Question

求c语言，输出魔方阵，所谓的魔方阵是指每一行每一列及对角线之和均相等（魔方阵阶数只能是奇数）

Answer 1

#include <stdio.h>
int main()
{ int a[15][15],i,j,k,p,n;
p=1;
while(p==1)
{printf("enter n(n=1--15):");
scanf("%d",&n);
if ((n!=0) && (n<=15) && (n%2!=0))
p=0;
}
for (i=1;i<=n;i++)
for (j=1;j<=n;j++)
a[i][j]=0;
j=n/2+1;
a[1][j]=1;
for (k=2;k<=n*n;k++)
{i=i-1;
j=j+1;
if ((i<1) && (j>n))
{i=i+2;
j=j-1;
}
else
{if (i<1) i=n;
if (j>n) j=1;
}
if (a[i][j]==0)
a[i][j]=k;
else
{i=i+2;
j=j-1;
a[i][j]=k;
}
}
for (i=1;i<=n;i++)
{for (j=1;j<=n;j++)
printf("%5d",a[i][j]);
printf("\n");
}
return 0;
}
