What is a void pointer?
A void pointer is a C convention for “a raw address.” The compiler has no idea what type of object a void Pointer “really points to.” If you write int *ip; ip points to an int. If you write void *p; p doesn’t point to a void! In C and C++, any time you need a void pointer, you can use another pointer type. For example, if you have a char*, you can pass it to a function that expects a void*. You don’t...

C is a language that can be used to develop both 'user applications' and 'operating systems'. It allows you to have access to the machine language itself if you so choose (inline asm). Most of the unix operating system is written in C.
Does c supports function overloading?
angel421
- Sep 9th, 2011
No. C does not support function overloading, C++ does.
Overloading simply involves having a method with the same name within the class.
Example for Over loading
Class A
{
class a()
{
}
class a(int a)
{
}

If we put volatile keyword before any data type then it tells to the compiler to store the value of the variable to the registers first then perform operations.

Syntax error
but if it is: printf("%d",printf("tim"));
then output is: tim3monuavi26

The Answer is 2. printf function returns the number of characters printed, so it returns 3 and "tim" is already printed due to the call to printf("tim"). So the output is tim 3.
