Thank you for your reply.

My objective is simple. Assume  I have a constant vector, say Vector. in C++
code, I want to do:


int index;
cout<<"Please enter the index of the element you want to look at Vector :";
cin>>index
cout<<Vector[index]


I want every user to be able to do this.

As I understand, scan can only read data from a fixed file. Can I just get
the input from the shell directly?

Thanks
