Every square matrix has two diagonals: the main diagonal (top-left to bottom-right, elements a[i][i]) and the anti-diagonal (top-right to bottom-left, elements a[i][n-1-i]). This program reads a square matrix, swaps each main-diagonal element with the anti-diagonal element in the same row, and prints the result. The original post used void main(), a broken scanf format string …
C program to find the frequency of odd numbers and even numbers in the input of a matrix. Program will check the element type, if Matrix element is even, it ads 1 to even counter otherwise ad 1 to odd counter.

Finding the second largest and second smallest elements in an array can be done in a single pass through the data — O(n) time, O(1) space — without sorting. The key is maintaining four running extremes: largest, second_largest, smallest, second_smallest. The original program sorted the array first (O(n²) with bubble sort), then accessed fixed indices …
Sorting in descending order means arranging elements from largest to smallest. The only difference from ascending bubble sort is the direction of the comparison: ascending uses arr[j] > arr[j+1] (swap when left is larger), while descending uses arr[j] < arr[j+1] (swap when left is smaller). This program fixes the original which used void main, a …
C Program to multiply given number by 4 using bitwise operators. Bitwise operators allows to cahnge or edit the specific bits within an integer. Program will multiply a given number by 4 using left shift(<<) bitwise operator.
