Function Declaration

[epicred]

I'm getting invalid function declaration for compute. It needs to accept two arguments.

//tip.h header file
class  tipCalc
{
       private: 
             double taxRate;
             double cost;
             
       public:
             void compute(double, double);
             void print();
              
                           
};

void tipCalc:compute(double c, double t)
{
     cost = c;
     taxRate = t;
}

void tipCalc::print()
{

     std::cout << cost << std::endl;    
     std::cout << taxRate;  
}



//===============================  tip.cpp file.
#include <iostream>
#include "tip.h"

using namespace std;


int main()
{
    
    tipCalc newTip;
    
    double a;
    double b;
    
    cout << "Please enter the cost of your dinner: ";
    cin >> a;
    cout << "Please enter your tax rate in decimal format: ";
    cin >> b;
    
    newTip.compute(a, b);
    
    
    newTip.print();
    
    
 system("PAUSE");
 return 0;   
    
}

at line 15, you are missing a colon ( : )
