Choose the correct option to fill ? 1 and ? 2 so that the program below prints an input string in reverse order. Assume that the input string is terminated by a newline character.
void recerse (void) {
int c;
if (?1) reverse() ;
?2
}
main {
printf ("Enter Text" );
printf("\n");
reverse() ;
printf("\n") ;
}
A
?1 is (getchar ( )! = '\ n')
?2 is getchar (c);
B
?1 is ((c = getchar ( ) )! = '\ n')
?2 is getchar (c);
C
?1 is (c ! = '\ n')
?2 is putchar (c);
D
?1 is ((c = getchar ( ) )! = '\ n')
?2 is putchar (c);
