step1/step1.c:3:5: error: redefinition of ‘main’ int main(void) ^~~~ In file

当我在头歌和oj上刷到有关递归的题目时,这是网站自带的编译器报了上面的错误
题目如下:编写一个递归函数,能正序输出一个多位整数的各位数字。
#include<stdio.h> void printDigit(int n) { if (n > 9) { printDigit(n / 10); }
printf("%d ", n % 10); } int main() { int n = 0; scanf("%d", &n);
printDigit(n); }
上面是我写的代码,下面是改正后的代码。
void printDigit(int n) { if (n > 9) { printDigit(n / 10); } printf("%d ", n %
10); }
直接把main函数删掉,就可以解决问题,因为网站自带的在线编译包含了main函数
