UNIT 2 Repetition in Programs, Counting Loops, and the while Statement Repetition, or iteration, is a fundamental concept in programming where a set of instructions is executed repeatedly based on a condition. This is essential for tasks that require repeated actions, such as counting, summing a series of numbers, or iterating over arrays. Counting Loops A counting loop is a type of loop that runs a specific number of times. It often uses a counter variable to keep track of iterations. The for Loop in C The for loop is a control flow statement for specifying iteration, which allows code to be executed repeatedly. The syntax of the for loop includes initialization, condition, and increment/decrement expressions, all in one line. Syntax for (initialization; condition; increment) { // Code to be executed } Initialization: Initializes the loop control variable. Condition: The loop continues as long as this condition is true. Increment: Updates the loop control variable after each iteration. Example: Printing Numbers from 1 to 10 Below is a simple C program that uses a for loop to print numbers from 1 to 10: #include void main() { // Using a for loop to print numbers from 1 to 10 for (int i = 1; i
