compiling

[poohbear]

so the code compiles but as soon as i build it and crashes. i use geany for this. can someone explain what is happening

  employee.cpp
#include<iostream>
#include<string>
#include<iomanip>
#include "employee.h"

bool Employee::setName(string name)
{

    if(name=="")

    return false;

   this->name = name;

return true;

}
bool Employee::setRate(double rate)
{

    if(rate<0)

    return false;

    this->rate = rate;

    return true;

}

bool Employee::setHours(double hours){

    if(hours<0)

return false;

    this->hours = hours;

return true;

}

double Employee::getPay(){

double pay = hours*rate;

    if(hours>40)

pay += (hours-40)*rate*0.5;

return pay;

}

double Employee:: getHours(){

return hours;

}

double Employee:: getRate(){

return rate;

}

string Employee:: getName(){

return name;

}

employee.h
//header file
#include<iostream>
#include<string>
#include<iomanip>

using  namespace std;

class Employee

{

public:

bool setName(string);


bool setRate(double) ;


bool setHours(double);

   

   

double getPay();

double getHours();


double getRate();


string getName();



private:

string name;

double hours;

double rate;

};
driver.cpp
//where main is

#include "employee.h"
#include<iostream>
#include<string>
#include<iomanip>

int main()

{

string name;

double hours, rate;

Employee *emp = new Employee;

char another;

do{

cout<<"Enter employee's name: ";

while(1){

getline(cin, name);

if(emp->setName(name))

break;

cout<<"Name cannot be blank, re-enter: ";

}

cout<<"Enter hours worked: ";

while(1)
{

    cin>>hours;

    if(emp->setHours(hours))

break;

cout<<"Hours must be positive. re-enter: ";

}

cout<<"Enter hourly rate: ";

while(1)
{

    cin>>rate;

    if(emp->setRate(rate))

break;

cout<<"Hourly rate must be positive, re-enter: ";

}

cout<<setprecision(2)<<fixed;

cout<<"\n\nGross pay for "<<emp->getName()<<": $"<<emp->getPay()<<endl<<endl;

cout<<"Another employee? (Y/N): ";

cin>>another;

//for buffering

getline(cin, name);

}
while(another!='Y' || another!='y');

cout<<"Press any key to continue";

cin>>another;

return 0;

}

It crashes before you have even entered any input? Is there an error message?

[poohbear]

That is a linker error. You don't compile/link the employee.cpp

g++ -Wall -Wextra -o driver driver.cpp employee.cpp

[poohbear]

thank you!

[Peter87]

It's not compiling the employee.cpp file for some reason. Have you tried creating a "project" and added all the files to the same project? I also use Geany but I haven't tried to use the project feature in a very long time so I don't remember if you had to do anything special to make it work correctly. Things might have changed since then anyway.

[poohbear]

at peter . i tried that right now with something else and it doesnt work.

[Peter87]

Well, it seems like you are supposed to set it up yourself, using a makefile or whatever you prefer.
