Recursion is a programming technique in which a function calls itself to solve a problem. A recursive function repeatedly calls itself until a base condition is met. Without a base condition, the recursion continues indefinitely and may cause a stack overflow. Syntax Components of Recursion Example 1: Factorial Using Recursion The factorial of a number … Read more
A function in C is a block of code that performs a specific task. Functions help make programs easier to understand, reuse, and maintain. Instead of writing the same code multiple times, you can write it once in a function and call it whenever needed. Advantages of Functions Types of Functions in C Components of … Read more
A string in C is a sequence of characters terminated by a null character (‘\0’). Strings are stored in character arrays. For example, the string “Hello” is stored as: 1. Declaration of a String Syntax Example This declares a string that can store up to 19 characters plus the null character (‘\0’). 2. Initialization of … Read more
Arrays in C An array is a collection of similar data elements stored in contiguous memory locations under a single name. Instead of storing multiple variables, arrays allow you to store multiple values in one variable. 1. Declaration of Array Syntax Example This creates an array that can store 5 integer values. 2. Initialization of … Read more
Loops in C (for, while, and do-while) Loops are used to execute a block of code repeatedly until a specified condition becomes false. C provides three types of loops: 1. for Loop The for loop is used when the number of iterations is known in advance. Syntax Example Output 2. while Loop The while loop … Read more
Control Statements in C (if and switch) Control statements determine the flow of execution in a C program. They allow the program to make decisions based on conditions. The two most commonly used decision-making statements are: 1. if Statement The if statement executes a block of code only if the specified condition is true. Syntax … Read more
