c++ - Array size declarator, can they be calculated? VC++ -

-

ubernoob question: possible in ms visual c++ declare array size based upon user input?

int usernum; cin >> usernum; const int size = usernum; int myarray[size];

it seems if use variable in way initialize constant size, vc++ no longer sees constant purposes of setting array size.

is there way around this?

this can done usign std::vector

#include <iostream> #include <vector>   int main() {   int usernum;   std::cin >> usernum;   std::vector<int> myarray(usernum);   myarray[1]=42;   return 0;    }

note example has no checks size user has entered.
