linker error and combine functions?

Sat, 20 Sep 2008 16:47:54 -0700

I started a program that calculates an employee's weekly gross pay when the user inputs hours worked and hourly pay rate. With what I have so far, it compiles fine, but gives these errors:

on Dev-C++:
message: [Linker error] undefined reference to 'get_pay(float, float)'
Id returned 1 exit status
file: C:\Dev-Cpp\Programs\Makefile.win message: [Build Error][grossPay.exe] Error 1

on Visual Studio 2005:
1>------ Build started: Project: grossPay, Configuration: Debug Win32 ------
1>Linking...
1>grossPay.obj : error LNK2019: unresolved external symbol "void __cdecl get_pay(float,float)"

How do I resolve this linker error? And also, how would I add if/else statements for the following condition? If the employee's weekly gross pay is more than $200 (personal exemption), then the employee pays 12% federal tax and 5% state tax from his taxable income (gross pay - exemption). I'd also like to combine the functions I have so that taxable income, fed tax, and state tax are all calculated in the same function.

Here's what I have:

#include <cstdlib>
#include <iostream>

using namespace std;

void get_pay(float wage, float hours);
float calc_gross_pay(float wage, float hours);
float calc_net(float gross, float deduct);
void print_gross_pay(float);
void print_net(float);

int main(int argc, char *argv[])
{
float wage,hours,gross,deduct,sum;

get_pay(wage, hours);
gross = calc_gross_pay(wage, hours);
sum = calc_net(gross, deduct);
print_gross_pay(gross);
print_net(sum);

system("PAUSE");
return EXIT_SUCCESS;
return 0;
}

void get_pay(float& wage, float& hours)
{
cout << "Enter your hourly wage: ";
cin >> wage;
cout << "Enter your hours worked: ";
cin >> hours;
}

float calc_gross_pay(float wage, float hours)
{
return wage * hours;
}

float calc_net(float gross, float deduct)
{
return gross - deduct;
}

void print_gross_pay(float gross)
{
cout << "Your gross pay is: " << gross;
}

void print_net(float sum)
{
cout << "Your net pay is: " << sum;
}

There's nothing wrong I can see with your program. get_pay is prototyped and the body is provided.

the prototype provided was for
void get_pay(float wage, float hours);
but the definition provided was for
void get_pay(float & wage, float & hours)
{
}
try to add such operator '&' in the prototype

for your if-statement question
my advice is to read any book in C, C++, or even JAVA
if-statements are very similar in these languages

see ya

Thank you for the prototype advice! It worked and I'm making some progress on the if else statements.
