Void doesn't return a value for a function. Then where does the need of such functions come that doesn't return a value?

For example if you want to print something on the screen you don't need that method to return something.
Or if you want to add an element to a list with the method, you don't need anything to be returned either.

Yeap
You will have to either change void to int or whatever, or to remove "return"

Ok and if we try to return a value in such case, will that give error?

not 100% certain but I think that printing an integer to the screen in a void function might lead to an error. However, in my code, I was able to print an integer. My example might e different than what you are referring to.
#include <iostream>
using namespace std;
void hope (int y)
{
cout<< y;
}
int main ()
{
hope(89);
return 0;
}
Jaya, I appreciate your question. It's also confused me.

Yes, it will give an error. "void" simply means "that doesn't return any value". If you return any value in void function then it will definitely give an error
