Declaring an array with a non-constant size variable
This is my code:
const int xsize=150;
char Hey[xsize];
I don’t understand why I cannot declare my new array Hey using the constant above.
Can anyone help in this?
It’s not valid C89 code. You can’t declare an array with variable size, even if the variable happens to be
const.It would work if you had it as a
#definerather than aconst int. It is valid in C99, though. GCC and other compilers also offer it as an extension in C89 mode.
