first (&second);

first (second);

none of the above

Discuss

Answer: (c).first (second);

Q422.

A function q that accepts a pointer to a character as argument and returns a pointer to an array of integer can be declared as

int (*q (char*) )[ ]

Int *q(char *)[ ]

int (*q) (char *)[ ]

none of the above

Discuss

Answer: (a).int (*q (char*) )[ ]

Q423.

If func is a function needing three arguments a1, a2, a3 then func can be invoked by

func(a1, a2, a3) ;

(*func)(a1, a2, a3);

*func(a1, a2, a3);

both (a) & (b)

Discuss

Answer: (d).both (a) & (b)

Q424.

The declaration
int (*p) [5];
means

p is a one dimensional array of size 5, of pointers to integers

p is a pointer to a 5 element integer array

the same as int *p[5];

none of the above

Discuss

Answer: (b).p is a pointer to a 5 element integer array

Q425.

Consider the declaration

int a = 5, *b = &a;

The statement
printf("%d", a * b);
prints

garbage

5 x address of b

an error message

Discuss

Answer: (d).an error message

Q426.

Consider the following segment. Cchoose the statements having errors

char *a, *b, c[10], d[10];
 a = b;
 b = c;
 c = d;
 d = a;

no error

a = b; and b = c;

c = d; and d = a;

a = b; and d = a;

Discuss

Answer: (c).c = d; and d = a;

Q427.
