@Gunjan: You are right. I also get the same error in dev.

But it will run on code::blocks.

Pointer to a const char can be stored in a regular pointer to a char?

Please explain.

Inthe above program answer is b.

Because we are trying to assign const char* to char.

Here we declare the function only, no calling thats why sub function doesn't execute.

I ran the program in Dev C++ and it point outs the error given in B option.

char *ptr is not a pointer to the function, then how can it point to fun()?

Indi said: 1 decade ago

In gcc if you print the pointer there is no error with that code.

I think the fun() never gets called.
