Bubble Sort is the simplest sorting algorithm to understand and implement. It works by repeatedly comparing adjacent elements and swapping them if they are in the wrong order. After each pass, the largest unsorted element has “bubbled up” to its correct position at the end — just like air bubbles rising to the surface of …
Binary search in C finds a target value in a sorted array by repeatedly halving the search space. At each step it compares the target against the middle element: if they match, the search is done; if the target is smaller, discard the right half; if larger, discard the left half. This gives O(log n) …
Finding the largest of three numbers is one of the first real decisions a C program has to make. It sounds simple, but it teaches you conditional logic, how the if-else ladder works, and why wrapping repeated logic in a function pays off immediately. This post shows three approaches — a plain if-else, a ternary …
