BFS Algorithm in C – Adjacency Matrix and List with Example

Breadth First Search (BFS) is a graph traversal algorithm that explores nodes level by level — starting from a source, it visits all immediate neighbors first, then their neighbors, and so on. Because of this level-by-level behavior, BFS always finds the shortest path in an unweighted graph. It is used in GPS navigation, social network …

C Program to find the Inverse of the Matrix.

C Program to find the Inverse of a Matrix. To find the Matrix Inverse, matrix should be a square matrix and Matrix Determinant is should not Equal to Zero. if A is a Square matrix and |A|!=0, then AA’=I (I Means Identity Matrix).

Dijkstra’s Algorithm in C – Shortest Path with Step-by-Step Trace

Dijkstra’s algorithm finds the shortest path from one source vertex to all other vertices in a weighted graph with non-negative edge weights. It is a greedy algorithm: at each step it picks the unvisited vertex with the smallest known distance, marks it done, and relaxes its neighbours — updating any neighbour’s distance if a shorter …

0-1 Knapsack Problem in C – DP Solution with Table Trace

The 0-1 knapsack problem asks: given a set of items each with a weight and a value, and a knapsack with a maximum weight capacity, which items should you pack to maximize the total value? Each item can be taken once (0-1) — you cannot take a fraction. This is a classic dynamic programming problem …

C Program to count number of characters in the file

C Program to count number of characters in the file. In this program you can learn c file operations. Here we counting the characters by reading the characters in the file one by one and if read character was not an ‘n’ ,’t’ or EOF, it increments the counter by one. Read more about C …

C Program to Demonstrate the increment and decrement operators

C program which demonstrates the working of increment(++) and decrement(–) operators. Increment operator ++ adds 1 to its operand and Decrement operator — subtracts 1 from its operand. These operators may be used either as a prefix operator or post-fix operator.
