Question

[C++ Language] Give example of a void type and a double type function. Also show how they work in it

Answer 1

void type function returns no value . Here is an example

void printMessage(){

cout<<"Hello World!";

}

The function printMessage() prints the message "Hello World", it does not return any value and so the return type is mentioned as void

=============================================================================

double type function returns a value whose data type is double. Here is an example :

double average(int a, int b, int c){

return (a+b+c)/3.0;

}

The function average() takes in 3 arguments of int type, the function computes the average of the 3 numbers and return the average value as a double.
