Find upper and lower diagonal of 3x3 matrices
 
The code to find upper and lower diagonal of 3x3 matrices

Code: C

#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");
    for(i=0;i<2;i++)
    {
        for(j=i+1;j<=2;j++)
        {
            if(i==1)
            {
                printf("        ");
                printf("%d",a[i][j]);
            }
            else
                printf("%d\t",a[i][j]);
           
        }
        printf("\n");
    }
    getch();
}
