按照题目要求完成

解题思路:

注意事项:

参考代码:

#include

#include"math.h"

using namespace std;

uint8_t digitNum(uint32_t num) {//数字长度判断

for (uint8_t i = 1;; i++) {

if (pow(10, i) > num)return i;//若是10的i次方大于输入数就返回次方值

if (i == 10)return 1;

}

}

void StringDisp() {

int InNum;

char InChar[20] = {0};

scanf("%d", &InNum);

int NumSize = digitNum(InNum);

for (int i = NumSize-1, chSize = 0; i > -1; i--, chSize+=2) {

InChar[chSize] = (InNum / (int)pow(10, i) % 10) + 48;

InChar[chSize+1] =' ';

}

printf("%s", InChar);

}

int main() {

StringDisp();

return 0;

}
