C++ printing spaces or tabs given a user input integer

You just need a loop that iterates the number of times given by n and prints a space each time. This would do:

while (n--) {
  std::cout << ' ';
}

cout << "Enter amount of spaces you would like (integer)" << endl; 
cin >> n;
//print n spaces
for (int i = 0; i < n; ++i)
{
   cout << " " ;
}
cout <<endl;

Just use std::string:

std::cout << std::string( n, ' ' );

In many cases, however, depending on what comes next, is may be simpler to just add n to the parameter to an std::setw.
