Array declaration problem

Nov 3rd, 2004

How can i declare an array with variable size? i dont want it to be dynamic array, it have to be static. I mean the following:

Help with Code Tags

(Toggle Plain Text)

int size;
cin>>size;
float array[size];

the previous code when compiled gives me that a constant expression required for the array declaration, although an integer value is already assigned to "size" by "cin" ...
So is there a solution so i can modify the previous code so it'll work?? (without using a dynamic array)..
Appreciated..

The size of the array has to be known when compiling. That's why it must be a constant. The only way around this (that I know of) is allocating the array dynamically.

Why does it HAVE to be static? Is this an assignment where you need to puzzle out some way of doing this? gallas is right, memory allocation is for just such situations.
