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);

Consider the following C program:
void foo (int n, int sum) {
int k = 0, j = 0;
if(n==0) return;
k=n%10; j = n /10;
sum = sum + k;
foo(j, sum);
printf("%d",k);
}
int main () {
int a = 2048, sum = 0;
foo(a, sum);
printf("%d\n", sum);
}

A
8, 4, 0, 2, 14
B
8, 4, 0, 2, 0
C
2, 0, 4, 8, 14
D

Consider the following C program:
double foo(double); /* Line 1 */
int main () {
double da, db;
//input da
db = foo(da);
}
double foo(double a){
return a;
}
The above code compiled without any error or warning. If Line 1 is deleted, the above code will show:
A
no compile warning or error
B
some compiler-warnings not leading to unintended results
C
some compiler-warnings due to type-mismatch eventually leading to unintended results
D
compiler errors
