cin.getline() is removing the first letting of my input in C++ - c++

Question

When I use this following code, the first string input is displayed correctly, but every string input afterwards is missing the first letter.
#include <iostream>
#include <iomanip>
#include <string>
using namespace std;
int main()
{
//declare arrays
string cd_Name[20] = {""};
string cd_Artist[20]= {""};
//declare variables
int numCD = 0;
cout << "Enter number of CD's: ";
cin >> numCD;
if (numCD <= 20)
{
for (int x = 0; x < numCD; x++)
{
cout << "Enter name of CD " << x + 1 << ": ";
cin >> cd_Name[x];
cin.ignore();
getline(cin, cd_Name[x]);
cout << "Enter the artist of " << cd_Name[x] << ": ";
cin.get();
getline(cin, cd_Artist[x]);
cout << endl;
}//end of for loop
cout << "CD Names Artists" << endl;
cout << "======== =========" << endl;
for (int x = 0; x < numCD; x++)
{
cout << cd_Name[x] <<" "<< cd_Artist[x] << endl;
}//end of for loop
}
else
cout << "You can only enter a Max of 20 CD's" << endl;
//end of if
system ("pause");
return 0;
}//end of main function
An example of the output is shown below:
Enter the number of CD's: 3
Enter name of CD 1: The Battle of Los Angeles
Enter the artist of The Battle of Los Angeles: Rage Against the Machine
Enter name of CD 2: So Far So Good
Enter the artist of o Far So Good: Brian Adams
Enter name of CD 3: Amarte es un Placer
Enter the artist of marte es un Placer: Luis Miguel
CD Names Artists
========= ==========
The Battle of Los Angeles ise Against the Machine
o Far So Good rian Adams
marte es un Placer uis Miguel

I believe you will find this is caused by the cin.ignore() call.
the .ignore() of the istream base class functions by
Extract[ing] characters from the input sequence and discard[ing] them
The default value is to discard One (1) character.
In short,
cin >> cd_Name[x];
cin.ignore();
getline(cin, cd_Name[x]);
Will get the name inputted by the user, Ignore the first character, then extract the string to your array.
If you called cin.ignore(2) it would remove the first two characters, and so on.
Please view this article for more information (http://www.cplusplus.com/reference/istream/istream/ignore/)
[EDIT]
You may find your getline and ignore calls are arbitrary
try using this in your loop:
cin will deliver the resulting string directly into the variable given, you should not need getline, nor ignore to achieve this.
char Name_tmp[50];
char Artist_tmp[50];
for (int x = 0; x < numCD; x++)
{
cout << "Enter name of CD " << x + 1 << ": ";
cin.get(Name_tmp, 50); //get 50 character (max length of string) into string variable
cout << "Enter the artist of " << cd_Name[x] << ": ";
cin.get(Artist_tmp, 50); //get 20 character (max length of string) into string variable
cout << endl;
cd_Name[x] = Name_tmp;
cd_Artist[x] = Artist_tmp;
}//end of for loop
In short, I'm extracting a set number of characters (less can be taken, but no more) from the users input into a temporary C-string, then assigning those values into your array.
Note, I made use of the istream::get method.
[Edit 2]
I noticed David Schwartz's post as to the implementation of using
system ("pause");
Unfortunately, I believe David is an avid linux programmer, and is not familiar with Visual Studio - When a program in run from VS (unless done so without debugging) the program output window closes before you can view the results.
This may also occur with some other IDE's.
My recommendation is to use something like this instead
char tmp[20];
cin.get(tmp, 20);
return;
This will pause and wait for the user to provide some input (a return should count as input in the case of MS Visual Studio)
