你能根据整数是一个函数来调用函数吗？

这就是我的意思:

#include <iostream>

using namespace std;

int whichFunction;

int main()
{
    cout << "Which function do you want to call?";
    cin >> whichFunction;

    function[whichFunction](); 
    //If you entered 1, it would call function1 - same with 2, 3
    //or Hihihi (of course only when whichFunction would be a string)
}


void function1()
{
    cout << "Function No. 1 was called!";
}

void function2()
{
    cout << "Function No. 2 was called!";
}

void functionHihihi()
{
    cout << "Function Hihihi was …

我希望对象有一个调用函数的方法(但每个对象应该有一个不同的函数来调用).我将通过展示一个例子来向您展示我的意思:

class Human
{
    public:
        void setMyFunction(void func);  // specify which function to call
        void callMyFunction();  // Call the specified function
};

void Human::setMyFunction(void func)    // ''
{
    myFunction = func;
}

void Human::callMyFunction()    // ''
{
    myFunction();
}

void someRandomFunction()   // A random function
{
    // Some random code
}

int main()
{
    Human Lisa;     // Create Object
    Lisa.setMyFunction();   // Set the function for that object
    Lisa.callMyFunction();  // Call the function specified earlier
}

这个代码(显然)不起作用,但我希望你理解我想要完成的事情.
