C++ : Creating an array with a size entered by the user

Question

I was wondering if we can make an array with a size specified by the user.

Ex:

int a;
cout<<\"Enter desired size of the array\";
cin>>a;
         


        

Answer 1

Use std::vector (requires header ):

int size;
cout<<"Enter desired size of the array";
cin >> size;
std::vector array(size);
