A program to print all diagonal elements in a matrix.
In the given matrix output should be like:
3->2->4->7->1->8->3->8->7->9->4->2->6->6->0->6->1->5->3->8->9->4->2->1->2
*/
#include <iostream>
using namespace std;
int main(){
int i,j,m=5,n=5;
int mat[5][5] = { {3,4,8,9,0},
{2,1,7,6,3},
{7,8,6,5,4},
{3,2,1,9,1},
{4,6,8,2,2}
};
for(i=0; i<5; i++){
for(j=0; j<5; j++){
cout << mat[i][j] << " ";
}
cout << endl;
}
int row=0, col=0;
int count = 0;
while(count < (m+ (n-1))){
//cout << count << endl;
for(row=0; row<5; row++){
for(col=0; col<5; col++){
if(row+col == count){
//cout << "Row: " << row << " :: Col: " << col << " :: Count: " << count << endl;
