Pattern programs in C use nested loops to print shapes made of characters — stars, numbers, or letters. They are among the most commonly set exercises in first-semester C programming courses because they teach how to control the exact number of characters printed per row by expressing it as a formula of the row number. …
C Program to demonstrate the Ternary conditional operator(?). Ternary operator is a short hand combination of the if-else statement. You can use the ternary operator in initialize lists.

The binomial coefficient C(n, k) — read as “n choose k” — counts the number of ways to choose k items from a set of n distinct items, regardless of order. It appears in the expansion (x + a)ⁿ as the coefficient of each term, in probability calculations, in Pascal’s triangle, and in combinatorics. There …
Converting a binary number to decimal, octal, and hexadecimal in C demonstrates how the same bit pattern can be expressed in different bases. Binary uses base 2, decimal uses base 10, octal uses base 8, and hexadecimal uses base 16. Once you have the decimal value, C’s printf format specifiers (%o and %X) handle octal …
The subset sum problem asks: given a set of integers and a target sum, find all subsets of the set whose elements add up to the target. It is a classic application of backtracking — a systematic method that builds candidates incrementally and abandons a partial candidate (“prunes”) as soon as it determines the candidate …
Depth First Search (DFS) is a graph traversal algorithm that explores as far as possible along each branch before backtracking. Starting from a source node, it follows one path all the way to a dead end, then backtracks and tries the next unvisited neighbor. DFS uses a stack — either an explicit one or the …
