问题： 该程序应具有允许用户执行以下功能的菜单：
程序只应在用户选择退出程序时终止。
请帮我解决这个问题。
当我运行此C编程代码时，将出现此错误：
Error 16 error C2143: syntax error : missing ';' before 'type' g:\mini project testing\cgpacalculation\cgpacalculation\cgpacalculation4.c 190
Error 17 error C2143: syntax error : missing ';' before 'type' g:\mini project testing\cgpacalculation\cgpacalculation\cgpacalculation4.c 224
请帮我纠正我的编码：

答案 0 :(得分：2)
看起来你将函数menu_two放在另一个函数中。您的Visual C ++编译器不接受本地函数。
与getCalculation相同的问题。根据你的声明，这些声明应该在全球范围内。
答案 1 :(得分：0)
您的代码几乎没有问题 -
menu_two();
} // here you need to close it
void menu_two(void) // remove the semicolon here
因为本地功能不可接受。不要在另一个函数中包含任何函数。
void getCalculation(void) // remove semicolon here
将上述两个功能作为全局功能。任何尝试将必要的信息传递给该功能并尝试。
