To understand this consider following statements,

While entering the value for str if we enter more than 5 characters then there is no provision in cin to check the array BOUNDS. If the array overflows, it may be dangerous. This can be avoided by using GET( ) function. For example, consider following statement,cin.get ( str, 5 ) ; On executing this statement if we enter more than 5 characters, then get( ) takes only first FIVE characters and ignores rest of the characters. Some more variations of get( ) are available, such as shown below:

get ( ch ) - Extracts one character only get ( str, n ) - Extracts up to n characters into str get ( str, DELIM ) - Extracts characters into array str until SPECIFIED delimiter (such as '\n'). Leaves delimiting character in stream.

get ( str, n, DELIM ) - Extracts characters into array str until n characters or DELIM character, leaving delimiting character in stream.
