| cin leaves the newline character in the stream. Adding cin.ignore() to the next line clears/ignores the newline from the stream. This is used mainly with combinations of cin and getline. I can't think of any examples but over time you will find them if you use getline and cin together. Take a look at this: http://www.cplusplus.com/forum/articles/6046/ | |

ignore() will flush the input stream, just like C fflush(stdin), which is great for removing the annoying new lines stored at the end of the stream :P | |
