A simple program to find out the diagonal matrix. A diagonal matrix is that type of matrix which has non-zero elements in the diagonal only.

#include<iostream.h>
#include<conio.h>

void main()
{
clrscr();

int m[3][3];


for(int i=0;i<=2;i++)
{
for(int j=0;j<=2;j++)              
{
cout << "enter matrix elements";
cin >> m[i][j];
}
}

for(i=0;i<=2;i++)
{
for(int j=0;j<=2;j++)
{

if(i==j)
{
cout << m[i][j] << "  ";
}
else
{
cout << 0 << "   ";
}
 }
cout << endl;
}
getch();
}
