switch ( selection )

break;
case 2:
// codes for menu 2
break;
case 3:
// codes for menu 3
break;
default break;
}

So what do I put for the cases? Do I put the Children, Teenagers, Adults and what about the Male and female for each of them, what happens with those?

How will you know which menu item your user selected? In your code where you display the menu options you need to also display a number, or something, that the user can enter to select the menu item.

like 
1
2
3
4
5
6
7
8
9
 
 children (age 1-12)
 1. Male
 2. Female
Teenagers (Age 13-19)
 3. Male
 4. Female
Adults (Age > 19)
 5. Male
 6. Female


These numbers are the cases' in the switch. When the user enters a number the appropriate case is executed.

eg;
1
2
3
4
5
6
7
8
 
switch ( selection ) 
{
case 1: 
  Mcost = CHILDREN_MALE;
  break;
case 2:
  Mcost = CHILDREN_FEMALE;
  break;



Also: float Mcost-0.0 wont compile, it should be float Mcost = 0.0

How do I make a switch case statement so that I can choose?

With 3 outputs like this:

1
2
3
4
5
 
Enter your age? 48
Enter your gender(m/f)? m
Enter your full name: Barack H Obama
     Hello Mr. Barack H Obama
Your membership fee is 302.50

I'm not sure how to make the age < a number using switch statement?
So far I have something like this:

Help???

You cannot use a switch to check a range. You need if:
1
2
3
4
5
6
 
if(Age < 13)
	cout << "Your membership fee is " << (gender == 'm' ? CHILDREN_MALE : CHILDREN_FEMALE) << "(10% tax is included)" << endl;  
else if(Age < 20)
...
else
...

I was on the other thread too but I need help fast so I posted here as well.
I did my program like this but switch statement is required so how would I incorporate it?

...but switch statement is required...


If you need to switch on the menu, look at my earlier answer above. other than that...

You can only switch on constant values, and you can only test equality, that means you wont be able to switch on the age because you need to test a range (like 13-19).
Your only option left is to switch on the gender.

      else if (age <= 19)
         Mcost = TEENAGERS_MALE;
      else
         Mcost = ADULTS_MALE;

      break;

   case 'F':
   case 'f':

      if  (age <= 12)
         Mcost = CHILDREN_FEMALE;
      else if (age <= 19)
         Mcost = TEENAGERS_FEMALE;
      else
         Mcost = ADULTS_FEMALE;

      break;
}
