When we mention the prototype of a function?
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.

The answer could be "Prototyping".
Then what is the basic difference between function declaration & function prototyping then ?
Thanks.

Function Declaration and function prototyping is nothing but one and the same thing.
It was easy for programmers to call the function with incorrect.
Parameters which needless to say had disastrous runtime consequences.
Thus ANSI C mandates function prototypes as the method for function declaration.

#include<stdio.h>
int main()
{
printf("Welcome to IndiaBIX.com..!");
return 0;
}
What is the error in this program?

Prototype is just declaring the function not declare the body.

Prototype means blue print of a function. It means in our function what type of arguments we require.

Prototype is nothing but an outlook, by seeing it we can able to understand what is the matter that it is going to represent in the program. It just says the information about a particular declared variable or a function. I think your dbt was clarified.

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;
}

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.
