• true – if the left operand is either less than or equal to the right
• false – if the left operand is greater than the right

example

#include <iostream>
using namespace std;

int main()
{
    int a = 5;
    int b = 10;
    int c = 20;
    int d = 20;

    cout << (a <= b) << endl;
    cout << (b <= c) << endl;
    cout << (c <= b) << endl;
    cout << (c <= d) << endl;

    return 0;
}

output

1
1
