problem 1: Describe the meaning of each of the given pointer declarations:

i) float a = -0.137;
   float *pa = &a;

ii) double *fa(double *a, double *b, double *c);

iii) char *d[4] = {“north”, “south”, “east”, “west”};

iv) int (*pf)(char *a, char *b);

problem 2: Read the structured program shown below and answer the problems:

int i, j = 25;
int *pi, *pj = &j;
*pj = j + 5;
i = *pj + 5;
pi = pj;
*pi = i + j;

Suppose each integer quantity occupies 2 bytes of memory, the hexadecimal address of i begins at F9E and that of j at FA0.

i) What value is symbolized by &i?
ii) What value is symbolized by &j?
iii) What value is assigned to pj?
iv) What value is assigned to *pj?
v) What value is assigned to i?
vi) What value is symbolized by pi?
vii) What final value is assigned to *pi?
viii) What value is symbolized by (pi + 2)?
ix) What value is symbolized by the expression (*pi + 2)?
x) What value is symbolized by the expression *(pi + 2)?

problem 3: prepare a suitable declaration for each of the given situations comprising the pointers.

a) Declare a function which accepts an argument which is a pointer to an integer quantity and returns a pointer to a six-element character array.

b) Declare a function which accepts an argument which is a pointer to an integer array and returns a character.

c) Declare a function which accepts an argument which is an array of pointers to integer quantities and returns a character.

d) Declare a function which accepts an argument which is an integer array and returns a pointer to the character.

e) What is the main purpose of the buffer area when working with a stream oriented data file?

f) How is the buffer area defined? Describe your answer with suitable sample code.
