getline function does not seem to activate

As a complete beginner, I have just started working through "Jumping into C++". I am at the section on appending strings. The tutorial mentions the getline function but I can not seem to get it to activate. There is no mention of any other inclusions.

Code:

---

#include <iostream>
#include <string>

using namespace std;

int main()
{
    string user_first_name;
    string user_surname;
    string title;
    string address;

    double x = 0;
    double y = 0;
    double z = 0;

    cout << "Before we start, why not tell me your  first name : ";
    cin >> user_first_name;
    cout << "Ok, for the sake of formalities, what is your surname? : ";
    cin >> user_surname;
    cout << "And is that Mr, Mrs or Ms? : ";
    cin >> title;
    string user_full_name = title + " " + user_first_name + " " + user_surname;
    cout << "And what is your street address? : ";
    getline ( cin, address );
    cout << "Hi " << user_first_name << " nice to meet you.\n";

I note that the getline function color remains black while other functions are green. I presume this means that Codeblocks has not associated it with any of the listed header files. Has the tutorial omitted this detail?

No, you're fine. getline is defined in <string>.

The compiler does not report any errors when I build however when run, the program skips from the results of line 24 to line 26. No user input for line 25 occurs.

That is because the newline is left in the input buffer after your previous cin >> title;

One solution is to get rid of that newline with cin.ignore. Another option is to read line by line with getline, then parse the string, e.g., using a stringstream.

You need to use ignore() when you switch from cin >> to getline, since they have different ideas as to what is a delimiter.

Eg.

Code:

---

#include<iostream>
#include<string>
#include<limits>
using namespace std;
int main()
{
  int a;
  string b;
  cin >> a;
  cin.ignore(numeric_limits<std::streamsize>::max(),'\n');
  getline(cin,b);
  cout << "a=" << a << endl;
  cout << "b=" << b << endl;
}
