Is there a way to have an array contain a mixture of integers, floates, strings, characters? Just like a Python list.

Null pointer?

look up polymorphism, or polomorphic array i cant remember how to do it but thats what its called/

make a generic object that contains several data types. overload the constructor and accessors. then use malloc() with new to create an array of pointers to your objects.

this will waste a lot of space, though. as every object will have one of everything.

Found vectors and lists, but nothing for mixed types. I guess I could change everything to a string, or a vector of unions.

Yup, there is... it's called a character array...

atof() converts char * to float.
atoi() converts char * to int.

and as for strings, that's what a char pointer is basically...
