Calling a Function From a String With the Function’s Name in C++

Question

How can I call a C++ function from a string?

Instead of doing this, call the method straight from string:

void callfunction(const char* callthis, int         


        

Answer 1

Alternative: You could use array of function pointers and call the desired function using its index.

typedef void (*TFunc)(int, int);

TFunc arrptr[100];

void callFunction(int index, int params[])
{
    (*arrptr[index])(params[0], params[1]);
}
