Question

所以我真的不知道我的代码有什么问题。任何建议都会有帮助。查看我评论的代码部分（朝向中间）。计算机给我一个错误，说预期“;”。支架有问题，或者我搞砸了其他地方，但却找不到它。

//Experiment2
//Creating functions and recalling them.
#include <iostream>
using namespace std;

void a()
{
cout<<"You try running but trip and fall and the crazy man kills you!!!!                     HAAHAHAHHAHA.";
}


void b()
{
cout<<"You stop drop and roll and the crazy man is confused by this and leaves you alone!";
}

void c()
{
cout<<"you try fighting the man but end up losing sorry!";
}




int main()
{
int a;
int b;
int c;
int d;
a=1;
b=2;
c=3;

cout<< "Once upon a time you was walking to school,\n";
cout<< " when all of the sudden some crazy guy comes running at you!!!!"<<endl;
cout<< " (This is the begining of your interactive story)"<<endl;
cout<< "Enter in the number according to what you want to do.\n";
cout<< " 1: run away, 2:stop drop and roll, or 3: fight the man."<<endl;
cin>>d;
void checkd()
//i dont know whats wrong with the bracket! the computer gives me an error saying expected a";"
{
    if(d==1)

    {
        void a();
    }

    if(d==2)

    {
        void b();
    }

    if(d==3)

    {
        void c();
    }
}
}

您无法在其他功能中定义功能。您在checkd()函数中定义了函数main。

将函数体移到main之外，只需将main中的函数调用为：

checkd(d);

或许，您还希望函数采用需要比较的参数。

另外，

void a();

不调用函数a()它只是声明函数，调用你需要的函数：

a();

void checkd(int d)

{
    if(d==1)

    {
        a();
    }

    if(d==2)

    {
        b();
    }

    if(d==3)
    {
        c();
    }
}
int main()
{
    ....
    ....
    cout<< " 1: run away, 2:stop drop and roll, or 3: fight the man."<<endl;
    cin>>d;
    checkd();

    return 0;
}

c ++编译错误/语法错误？错误原因未知
