array size const - not working - klaus1n3 - 25.04.2016

Code:

PHP код:



new const constLen = sizeof(FILE_PATH_PLAYERDATA) + MAX_PLAYER_NAME + 4;

new filePath[constLen];   // ERROR

Compiler:

PHP код:



error 008: must be a constant expression; assumed zero

Where is the problem?

Btw:

PHP код:



new const constLen = sizeof(FILE_PATH_PLAYERDATA) + MAX_PLAYER_NAME + 4;

printf("%i", constLen);

-> NO ERROR

It actually works! Thanks. But I don't know why.

4 is most likely the size of a file extension. If you didn't notice, the variable itself is called filePath.
