C Programming Labs: Dynamic Memory, Pointers & Global Variables for Data Analysis

Embark on a foundational journey into the world of C programming, the bedrock of countless software systems. This structured learning path is meticulously crafted for beginners, offering a systematic roadmap to master the C language. Dive deep into core concepts like efficient memory management, the intricacies of pointers, and essential system-level programming. Forget passive learning; our interactive C language playground provides hands-on, non-video exercises that empower you to write robust and efficient C programs from day one. Let's explore some key labs that will sharpen your C skills and build a strong programming foundation.

Dynamic Memory Allocation in C Programming

Dynamic Memory Allocation in C Programming

Difficulty: Beginner | Time: 30 minutes

In C programming, we may not always know the initial size of an array beforehand. In such cases, we use dynamic memory allocationβ€”a method of allocating memory only when necessary. malloc() is a function used in C programming to allocate a specific amount of memory needed for an array or a variable that will be used at run time. In this lab, we will be learning how to allocate memory dynamically using malloc() and then clear out the memory space using free().

Find Largest Number

Find Largest Number

Difficulty: Beginner | Time: 30 minutes

In this lab, we will write a C program to find the largest number among three user input numbers. We will prompt the user to enter three numbers, and then our program will determine the largest number and print it to the console.

Find Largest and Smallest Numbers Using Global Variables

Find Largest and Smallest Numbers Using Global Variables

Difficulty: Beginner | Time: 20 minutes

In this lab, we will learn how to find the largest and smallest numbers among two input numbers using global declaration in C programming. Unlike local variables, global variables can be accessed and modified by any function within the program. We will use global variables to store the input numbers and solve the problem.

Determine Integer or Float in C

Determine Integer or Float in C

Difficulty: Beginner | Time: 25 minutes

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.
