I'm just starting with arrays in C++ and I'm having a problem getting the first character of an array.

This is my code,

1- I enter a name, such as "Jim"

char name[30];
cin.ignore();
cin.getline(name, 30);

2- Right away I try to cout the array

    cout<<"NAME:"<<name; // THIS PRINTS 'im'

I was sure it would print 'J'. What am I doing wrong?

Here is signature of cin.ignore:

istream& ignore (streamsize n = 1, int delim = EOF);

So if you call ignore function without any parameters, it will ignore '1' char by default from input. In this case it ignored 'J'. Remove ignore call and you will get 'Jim'.
