錯誤：預期';'之前'{'token

Question

我最近編寫了一個簡短的小型後果避難所生存遊戲，我遇到了「預期」錯誤;在'{'token'之前。誤差在28行，23字：

#include <stdio.h> 

int main(int argc, char *argv[])

    int money = 300; 
    int resources[10];

    resources[1] = 200; 
    printf("Welcome!\nFirst we will choose the extra supplies for your shelter!"); 
    while(X < 1) 
    { 
     //Setup the input 
     char input[15];

Answer 1

• 不能使用elif在C.你應該使用else if代替。
• 在printf,%s不適用於打印整數。您應該使用%d。
• With char input[15];，input == 1等比較沒有意義。您可以使用int char;。
• input未初始化。你應該閱讀一些數據。
• recources未定義。它應該是resources的錯字。
• 我改變的input類型int，把scanf分支之前，所以刪除fgets(input, sizeof(input), stdin);
• 在int money = money - 6;，int resources[8] = resources[8] + 2;和while(int h > 0)
• 的參數不用於去除多餘的int S，所以更改int main(int argc, char *argv[])到int main(void)。 （可選，以避免警告）

好的，現在編譯錯誤消失了。

對不起，我不喜歡，但惱火。

Answer 2

在c elif不存在。所以，它給出了這個錯誤。 將elif更改爲else並進行驗證。
