从高位开始逐位分割并输出它的各位数字

#include <stdio.h>
int main(void)
{
    int digit, number, pow, t_number;

    scanf("%d", &number);
    t_number = number;
    pow = 1;
    while (t_number > 9)
    {
        pow = pow * 10;
        t_number = t_number / 10;
    }
    while (pow >= 1)
    {
        digit = number / pow;
        number = number - digit * pow;
        pow = pow / 10;
        printf("%d ", digit);
    }
    printf("\n");

    getchar();
    getchar();
    return 0;
}
