KTU BTECH SEMESTER 2 PROGRAMING IN C FREE MARATHON

Introduction

This tutorial provides a comprehensive guide on programming in C, as outlined in the "KTU BTECH SEMESTER 2 PROGRAMMING IN C FREE MARATHON" video. It is designed for BTech students looking to enhance their programming skills and gain a solid foundation in C programming. The steps will cover essential concepts, coding practices, and resources for further learning.

Step 1: Understanding C Programming Basics

• Familiarize yourself with C syntax and structure.
• Key components to learn:
  • Data Types: int, float, char, etc.
  • Variables: Declaration and initialization.
  • Operators: Arithmetic, relational, and logical operators.

Practical Tip: Write simple programs to practice using different data types and operators.

Step 2: Control Structures

• Learn about different control structures that guide the flow of your program:
  • Conditional Statements: if, else if, else, and switch.
  • Loops: for, while, and do-while loops.

Common Pitfall: Ensure proper use of braces {} to avoid logical errors in conditional statements and loops.

Step 3: Functions in C

• Understand the importance of functions for code reuse and organization.
• Key points:
  • Function Declaration: Define a function prototype.
  • Function Definition: Write the body of the function.
  • Function Calling: Learn how to call functions in your main program.

Example Code:

int add(int a, int b) {
    return a + b;
}

Step 4: Arrays and Strings

• Explore how to handle collections of data using arrays and strings.
• Key topics:
  • Declaring Arrays: Syntax for single and multidimensional arrays.
  • String Manipulation: Functions like strlen, strcpy, and strcat.

Practical Tip: Practice manipulating arrays and strings through simple exercises, such as reversing a string or finding the maximum number in an array.

Step 5: Pointers and Memory Management

• Gain a basic understanding of pointers and dynamic memory allocation.
• Important concepts:
  • Pointer Declaration: How to declare and use pointers.
  • Dynamic Memory: Use malloc and free for memory management.

Example Code:

int *ptr;
ptr = (int*)malloc(sizeof(int) * 5);
free(ptr);

Step 6: File Handling

• Learn how to read from and write to files in C.
• Key functions:
  • fopen: Open a file.
  • fprintf: Write to a file.
  • fscanf: Read from a file.
  • fclose: Close a file.

Practical Tip: Create a program that logs user input to a file for practice.

Conclusion

In this tutorial, we covered the foundational aspects of programming in C, including basic syntax, control structures, functions, arrays, pointers, and file handling.
