Using cin to Input Strings

To input strings with cin, use the get() method:

char text[20];      // declare array of 20 chars
cin.get(text, 20);  // get 19 chars + NULL

If you really want to read 20 characters, you'll need to do this:

char text[21];      // declare array of 20 chars
cin.get(text, 21);  // get 20 chars + NULL

The first parameter is the string that cin will fill with characters
The second parameter is the number of characters to read into the array, including the NULL character
Be sure that your string is large enough to hold the number of characters you want to read
Don't forget about the NULL; cin will automatically append it for you, but you must provide enough space
This is true for any string function: you must ensure that there is enough room in the array; none of the functions does any checking for you
