For example if an integer array is declared:
And here a vector of integers:
vector<int> ar; //OR vector<int> ar(12);
In either case, is memory allocated to the array at compile time or runtime? I know that vector class in C++ STL uses dynamic memory allocation but what about the ordinary array? Also:
int n; cin >> n; char ar[n];
If memory allocation is at compile time then how does this work? I can’t find anything scavenging the net.
