c_cpp 使用void函数在C中进行递归

Posted 2021-05-14

#include <stdio.h>

// using void functions for recursion

void factorial(int* result, int input)
{
  if(!input) return;
  *result *= input;
  factorial(result, input-1);
}


int main(void) {
  int holder = 1;
  factorial(&holder, 10);
  printf("result is %d\n", holder);
  return 0;
}
