2. Each statement below is either TRUE or FALSE. Choose the most appropriate one andENTER in the “tear-off” sheet attached to the question paper, following instructionstherein. (1x10)

2.1 Sizes of short integer and long integer would vary from one platform to another.

2.2 A structure can contain similar or dissimilar elements.

2.3 Names of functions in two different files linked together must be unique.

2.4 Functions that do not contain return statement do not return any value.

2.5 malloc() allocates memory from the heap and not from the stack.

2.6 Every ‘if’ statement must also include ‘else’.

2.7 The three declarations char **apple, char *apple[], and char apple[][] are same.

2.8 malloc() returns a float pointer if memory is allocated for storing float's and a double pointer ifmemory is allocated for storing double's.

2.9 If we have to execute the program with different set of inputs, we need to recompile the programeach time.

2.10 Compiler translates the of source code into object code before the program can be executed.
