C语言--递归逆置字符串

编写一个递归函数，来将字符串中的字符反向排列

#include
void reverse_string(char* str, int size, int left, int right) {
 if (left < right) {
  char tmp = str[left];
  str[left] = str[right];
  str[right] = tmp;
  left++;
  right--;
  reverse_string(str, size, left, right);
 }
}
int main() {
 char str[] = {'a','b','c','d','e'};
 int size = sizeof(str)/sizeof(str[0]);
 int left = 0;
 int right = size - 1;
 reverse_string(str, size, left, right);
 for (int i = 0; i < size; ++i) {
  printf("%c ", str[i]);
 }
 return 0;
}
