8. WRITE A C PROGRAM TO IMPLEMENT A MAGIC SQUARE OF SIZE N.

DEFN: A MAGIC SQUARE IS AN ARRANGEMENT OF NUMBERS

(USUALLY  INTEGERS)  IN  A  SQUARE  GRID,  WHERE  THE  NUMBERS

IN EACH ROW, AND IN EACH COLUMN, AND THE NUMBERS THAT

RUN DIAGONALLY IN BOTH DIRECTIONS, ALL ADD UP TO THE

SAME  NUMBER.

SOURCE CODE:

#include <stdio.h>

int main() {

int n,row,col,next_row,next_col,n,i,j,start;

int magic[99][99];

int max ;

printf("Enter size of magic square: ");

scanf("%d", &n);

start = (n / 2);

max = n * n;

magic[0][start] = 1;

for (i = 2, row = 0, col = start; i < max + 1; i++) {

if ((row - 1) < 0) {

next_row = n - 1;

}

else { next_row = row - 1; }

if ((col + 1) > (n - 1)) {

next_col = 0;

}

else { next_col = col + 1; }

if (magic[next_row][next_col] > 0) {

if (row > (n - 1)) {

next_row = 0;

}

else {

next_row = row + 1;

next_col = col;

}

}

row = next_row;

col = next_col;

magic[row][col] = i;

}

for (i = 0; i < n; i++) {

for (j = 0; j < n; j++) {

printf("%4d", magic[i][j]);

}

printf("\n");

}

return 0;  

}
