What is wrong with my C++ program? i am doing funtions and i am getting to errors that i don't know how to fix

this is my code:


#include %26lt;iostream%26gt;


#include %26lt;string%26gt;


#include %26lt;iomanip%26gt;





using std::cout;


using std::cin;


using std::endl;


using std::string;


using std::setprecision;


using std::fixed;





//function prototypes


void getInput(string %26amp;, double %26amp;);


void calcFedTaxes(const double %26amp;, const double %26amp;, double %26amp;, double %26amp;, double %26amp;);


void calcNetPay(double %26amp;, double %26amp;, double %26amp;, double %26amp;);


void displayInfo(string %26amp;, double %26amp;, double %26amp;, double %26amp;);





int main()


{


//declare constants and variables


const double FWT_RATE = .2;


const double FICA_RATE = .08;


string name = "";


double salary = 0.0;


double fwtTax = 0.0;


double ficaTax = 0.0;


double netPay = 0.0;





//call funtions to get input


//calculate and display taxes and net pay


getInput(name, salary);


calcFedTaxes(FWT_RATE, FICA_RATE, salary, fwtTax, ficaTax);


calcNetPay(netPay, salary, ficaTax, fwtTax);


displayInfo(name, fwtTax, ficaTax, netPay);





return 0;


} //end of main function

In calcFedTaxes, you're mixing const doubles with doubles between your declaration (line 14)





void calcFedTaxes(const double %26amp;, const double %26amp;, double %26amp;, double %26amp;, double %26amp;);








and in your implementation (line 50)





void calcFedTaxes(double %26amp;FWT_RATE, double %26amp;FICA_RATE, double %26amp;salary, double %26amp;fwtTax, double %26amp;ficaTax)
