Programming in C - Constants, Variables and Data Types
31. If integer needs two bytes of storage, then maximum value of a signed integer is
- Option : B
- Explanation : In signed magnitude form, one bit is dedicated to store the sign. (e.g.. 1 for negative and 0. otherwise). Only the remaining 15 bits arc available to store the magnitude. Hence the answer.
32. printf ( "%d" , printf ( "tim" ) ):
- Option : B
- Explanation : Any function (including main ( ) ) , returns a value to the calling environment. In the case of printf, it is the number of characters it printed. So. the output will be tim3 (since it printed the three characters a, b, c).
- Option : D
- Explanation : Take reference from below. Any function (including main ( ) ) , returns a value to the calling environment. In the case of printf, it is the number of characters it printed. So. the output will be tim3 (since it printed the three characters a, b, c). The scanf function returns the number of successful matches. i.e., 3 in this case.
- Option : B
- Explanation : The input is actually a \ n b. Since we are reading only two characters, only a and \ will be read and printed.
