Program to Interchange Diagonals of Matrix in C program
In this tutorial, we will be discussing a program to interchange the diagonals of a given matrix.
For this, we will be given with a square matrix of the order n*n. Our task is to interchange the elements in the two diagonals of the matrix and then return the new matrix.
Example
#include<bits/stdc++.h> using namespace std; #define N 3 //interchanging the two diagonals void int_diag(int array[][N]){ for (int i = 0; i < N; ++i) if (i != N / 2) swap(array[i][i], array[i][N - i - 1]); for (int i = 0; i < N; ++i){ for (int j = 0; j < N; ++j) printf(" %d", array[i][j]); printf("
"); } } int main(){ int array[N][N] = {24, 45, 64, 17, 21, 34, 75, 38, 98}; int_diag(array); return 0; }
Output
64 45 24 17 21 34 98 38 75
