Membuat Spiral Matrix

#include <iostream.h>
#include <conio.h>
void main()
{
int d[5][5]; //angka 5 bisa di ganti
int start = 1;
int count = start;

for (int i=0; i<5; i++) {

// pengaturan bagian atas
for (int j=i; j<5-i; j++)
d[i][j] = count++;
count--;

// pengaturan bagian kanan
for (int j=i; j<5-i; j++)

count--;

// pengaturan bagian bawah

count--;

// pengaturan bagian kiri
for (int j=5-i-1; j>i; j--)

if (count > 5*5+start)

gan ane nemu caranya input dari user:
----------------------------------------
#include
#include
void main()
{
int n;
int d[100][100]; //angka 100 bisa di ganti
int start = 1;
int count = start;
cout<<"masukan data : ";cin>>n;
for (int i=0; i=i; j--)
d[n-i-1][j] = count++;
count--;

// pengaturan bagian kiri
for (int j=n-i-1; j>i; j--)
d[j][i] = count++;

if (count > n*n+start)
break;
}

for (int i=0; i<n; i++) {
for (int j=0; j<n; j++) {
cout << d[i][j] << " ";
}
cout << endl;
}

getch();
}
