'如果' 裏面的 '爲' 導致遊戲崩潰 - C語言

Question

下面是一個代碼：（whyerror1.exe）

#include <stdio.h> 
#include <stdlib.h> 
int i, n, health=100; 
int main(void) 
{ 
    for (i=0; i<1; i++) 
    { 
     printf("health: %d\n",health); 
     printf("There is meat on the ground.\n"); 
     printf("Will you eat it?\n"); 
     printf("1: yes 2: no\n"); 
     scanf("%d", n); 
     if(n==1) { 
         system("cls"); 
         printf("Ate it. \n"); 
         printf("There is no people, so it is safe to eat. \n"); 
         printf("Health is increased.\n"); 
         system("pause>nul"); 
         system("cls"); 
         } 
     else if(n==2) { 
         system("cls"); 
         printf("Didn't ate it. \n"); 
         printf("More hunger, less health. \n"); 
         system("pause>nul"); 
         system("cls"); 
         } 
     else { 
        printf("select between 1 and 2. \n"); 
        system("pause>nul"); 
        system("cls"); 
        i=-1; 
     } 
    } 
} 

結果：whyerror1.exe停止工作。 這是怎麼回事？ 我已經嘗試過選擇其他數字。我嘗試了任何數字！ Plz幫助！

Answer 1

scanf("%d", n); 

應該是：

scanf("%d", &n);
