What is the work or doing of the 'return' statement in the function's body ? To where it returns the value ?

Answer 1

Functions are used to perform certain tasks.
If a function is getting input it Should return desired output.
Now, return statements are used exactly for that purpose.

For example

We have a function which add two numbers a and b in C++ language

int add(int a, int b){
return a+b;
}

Here you can see I used return a+b; to feedback output after doing certain operation.

You can use that function like this

int main(){
int answer = add(5, 5);
}
So now answer variable will store addition of 5+5 using return method.

Answer 2

When a function returns a value, at time of the function call we need to store that returned value in any variable.
In my case function was returning int type value so I stored it in int variable answer.
If your function is returning any other data-type you need to use that type of variable to store returned value.
