going crazy- codewarrior debugging, someone help me please.
this code for school is really really bugging me. these errors are confusing the hell out of me. someone please give me some help!! i use codewarrior learning edition.. not sure what version though, anyway here it is:
// This program is used to compute the amount due from a
// customer of the Gas-N-Clean Service Station. Constants
// are used for gasoline prices. Note the use of nested
// selection to compute the cost of the car wash.

#include <iostream.h>
#include <iomanip.h>

const double PLUS_PRICE = 1.199;
const double SUPER_PRICE = 1.289;
// Function: printHeading
// Prints a signon message for program

// Function: getData
// Get information interactively from the keyboard.

// a choice as to whether a car wash is desired

// Computes the gas cost, wash cost, and total cost
// Inputs: number of gallons, gas type, wash option

i just need the errors debugged, thats all. someone, anyone!
