gets( ) receives a string from the keyboard. Why is it needed? Because scanf( ) function has some limitations while receiving string of characters, as the following example illustrates
main( )
{
char name[50] ;
printf ( "\nEnter name " ) ;
scanf ( "%s", name ) ;
printf ( "%s", name ) ;
}
And here is the output…
Enter name Jonty Rhodes
Jonty
The puts( ) function works exactly opposite to gets( ) function. It outputs a string to the screen.
Here is a program which illustrates the usage of these functions:
main( )
{
char footballer[40] ;
puts ( "Enter name" ) ;
gets ( footballer ) ; /* sends base address of array */
puts ( "Happy footballing!" ) ;
puts ( footballer ) ;
}
Following is the sample output:
Enter name
Jonty Rhodes
Happy footballing!
Jonty Rhodes
