Programming in C - I/O Operations
11. The following program fragment int k = -7; printf(“%d", 0 < lk);
- Option : A
- Explanation : k = -7. So, if 'k' is used as a Boolean variable, it will be treated as a true condition. So. ! k will be false i.e., 0. So, 0 < ? !k is actually 0 < 0. which is false. So. 0 will be printed.

14. The following program fragment int a = 4, b = 6; printf ("%d", a = b) ;
- Option : D
- Explanation : Here in this program, the output will be '6' . The program assigns b's value to a. So, a becomes 6. While, the "%d" will display value of the second variable in the printf statement which is "b=6"

- Option : C
- Explanation : Since x > 7 is false, the ternary operator?: returns "%c". So, print f ( "%c ", i) will be executed. So, the ASCII character corresponding to 107, i.e., ' k ' will be printed.
