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();}`
