C Language Exercises

This collection of hands-on exercises is designed to strengthen C programming skills. Learners can move beyond theory and apply knowledge by solving practical, real-world problems. The challenges cover a wide range of topics, from fundamental syntax and control structures to advanced concepts like pointers, memory management, and file I/O. Each exercise provides an opportunity to write, compile, and debug C code, building confidence and a deeper understanding of the language's core principles. These targeted practice problems help solidify learning and prepare individuals for real-world development scenarios.

Read User Input in C

Read User Input in C

This lab teaches you how to read user input in C using the scanf() function. You'll learn to use different data types like char and int to read and display user input, focusing on name and age as examples. The lab covers essential C programming concepts including variables, data types, user input, and output.

Swapping Numbers with Pointers

Swapping Numbers with Pointers

In C programming, you can swap two numbers using pointers. Pointers are powerful features in C that allow us to manipulate data by storing and accessing addresses instead of actual values. In this lab, we will learn how to swap two numbers using pointers.

Array Traversal Using Pointers

Array Traversal Using Pointers

Pointer arithmetic refers to the addition or subtraction of a pointer by an integer value. Using pointers, we can traverse an array in both forward and backward direction. In this lab, we will learn how to traverse an array using pointers in C language.

Finding Largest and Smallest Array Elements in C

Finding Largest and Smallest Array Elements in C

Finding the largest and smallest element in an array is a common problem in programming. In this lab, you will learn how to write a C program to find the largest and the smallest elements in an array using a step-by-step approach.

Determine Integer or Float in C

Determine Integer or Float in C

In this lab, we will write a C program to check if the input number is an integer or a float. We will be using basic string manipulation techniques to check for the presence of a decimal point in the user input.

Find the Largest Number Among N Numbers

Find the Largest Number Among N Numbers

In this lab, we will learn how to write a C program to find the largest number among n user input numbers. We will use a simple for loop to iterate through all the input numbers and compare each number with a variable 'big' that will store the largest number found so far.

Determine Perfect Square in C

Determine Perfect Square in C

In this lab, you will learn how to check whether a number is a perfect square or not using a C program. A perfect square is a number that is the product of an integer multiplied by itself. For example, 9 is a perfect square because 3 \* 3 = 9. We will write a program that takes user input and checks whether the number is a perfect square or not.

Circle Area and Circumference in C

Circle Area and Circumference in C

In this lab, we will learn how to write a C program to find the area and circumference of a circle. We will use the formula area = PI radius radius and circumference = 2 PI radius. We will be using the stdio.h library to read and write data.
