Issue
I was trying to get the user input and it should include a space because I am asking for a full name. So I used the getline method but I can't input the data correctly. Here's the code:
#include <iostream>
#include <string>
string name, mobile, landline, work;
cout << "Enter the name of the contact to be added:";
getline(cin, name);
cout << "Enter the mobile number of this contact:";
getline(cin, mobile);
cout << "Enter the landline number of this contact:";
getline(cin, landline);
cout << "Enter the work number of this contact:";
getline(cin, work);
When I run the program this is what I get:
Enter the name of the contact to be added:Enter the mobile number of this contact:

I am not able to input each value individually.
Do you know how can I fix this problem?
Thank you for your help.
Solution
How @NathanOliver has suspected you used a cin. In your main method in lines 111 and 153 (if formated in the same way as above) you can find them. Try to change them to getline() too. That should work.
