c - 错误: expected ';' before '{' token

Question

我最近正在编写一个简短的小型辐射避难所生存游戏，我遇到了错误“预期';'”在“{”标记之前”。错误发生在第 28 行第 23 字符附近:

#include <stdio.h>

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

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

Answer 1

• 您不能在 C 中使用 elif。您应该使用 else if。
• 在 printf 中，%s 不用于打印整数。您应该使用 %d 来代替。
• 对于 char input[15];，像 input == 1 这样的比较没有任何意义。您可以使用int char;。
• input 未初始化。您应该阅读一些数据。
• resources 未定义。应该是resources拼写错误。
• 我将 input 的类型更改为 int 并将 scanf 放在分支之前，因此删除 fgets(input, sizeof(输入)，标准输入)；
• 删除 int Money = Money - 6;、int resources[8] = resources[8] + 2; 中多余的 int和 while(int h > 0)
• 未使用参数，因此将 int main(int argc, char *argv[]) 更改为 int main(void)。 (可选以避免警告)

好的，现在编译错误消失了。

#include <stdio.h>

抱歉，我不喜欢，但很生气。
