A collection of my C programming algorithms, logic building exercises, and academic codes for my B.Tech CSE (AI & DS).

📌 OVERVIEW

This repository tracks my progress while learning the fundamentals of C programming. The examples focus on variables, input and output, arithmetic, conditionals, and basic problem-solving.

📂 SIMPLE ALGORITHMS

All examples are stored in the Simple Algorithms directory. Each program is a standalone C file with its own main function.

File	What it does	Main concepts
absolute.c	Finds the absolute value of an integer.	if-else, unary negation
age_vote.c	Calculates age from a birth year and checks voting eligibility.	Input, arithmetic, conditionals
average.c	Calculates the average of three integers.	Arithmetic operators, integer division
conditional_swap.c	Updates three values conditionally and prints their sum.	Nested conditionals, arithmetic
division.c	Divides two user-provided numbers.	float, input, arithmetic
interest.c	Calculates simple interest.	Formula translation, float
leap_year.c	Checks whether a year is a leap year.	Logical operators, modulo operator
numcheck.c	Identifies whether a number is positive, negative, or zero.	if-else if-else, comparisons
scan_sub.c	Subtracts one user-provided integer from another.	scanf, variables, arithmetic
sum.c	Adds two predefined integers.	Variables, assignment, printf
swap.c	Swaps two integers using a temporary variable.	Assignment, temporary storage
tax.c	Calculates tax and the final price of a product.	Percentages, float, arithmetic
time_convertor.c	Converts days into hours, minutes, and seconds.	Unit conversion, arithmetic

⚙️ HOW TO RUN

You need a C compiler such as GCC. On Windows, MinGW-w64 is a common choice.

Clone the repository and open the examples directory:

git clone https://github.com/im-nitin/C.git
cd "C/Simple Algorithms"

Compile a program and run it. Replace sum with any filename from the table:

gcc sum.c -o sum

On Windows PowerShell:

.\sum.exe

On Linux or macOS:

./sum

Most programs read values from standard input. Follow the prompts after starting the executable.

🧭 LEARNING FOCUS

• C syntax, variables, and data types
• Console input and output with scanf and printf
• Arithmetic and percentage calculations
• Conditional logic and comparison operators
• Translating everyday problems into small algorithms
