Call different functions for different values of an integer

[VladtheMage]

I want to call different functions depending on the value of an integer without having a huge if...then tree. I don't really have any code yet because I'm at a loss as to what I need to do. Any help?

Use a switch statement:

Are the possible values a continuous range?
If yes, then an array of function pointers is feasible.

an array of function pointers is feasible

You can have an array of functions?

You can have an array of function pointers which you can then use to call the respective functions.

#include <iostream>
using namespace std;

void func1 ()
{   cout << "func1" << endl;
}
void func2 ()
{   cout <<"func2" << endl;
}
void func3 ()
{   cout << "func3" << endl;
}

typedef void (*func_ptr_t)();

func_ptr_t func_tbl [3] = 
{   func1,
    func2,
    func3,
};

int main ()
{  for (int i=0; i<3; i++)
     (*func_tbl[i])();  // Call the function through the table 
    system ("pause");
}
