Basics to Code
“In this section, we will explore all the essential topics related to coding, with a special focus on how they contribute to building a strong foundation in the C programming language.
- We will also understand how these concepts are applied in real-world programming scenarios.”
- Keywords and Identifiers
- Tokens in C Programming
- Variables in C Programming

Operators in C Programming
Here we will learn about all the important topics relating to Operators and how these are important for a thorough understanding of the C Programming domain.
- Operators in C are categorized into different types such as arithmetic (+, -, *), relational (==, !=), logical (&&, ||), and bitwise (&, |, ^) to perform specific operations in code.

Storage Classes in C
Storage classes in C define the scope, lifetime, and visibility of variables within a program.
- They help the compiler understand how to manage memory for a variable and where it can be accessed from.


Conditional statements and Decision Making in C
Here we will learn about all the important topics relating to coding and how these are important for a thorough understanding of the C Programming domain.
DataType & Functions in C
Datatypes in C define the kind of data a variable can store, like int, float, or char. Functions are reusable blocks of code that perform specific tasks, making programs more organized and efficient.
- Datatypes define the nature of data (e.g., int, float, char), while functions encapsulate logic into reusable blocks, enabling cleaner and more manageable C programs.


Arrays, String, Structure, Union and Enum In C
Here we will learn about all the important topics relating to coding and how these are important for a thorough understanding of the C Programming domain.
- Arrays in C Programming
- 1D Array in C
- 2D Array in C
- Multi-dimensional arrays
- Passing array as a parameter
- Strings in C Programming
- Array v/s string
- Program for Reversing a String
- Program for Reversing an array
- Enums in C Programming
- Structure in C
- Structure function in C
- Structure pointer in C
- Union in C Programming Programming
- Operation on struct variable
Pointer in C Programming
Pointers in C store the address of other variables, allowing direct memory access and efficient data handling.
- Pointers help manage memory and access data quickly in C programs.
