Operators in C

🎙️ Introduction

Hello everyone!

In the previous chapters, we learned about:

Data

Data Types

Variables

Constants

We learned how to store data.

But storing data alone is not enough...Read More

🔹 Step 1: What is an Operator?

An operator is a symbol that tells the computer to perform a specific operation on data.

In simple words:

👉 Operators perform actions on variables and values.

For example:

performs addition

performs subtraction

performs multiplication

/ performs division

If variables are the data containers, operators are the...Read More

🔹 Step 2: Types of Operators in C

C language provides many types of operators.

They are mainly classified into:

1️⃣ Arithmetic Operators
2️⃣ Relational Operators
3️⃣ Logical Operators
4️⃣ Assignment Operators
5️⃣ Increment and Decrement Operators
6️⃣ Bitwise Operators
7️⃣ Conditional (Ternary) Operator
8️⃣ Special Operators

Let us understand each one clearly...Read More

🔹 Step 3: Arithmetic Operators

Arithmetic operators are used to perform mathematical calculations.

They include:

Addition (+)

Subtraction (-)

Multiplication (*)

Division (/)

Modulus (%)

For example:
If a = 10 and b = 5

Then:

a + b gives 15

a - b gives 5

a * b gives 50

a / b gives 2

a % b gives remainder

These operators are used in calculations, formulas...Read More

🔹 Step 4: Relational Operators

Relational operators are used to compare two values.

They return either true or false.

They include:

== (Equal to)

!= (Not equal to)

(Greater than)

< (Less than)

= (Greater than or equal to)...Read More

🔹 Step 5: Logical Operators

Logical operators are used to combine multiple conditions.

They include:

&& (Logical AND)

|| (Logical OR)

! (Logical NOT)

Example:
If age > 18 AND citizen == true...Read More

🔹 Step 6: Assignment Operators

Assignment operators assign values to variables.

The most basic one is:

= (Assignment operator)

Example:
a = 10

There are also compound assignment operators...Read More

🔹 Step 7: Increment and Decrement Operators

These operators increase or decrease a value by 1.

++ (Increment)

-- (Decrement)

Example:
a++ increases value by 1
a-- decreases value by 1

They are commonly used in loops...Read More

🔹 Step 8: Bitwise Operators

Bitwise operators work on binary numbers (bits).

They include:

& (AND)

| (OR)

^ (XOR)

~ (NOT)

<< (Left shift)

(Right shift)

These are mainly used in...Read More

🔹 Step 9: Conditional (Ternary) Operator

The conditional operator is written as:

? :

It is a short form of if-else.

Example concept:
condition ? value_if_true : value_if_false...Read More

🔹 Step 10: Why Operators Are Important

Operators are important because:

They perform calculations

They make decisions

They control program flow

They modify data

They build logic

Without operators, programming is impossible...Read More

📌 Summary

In this chapter, we learned:

Operators perform actions on data.

C has different types of operators.

Arithmetic operators handle calculations.

Relational operators compare values...Read More
