Thread: Convert from string to int.

There is no such keyword (other than new, new[], and the making of the variable into a global or member variable, but I suspect those are not what you are looking for here).

One option is to return a value from the function, and then call that function from the other function. You might want to read a tutorial on functions, say the one at cprogramming.com

what i want to do is create an integer array.

but i don't know what size it will be until i have ran other functions within the class.

All I want to do is create the integer array inside say function1 and have it available to other functions when function1 has finished...

Basically my app reads a text file and discovers how many cd objects are in the text file, and then creates an int array of that size. Ie 4 cd's = int container[3]

Then a different function re-reads the file to determine how many tracks there are for each cd and then puts them in.
For example, if container[2] contained the value 6 - that would mean there were 6 tracks on cd 3.

But for this to work , I need Container[] to be available to both functions. Can't create it at the beginning because I'll only know how big it should be after function 1 is ran...



Alternatively maybe sort of declare the int array as a global at the top but not set the size of it until midway?
possible? not?
