Which of the following about the following two declaration is true i ) int *F() ii) int (*F)()
Both are identical
The first is a correct declaration and the second is wrong
The first declaraion is a function returning a pointer to an integer and the second is a pointer to function returning int
Both are different ways of declarin pointer to a function

#2 = 2
expr=2
x/y=2
None
Which of the following is true of the following program
main() { char *c; int *p; c =(char *)malloc(100); ip=(int *)c; free(ip); }
The code functions properly releasing all the memory allocated
Results in compilation error as pointer of various types cannot be equated
The program tries to alt
const
