Thread: square matrix

well,i'm working on this program that has been asked many times.
"The magic squares". here what i got so far. I can compile it with no errors, but with no output. I think i'm not passing the arrays correctly.
Any suggestions?

Code:

#include<stdio.h>

#define MAX 15

void intarray(int [][MAX],int);
void calcsquare(int[][MAX],int);
void printarray(int [][MAX],int);

int main(void)
{
	int num;
	int set_num[MAX][MAX];
	printf("Enter the size of the magic square <15 or less>: ");
	scanf("%d",&num);

	intarray(set_num,num);
	calcsquare(set_num,num);
	printarray(set_num,num);
}
void intarray(int matrix[][MAX],int num)
{
	int row,column;
	//initialize the arrays//
	for(row=0;row<num;row++)
		for(column=0;column<num;column++)
			matrix[row][column] = 0;
}	
void calcsquare(int square[] [MAX],int size)
{
	int next;
	int row =0;
	int column =size/2;
	square[row][column]=1;//place a 1 on center of 1st row//
	
	for(next=2;next<(size*size);next)
	{
		row--;
		column++;
		if(row<0 && column>size-1)
		{
			row=0;
			column=size-1;
		}
		else if(row<0)
		{
			row=size-1;
		}
		else if(column>size-1)
		{
			column=0;
		}
		else if(square[row][column]!=0)
		{
			row =row+2;
			column=column-1;
		}
		
		square[row][column]=next;//continue with the next number//
	}

}
	
void printarray(int matrix[][MAX],int n)
{
	int row,column;
	
	for(row=0;row<n;row++)
		for(column=0;column<n;column++)
	
			printf(" %5d", matrix[row][column]);
			printf("\n");
 

 
}
