What is the Code for doubly even magic square?

Answer 1

#include<stdio.h>

#include<string.h>

void main()

{

int kute=0;

int ms[100][100],n,i,j,num;

while(scanf("%d",&n)==1)

{

if(!n%2)

{

printf("Enter a odd number 1-99\n");

continue;

}

memset(ms,0,sizeof(ms));//set all element to 0 as well false

num=1;i=n/2;j=n-1;//1st step

while(1)

{

if(num>n*n)break;

if(i==-1&&j==n){j=n-2;i=0;}//3rd condition

else {

if(j==n)j=0;//1st condition helper if next number is goes to out of box right side

if(i<0)i=n-1;//1st condition helper if next number is goes to out of box upper side

}

if(ms[i][j]){j--;j--;i++;continue;}//2nd condition

else

ms[i][j]=num++;//set number

j++,i--;//1st condition

}

//print magic square

printf("The Magic Square for %d:\nSum of each row or column %d:\n\n",n,(n*n*n+n)/2);

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

{

for(j=0,num=0;j<n;j++)

{

printf("%2d ",ms[i][j]);

num+=ms[i][j];

}

printf(" %d\n\n",num);

}

getch();

}
