Consider the following two function prototypes:

void Func1(int&, int&); int Func2(double, double);


-I need help completing the following C++ user-defined function Func3
-which prompts and gets an integer for the variable Option from user.
-Func1 should be called when the value of Option is 1,
- Func2 should be called when the value Option is 2, the message "Wrong Selection. " should be displayed if the user had entered anything other than 1 or 2.


C++ Syntax (Toggle Plain Text) 
  1. int Func3 ()
  2. {    
  3.      int Option;
  4.      int   A = 2;   
  5.      int B = 3;   
  6.      double C = 2.5;         
  7.      double D = 3.5;
  8.      cout << " Enter your select: ";
  9.      cin >> Option;
  10.  
  11.  
  12. }

pseudo-code follows:

....
get option
while option isn't 1 or 2
display "Bad option selection, re-enter it: "
get option
end while
if option is 1
call func1 with A and B
if option is 2
call func2 with C and D
