Answer the follwoing

2. What can I safely assume about the initial values of variables which are not explicitly initialized?


3. Why can’t I initialize a local array with a string?
   
4. What is the difference between char a[] = “string”; and char *p = “string”; ?
   
   
5. How do I initialize a pointer to a function?

[VeeranjaneyuluT]

1. It will have some junk value if you are not initialized explicitly.

2. I think we can do this(We can initialize a local array with a string).

3. char a[]= "string"; --> we can not change the base address like a++.

char* p = "string"; -----> it will allow to do modifications like p++ etc.

4.int (*ptrFunction)(float, char, char) = NULL;

Hi,


4.type (*fptr) ();


fptr=pointer to a function
