c - 如何在C中调用一个函数？另外，为什么几乎每一行代码都是错误的？

Question

我是 C 的新手，我制作这个游戏只是为了练习我已经知道的东西。我不太明白如何使代码从一个函数转到另一个函数(也许称为调用函数？)。我已经编译并测试了几次，但每次至少有一件事不起作用，我盲目地继续(可能不是一个好主意)，现在我不能继续了。还没完。

注意 is 并不是说​​它在函数 war 中。

Answer 1

你的问题在这里:

 if(squad1==2)
        loyalty ++;
    }

您有右大括号，但没有左大括号。这个简单的语法错误导致了从这一点到文件末尾的一波编译错误。

请注意，第 136 行是第一个报告语法错误的地方，紧接在上述代码段之后。
