When we mention the prototype of a function?
Defining
Declaring
Prototyping
Calling
Answer: Option
Explanation:

A function prototype in C or C++ is a declaration of a function that omits the function body but does specify the function's name, argument types and return type.

While a function definition specifies what a function does, a function prototype can be thought of as specifying its interface.

@Vikas.

defining and initializing
int a=20;

defining without initialization :
int a;

initializing already defined variable a
a=20;
(1)

What is the difference between initializing and defining?

Vignesh said:   7 years ago
Prototype means: Gives a function name and args types.

For eg:sum funcall (10, 20), where funcall is an prototype means function name. Where does omit about the interior body of that function.

Please tell me the difference between declaration and definition.

Prototypes are just like declarative statements which tell the compiler that the type of the input and type of the parameter and what the function is doing. They are like interface to complier.

Hi friends:

Can you explain this program?

in()
{ int arr[]={ 1,2,3,4 };
int *ptr ;;;;
ptr++ = arr;
printf("%d,%d",ptr[2],arr[2]);
return 0;
}
