(C++) Expression must have a constant value [duplicate]
This question already has an answer here:
Using const int as array size
5 answers
Visual Studio is for some weird reason showing me this error and keep saying that count is not const int while trying to initialised array. Check image.
Error: expression must have a constant value
This is function call at main:
std::string fileName("shows.tv");
const int COUNT = 10;
Episode** episodes = loadEpisodesFromFile(fileName, COUNT);
and this is function declaration at header file:
Episode** loadEpisodesFromFile(std::string, const int);
I don't get it. Variable count is already declared as const int but it's not working.

Not totally sure on this, but do you maybe have another variable defined as "count" as a global that this might be getting confused with?

The error sayingconstant valuedoesn't refer to the same thing as aconstvariable. It needs to be known at compile time. Use astd::vectorto allocate dynamic arrays.

Episode* episodes[count] is not valid because count is a parameter from the function
loadEpisodesFromFile which is unknown at compiling time...
you need to use an std::vector instead
std::vector<Episode*> episodes(count);
