this function run a series of numbers.
if n=3
out put is:
1,1,1
1,1,2
1,1,3
1,2,1
1,2,2
1,2,3
1,3,1
1,3,2
1,3,3
Please help me understand how the increasing process in this function works. I cann't see how the array's elemt increase their values.
Code:void print_num(int n) { int times; times=pow(n,2); while (times--) { for(i=0;i<n-1;i++) { printf ("%d,", arr[i]); } printf ("%d\n",arr[i]); if (++arr[n-1]>n) { arr[n-1]=1; for(j=i-1;j>=0;j++) if (++arr[j]>n) arr[j]=1; else break; } } }
