# Relational Operations in a Programming Language

## Overview of Relational Operations

• Relational operations are used in programming languages to compare two values or expressions.
• These operations return a Boolean value (True or False) based on the condition of the comparison.

## The Six Basic Relational Operators

• Equality Operator (==): Checks if the values of two operands are equal or not. If yes, it returns True.
• Not Equal Operator (!=): Checks if the values of two operands are equal or not. If the values are not equal, it returns True.
• Greater than Operator (>): Checks if the value of left operand is greater than the value of right operand. If yes, it returns True.
• Less than Operator (<): Checks if the value of left operand is less than the value of right operand. If yes, it returns True.
• Greater than or equal to Operator (>=): Checks if the value of left operand is greater than or equal to the value of right operand. If yes, it returns True.
• Less than or equal to Operator (<=): Checks if the value of left operand is less than or equal to the value of right operand. If yes, it returns True.

## Application of Relational Operations

• Relational operators are widely used in conditional statements, especially in loops and if statements.
• They are essential for controlling the flow of execution in a program, allowing the program to react differently depending on the input.

## Specific Use Cases in Programming

• Sorting algorithms rely heavily on relational operators to compare elements and decide their order.
• Search algorithms use relational operators to locate a desired piece of data within a larger set.

## Sidenotes

• Because these are Boolean operations, the output is always True or False.
• The values or expressions being compared must be compatible types — for instance, you typically can’t directly compare a string and an integer.
• However, some languages will automatically coerce types where possible, such as Python’s ability to compare integers and floats.
