Lets say we have a string named "pie" with the value of "do_something". We also have a function with the name of "do_something" Is there a way to call the function with the name of the value of pie? In this case, do_something?
There is a way to do this in PHP, but since C++ is a compiled language rather than an interpreted one, I have my doubts.
Not directly, but there are a couple work-arounds.
1) use a series of if statements to test the string value then call the function
if( pie == "do_something" )
do_something();
else if(pie == "something_else" )
something_else();
// etc etc for all string values2) use <map> to map string values to function pointers.
3) create a structure that is something like 1) above. Useful if there are lots of functions.
