Answer
2. Each statement below is either TRUE or FALSE. Choose the most appropriate one and enter your choice in the “OMR” answer sheet supplied with the question paper, following instructions therein. (1x10)
2.1 Functions cannot return more than one value at a time.
2.2 Functions can be called either by value or reference.
2.3 Does the data type of all elements in the union will be same?
2.4 We can allocate a 2-Dimensional array dynamically.
2.5 The function free() is used to release dynamically allocated memory back to the heap for possible reuse.
2.6 If p is a pointer then the expression p = p + 1; adds 1 to the value of p regardless of p's type.
2.7 The string "Bilbo Baggins", may be stored in an array of 13 characters.
2.8 typedef is used to give a new name to a known data type.
2.9 The lifetime of a static variable is the duration of your program's execution.
2.10 Are the three declarations char **apple, char *apple[], and char appl[][] same?
3. Match words and phrases in column X with the closest related meaning/ word(s)/phrase(s) in column Y. Enter your selection in the “OMR” answer sheet supplied with the question paper, following instructions therein. (1x10)
