RELATIONAL OPERATORS

 

RELATIONAL OPERATORS

 

Relational operators in C are used to compare the relationship between two operands. They evaluate the conditions and return a Boolean result, which is either true or false. Relational operators are commonly used in conditional statements and loops to make decisions based on comparisons. Here are the relational operators in C:

 

1. Equal to (==): Checks if two operands are equal.

   Example:

   int a = 5;

   int b = 7;

   if (a == b)

 { // This condition is false, so the code inside the if block will not execute.  }

 

2. Not equal to (!=): Checks if two operands are not equal.

   Example:

   int a = 5;

   int b = 7;

   if (a != b)

{   // This condition is true, so the code inside the if block will execute.}

 

3. Greater than (>): Checks if the first operand is greater than the second.

   Example:

   int a = 5;

   int b = 7;

   if (a > b)

 { // This condition is false, so the code inside the if block will not execute }

 

4. Less than (<): Checks if the first operand is less than the second.

   Example:

   int a = 5;

   int b = 7;

   if (a < b)

{  // This condition is true, so the code inside the if block will execute.}

 

5. Greater than or equal to (>=): Checks if the first operand is greater than or equal to the second.

   Example:

   int a = 5;

   int b = 7;

   if (a >= b) {  // This condition is false, so the code inside the if block will not execute. }

 

6. Less than or equal to (<=): Checks if the first operand is less than or equal to the second.

   Example:

   int a = 5;

   int b = 7;

   if (a <= b)

{ // This condition is true, so the code inside the if block will execute.}

 

Relational operators return a value of 1 (true) if the condition is satisfied, and a value of 0 (false) otherwise. These operators can be used with variables, constants, or expressions to compare values and make logical decisions in your C programs.
