Relational operators in C programming

Relational Operators in C

Relational operators in C are used to compare two values. They return a boolean result, which is typically used in conditional statements to control the flow of the program. Here’s a guide to the relational operators available in C:

1. Equal to Operator (==)

The == operator checks if two values are equal.

int a = 5;
int b = 10;
if (a == b) {
    printf("a is equal to b");
} else {
    printf("a is not equal to b");
}

2. Not Equal to Operator (!=)

The != operator checks if two values are not equal.

int a = 5;
int b = 10;
if (a != b) {
    printf("a is not equal to b");
} else {
    printf("a is equal to b");
}

3. Greater than Operator (>)

The > operator checks if one value is greater than another.

int a = 5;
int b = 10;
if (a > b) {
    printf("a is greater than b");
} else {
    printf("a is not greater than b");
}

4. Less than Operator (<)

The < operator checks if one value is less than another.

int a = 5;
int b = 10;
if (a < b) {
    printf("a is less than b");
} else {
    printf("a is not less than b");
}

5. Greater than or Equal to Operator (>=)

The >= operator checks if one value is greater than or equal to another.

int a = 5;
int b = 5;
if (a >= b) {
    printf("a is greater than or equal to b");
} else {
    printf("a is less than b");
}

6. Less than or Equal to Operator (<=)

The <= operator checks if one value is less than or equal to another.

int a = 5;
int b = 5;
if (a <= b) {
    printf("a is less than or equal to b");
} else {
    printf("a is greater than b");
}

Relational Operators Summary

Operator	Description	Example	Usage
==	Equal to	a == b	Checks if two values are equal
!=	Not equal to	a != b	Checks if two values are not equal
>	Greater than	a > b	Checks if one value is greater than another
<	Less than	a < b	Checks if one value is less than another
>=	Greater than or equal to	a >= b	Checks if one value is greater than or equal to another
<=	Less than or equal to	a <= b	Checks if one value is less than or equal to another

Note: Relational operators are used in conditional statements such as if and while to control the flow of the program based on comparisons.
