从高位开始逐位输出一个整数的各位数字(不用数组)

程序填空，不要改变与输入输出有关的语句。输入一个正整数repeat (0<repeat<10)，做repeat次下列运算：输入一个整数，从高位开始逐位输出它的各位数字。输出语句：printf("%-2d", digit);例：括号内是说明输入3   (repeat=3) 23456-6008输出2 3 4 5 66 0 08

#include <stdio.h>int main(void){    int digit, in, power, temp;    int repeat, ri;    scanf("%d", &repeat);    for(ri = 1; ri <= repeat; ri++){        scanf("%d", &in);if(in < 0) in = -in;power = in;int k = 1;temp = 0;while(power){temp++;k *= 10;power /= 10;}power = in;while(temp){k /= 10;digit = power/k;power %= k;printf("%-2d", digit);temp--;}     printf("\n");   }}
