Identify the digits in a given number.

Question

I\'m new to programming, and I\'m stuck at a problem. I want my program to identify the separate digits in a given number, like if I input 4692, it should ident

Answer 1

Another approach is to have two loops.

1) First loop: Reverse the number.

int j = 0;
while( i ) {
   j *= 10;
   j += i % 10;
   i /= 10;
}

2) Second loop: Print the numbers from right to left.

while( j ) {
   std::cout << j % 10 << ' ';
   j /= 10;
}

This is assuming you want the digits printed from right to left. I noticed there are several solutions here that do not have this assumption. If not, then just the second loop would suffice.
