TYPEDEF OBJECTIVE PROBLEMS

Q1-In the following code, the P2 is Integer Pointer or Integer? typedef int *ptr; ptr p1, p2;

A. Integer B. Integer pointer C. Error in declaration D. None of above ANS - B; EXPLANATION  typedef int* ptr is same as typedef int *ptr in case of typedef declaration . 2.  In the following code what is 'P'? typedef char *charp; const charp P; A. P is a constant B. P is a character constant C. P is character type D. None of above ANS - non  now p is a contant pointer . note --typedef const char *charp;  this is not a valid declaration since typedef doesn't declare an instance of a variable, it declares a type (type alias actually), const is a qualifier you apply to an instance, not a type, so you can use static when you use the type. 3.  What is x in the following program? #include<stdio.h> int main() { typedef char (*(*arrfptr[3])())[10]; arrfptr x; return 0; } A. x is a pointer B. x is an array of three pointer C. x is an array of three function pointers D. Error in x declaration ans- c explanation The return value of the function whose function pointer can be any of arrfptr[n]will be a pointer to an array of 10 characters.  The declaration can interpreted as "type of the array to be returned by function(char) (Returning char pointer(*)(function pointer name(*arrfptr)[size of the array of function pointers](3)(parameters)(void))[size of the array which will be returned from the function]. #include<stdio.h> int main() { enum color{red, green, blue}; typedef enum color mycolor; mycolor m = red; printf("%d", m); return 0; }
