Programming Unit 2: Repetition and Loops

Study Notes

Repetition in Programs

Repetition (iteration) is fundamental in programming to execute a set of instructions multiple times based on a condition.
Common use cases include counting, summing numbers, and iterating over arrays.

Counting Loops

Counting loops run a set number of times and utilize a counter variable to track iterations.
They are essential for performing repeated actions within a defined range.

The for Loop in C

A for loop allows execution of code repetitively with initialization, condition, and increment all defined in one statement.
Syntax breakdown:
- initialization: Sets the loop control variable's starting value.
- condition: Loop execution continues while this expression evaluates to true.
- increment: Updates the loop control variable after each iteration.

Example of for Loop

C program example to print numbers from 1 to 10 using a for loop:

#include <stdio.h>
void main() {
   for (int i = 1; i <= 10; i++) {
      printf("%d\n", i);
   }
}
