Question: Can we use scanf( ) function to scan a multiple words string through keyboard?
Answer: Yes. Although we usually use scanf( ) function to receive a single word string and gets( ) to receive a multi-word string from keyboard we can also use scanf( ) function for scanning a multi-word string from keyboard. Following program shows how to achieve this.main( ) { char buff[15] ; scanf ( "%[^n]s", buff ) ; puts ( buff ) ; } In the scanf( ) function we can specify the delimiter in brackets after the ^ character. We have specified 'n' as the delimiter. Hence scanf( ) terminates only when the user hits Enter key. |
