Declare array in C++ header and define it in cpp file?

Question

This is probably a really simple thing but I\'m new to C++ so need help.

I just want to declare an array in my C++ header file like:

int lettersArr[2         


        

Answer 1

You can do it this way:

in header

extern int lettersArr[26];

in .cpp

int lettersArr[26] = { letA, letB, letC, letD, letE, letF, letG, letH,
        letI, letJ, letK, letL, letM, letN, letO, letP, letQ, letR, letS,
        letT, letU, letV, letW, letX, letY, letZ };
