假设上面截取的代码进入第二个while循环，如果optionsInv的值为4，则肯定会退出循环

#include <stdio.h>

int main() {
  int menu = 2;

  //  while (menu == 1)
  // {
  //     printf("you made it.");
  // }

  while (menu == 2) {
    // int freeSlots = calcFreeSlots(inventar, sizeInv);
    // int optionsInv = optionsInvQuestion(); //returns an OptionValue for the InvMenuOptions
    int optionsInv = 4;

    switch (optionsInv) {
    case 1: //openInv
      printf("inside case 1\n");
      // printInv(inventar, sizeInv, freeSlots);
      break;

    case 2: //removeItem
      printf("inside case 2");
      printf("Not Implemented\n");
      break;

    case 3: //addItem
      printf("inside case 3");
      printf("Not Implemented\n");
      break;

    case 4: //exitInvMenu
      printf("inside case 4\n");
      menu = 1;
      break;
    }
  }

  printf("outside loop");
  return 0;
}
