Good day .. new to C++ .. wondering if one could offer some insight/suggestions how I might achieve a desired goal.
I'd like to have a loop that within a number of functions are called, but where an event external to the loop causes the actual code executed by the function(s) changes. Hoping to accomplish without numerous select/case if/else etc.
Is it possible to pass a function "pointer" to a function ?
Pass a parameter to the code that is executed?
THANKS in advance for any assist you might offer !
You can absolutely use a pointer to a function to change the function that you will call at runtime. If you could post a simple example of your loop and how you want to modify which function you call we can help you figure out the syntax.
In this example we declare a function called execute_function that will execute a function taking an int as parameter. In our main function, we the call this function with either func1 or func2. This example will produce the result:
