C Programming Practice

A collection of everything I learned during my lessons on C: small, focused programs that each demonstrate one core concept.

Contents

File	What it covers
Ascii Value of a Character	Finding the ASCII value of a character
append.c	Appending data to an existing file
creatingFiles.c	Creating and writing files with file handling functions
loopingThroughAnArray	Iterating over the elements of an array
maxOfThreeNums.c	Finding the largest of three numbers
struct.c	Defining and using structures
swap.c	Swapping values using a function (pointers)
swappingVariables.c	Swapping two variables directly
reverseNumber.c	Reversing the digits of an integer using a loop, % and /

Topics Practiced

• Variables, data types, and ASCII values
• Conditional logic (comparing numbers)
• Arrays and looping
• Pointers and functions
• Structures (struct)
• File handling (create, write, append)

Getting Started

Prerequisites

A C compiler such as GCC or Clang.

gcc --version

Clone the repository

git clone https://github.com/Anujgiri1279/C.git
cd C

Compile and run a program

gcc swap.c -o swap
./swap

On Windows (MinGW):

gcc swap.c -o swap.exe
swap.exe

Replace swap.c with any other .c file in the repo. For files without a .c extension, rename them to end in .c before compiling, for example:

cp "loopingThroughAnArray" loopingThroughAnArray.c
gcc loopingThroughAnArray.c -o loopingThroughAnArray
./loopingThroughAnArray
