You will have to use malloc(), calloc() and realloc() to allocate space on
the free store. 


C99 provides the notion of variable length arrays which are built in arrays
whose size can be defined at runtime (but cannot be changed during their
lifetime). Dev-C++ (MINGW) supports C99 with the option -std=c99.


Example of VLA:


int size=7;

int myvla[size];

and

void whatever(int myvla[*]);
