A matrix is a 2D array of numbers arranged in rows and columns. Finding the sum of its elements — row by row, column by column, or all at once — is one of the most common matrix operations and a good exercise in nested loops and function design. This post shows two approaches: a …
C Program to find the Multiplication of two matrices. C Program Develop functions a) To read a given matrix b) To output a matrix c) To compute the product of two matrices Use the above functions to read in two matrices A (MxN) B (NxM), to compute the product of the two matrices, to output …
Selection Sort works by repeatedly finding the minimum element from the unsorted portion of the array and placing it at the beginning. After each pass, the sorted portion grows by one element from the left. It always performs exactly O(n²) comparisons regardless of input order — unlike Bubble or Insertion Sort, there is no early …
Write a C program to read N names, store them in the form of an array and sort them in alphabetical order.Output the given names and the sorted names in two columns side by side with suitable heading.Program will sort the name strings using Bubble Sort technique.

This program reads a sentence and swaps the case of every letter — uppercase becomes lowercase, lowercase becomes uppercase. Digits, spaces, and punctuation are left unchanged. The <ctype.h> functions isupper(), islower(), toupper(), and tolower() make this clean and portable across all ASCII and extended character sets. The original post used conio.h, void main(), a broken …
This program reads two matrices of the same order, computes either their sum or difference (user’s choice), and then finds the trace of the result. The trace of a matrix is the sum of its main diagonal elements (positions where row index equals column index). It is defined for any matrix, not just square ones …
