C Program: Ramanujan Magic Square

Ramanujan Square:

#include<stdio.h>
int main()
{
 int i[100][100];
 int R,L,date,month,year,j,k;
 printf("\nEnter your date of birth:");
 scanf("%d",&date);
 printf("\nEnter your month of birth:");
 scanf("%d",&month);
 printf("\nEnter your year of birth:");
 scanf("%d",&year);
 i[1][1] = date;
 i[1][2] = month;
 L = year/100; //left part of year
 R = year%100;   //right part of year
 i[1][3] = L;
 i[1][4] = R;
 i[2][1] = i[1][4] + 1;
 i[2][2] = i[1][3] - 1;
 i[2][3] = i[1][2] - 3;
 i[2][4] = i[1][1] + 3;
 i[3][1] = i[1][2] - 2;
 i[3][2] = i[1][1] + 2;
 i[3][3] = i[1][4] + 2;
 i[3][4] = i[1][3] - 2;
 i[4][1] = i[1][3] + 1;
 i[4][2] = i[1][4] - 1;
 i[4][3] = i[1][1] + 1;
 i[4][4] = i[1][2] - 1;
 printf("\n\nYour Magic Square:\n");
 for(j=1;j<=4;j++)
