Code:
#include<conio.h>
#include<stdio.h>
void main()
{
   int a[3][3],i,j,k;
   clrscr();
   printf("\n Enter a Matrix 3x3:\n\n");
   for(i=0;i<=2;i++)
   {
   for(j=0;j<=2;j++)
   {
   scanf("%d",&a[i][j]);
   }
   }
   /* Displaying entered matrix 3x3*/
   printf("\n The Matrix is:-\n");
   for(i=0;i<=2;i++)
   {
   for(j=0;j<=2;j++)
   {
      printf("%d\t",a[i][j]);
   }
      printf("\n");
   }
   printf("\n");
   printf("\n Lower diagonal:\n\n");
   for(i=1;i<=2;i++)
   {
   for(j=0;j<i;j++)
   {
   printf("%d\t",a[i][j]);
   }
   printf("\n");
   }
   printf("\n \n");
   printf("\n Upper diagonal\n");
