Your function wants a value, but your not sending it one.
showBill;
should be
showBill (somevalue);
How do I get it to display the functions body. Ex "Your total is: "<< chg<<<endl; from showBills body?
What do you mean by display the function's body? The code will be run when you call the function.
It should work like this.
