void init(void){int rows=GetRows();int columns=GetColumns();double *DEMDATA = new double[rows*columns];}void Render(void){for (int i=0; i<(row*columns); i++) { renderstrip(DEMDATA); }}Quote:Whether the size of an array is determined at run or compile time is unrelated to its scope. In your example it looks like your functions are global, so DEMDATA should be global as well. If the entire program is in one file you could put DEMDATA at file scope, else you could use the extern keyword to make it available to any file that needs it.

...so my question is if there is a way to achieve this with dynamic arrays, since their size is determined at runtime
