What do you mean by " a function will perform the desired operations without returning a value" ??

Question

does this mean we won't get a answer.

Answer 1

no, it simply means that a function needs not necessarily to return a value. It can achieve the desired results without using return. For example:

string nameWithReturn(string name) // when function used with return
{
return name;
}

void nameWithoutReturn(string name) // when same thing is acheieved //without return
{
cout << name;
}

Both functions will output exactly the same thing, the only difference is that the latter one returns nothing. So the return valt of the first one can be saved in a variable directly but you can't do this for the latter one.
