const as array size

[asit]

We know that array size can be a constant integer.

Consider the following case ??

calss myc
{
const int size;
int arr[size];
public:
myc(int x):size(x){}
}

Why the above code shows an error ??

How can we overcome it ??

because array size needs to be a compile time constant integer

by using std::vector<int >
