How can I declare a global array whose size I calculate in a function later on (based on # of rows & columns of terminal ).
Error I am getting: variably modified 'box' at file scopeCode:// global vars
int row, col;
char box[row][col]; // causes error
...
void getsize(){
isatty(STDIN_FILENO);
struct winsize sz;
ioctl(STDIN_FILENO,TIOCGWINSZ,&sz);
row=sz.ws_row;
col=sz.ws_col;
}
