After compiling the following program and getting no errors, I tried to build
an executable and received external errors. Can anyone help me?
//T7AppE08.cpp - displays employee's name, FWT, FICA tax, and net pay
#include <iostream>
#include <string>
using namespace std;
//function prototypes
void getInput(string, float&);
float calcFwt(float, float);
float calcFica(float, float);
float calcNetPay(float, float, float);
void displayInfo(string, float, float, float, float);
int main()
{
const float FWT_RATE = float(.2);
const float FICA_RATE = float(.08);
string name = "";
float salary = 0.0;
float fwtTax = 0.0;
float ficaTax = 0.0;
float netPay = 0.0;
//enter input items
getInput(name, salary);
//calculate taxes
calcFwt(salary, FWT_RATE);
calcFica(salary, FICA_RATE);
//calculate net pay
calcNetPay(salary, fwtTax, ficaTax);
//display name, gross, taxes, and net
displayInfo(name, salary, fwtTax, ficaTax, netPay);
return 0;
} //end of main function
//*****program-defined functions*****
void getInput(string name, float salary)
{
cout << "Enter employee name: ";
getline(cin, name);
cout << "Enter weekly salary: ";
cin >> salary;
} //end of getInput function
float calcFwt(float salary, const float FWT_RATE, float fwtTax)
{
fwtTax = salary * FWT_RATE;
return fwtTax;
} //end of calcFwt function
float calcFica(float &salary, const float FICA_RATE, float ficaTax)
{
ficaTax = salary * FICA_RATE;
return ficaTax;
} //end of calcFica function
float calcNetPay(float salary, float fwtTax, float ficaTax, float netPay)
{

return netPay;
} //end of calcNetPay function
void displayInfo(string &name, float salary, float fwtTax, float ficaTax,
