Homework Function Help.

[Poeticsoul44]

Below i Have 3 different functions I wrote for a homework assignment. I'm not sure what is wrong with them. Any help would be GREATLY Appreciated.

void airfare(double &airfareCost, double &airfareAllowd)
{
Cout<< "Enter cost of airefare"<<endl;
cin>> airfareCost<<endl;
airfareAllowd=airfareCost;

}


void milage(int miles, double &milageCost, double&milageAllowd)
{
cout<< "Enter cost of airefare"<<endl;
cin>> milageCost<<endl;
cout<<"Enter number of miles"<<endl;
cin<<miles<<endl;
milageAllowed= miles* 0.38 ;
}


Void taxi(int taxiDays, double &taxiCost, double&taxiAllowd)
{
cout<< "Enter number of days travelled"<< endl;
cin>>taxiDays<<endl;
cout<< "Enter Total cost of Taxi"<<endl;
cin>>taxiCost<<endl;
taxiAllowed=taxiDays * 10 ;
}

C++ is case sensitive.

Pay attention to the direction when using << and >>.

Use whitespace for improved readability.

[Poeticsoul44]

So I messed up on << and >>? Was that the only thing?

I don't do a lot of console programming, but I'm not sure sending endl to cin makes any sense.

I also mentioned that C++ is case sensitive.

Yea. I caught the error..But theres something else wrong with it because they wont compile for some reason.

Yea. I caught the error..But theres something else wrong with it because they wont compile for some reason.

There are lots of errors. I already pointed out the category. What does the compiler say?

[Poeticsoul44]

the first gives the following errors:
air.cpp: In function &#226;void airfare(double&, double&)&#226;:
air.cpp:3: error: &#226;cout&#226; was not declared in this scope
air.cpp:3: error: &#226;endl&#226; was not declared in this scope
air.cpp:4: error: &#226;cin&#226; was not declared in this scope
air.cpp:5: error: &#226;airefareAllowed&#226; was not declared in this scope
air.cpp:5: error: &#226;airefareCost&#226; was not declared in this scope

The second funtion i get these errors:
miles.cpp: In function &#226;void milage(int, double&, double&)&#226;:
miles.cpp:3: error: &#226;cout&#226; was not declared in this scope
miles.cpp:3: error: &#226;endl&#226; was not declared in this scope
miles.cpp:4: error: &#226;cin&#226; was not declared in this scope

And the third gives me these errors:
taxi.cpp: In function &#226;void taxi(int, double&, double&)&#226;:
taxi.cpp:3: error: &#226;cout&#226; was not declared in this scope
taxi.cpp:3: error: &#226;endl&#226; was not declared in this scope
taxi.cpp:4: error: &#226;cin&#226; was not declared in this scope

[GCDEF]

Did you include iostream?

[Poeticsoul44]

I just did and i get these errors for the first:
air.cpp: In function &#226;void airfare(double&, double&)&#226;:
air.cpp:4: error: &#226;cout&#226; was not declared in this scope
air.cpp:4: error: &#226;endl&#226; was not declared in this scope
air.cpp:5: error: &#226;cin&#226; was not declared in this scope
air.cpp:6: error: &#226;airefareAllowed&#226; was not declared in this scope
air.cpp:6: error: &#226;airefareCost&#226; was not declared in this scope


For the second i get:
miles.cpp: In function &#226;void milage(int, double&, double&)&#226;:
miles.cpp:4: error: &#226;cout&#226; was not declared in this scope
miles.cpp:4: error: &#226;endl&#226; was not declared in this scope
miles.cpp:5: error: &#226;cin&#226; was not declared in this scope

and the third i get:
taxi.cpp: In function &#226;void taxi(int, double&, double&)&#226;:
taxi.cpp:4: error: &#226;cout&#226; was not declared in this scope
taxi.cpp:4: error: &#226;endl&#226; was not declared in this scope
taxi.cpp:5: error: &#226;cin&#226; was not declared in this scope

[GCDEF]

Post your entire code as it is now.

[Poeticsoul44]

First function code:
#include <iostream>
void airfare(double &airfareCost, double & airfareAllowed)
{
cout<< "Enter cost of airfare"<<endl;
cin>>airfareCost;
airefareAllowed=airefareCost;
}

2nd:
#include <iostream>
void milage(int miles,double &milageCost, double&milageAllowed)
{
cout<<"Enter cost of milage"<<endl;
cin>>milageCost;
cout<<"enter number of mile"<<endl;
cin>>miles;
milageAllowed= miles * 0.38;
}

3rd:
#include <iostream>
void taxi(int taxiDays, double &taxiCost, double&taxiAllowed)
{
cout<< "Enter number of days travelled"<<endl;
cin>>taxiDays;
cout<<"enter total cost of taxi"<<endl;
cin>>taxiCost;
taxiAllowed=taxiDays *10;
}

You forgot to put

using namespace std;

at the top.

And there's no need to #include a file more than once in a given cpp.

[Poeticsoul44]

I just included "using namespace std;" and get these errors:
1st:
air.cpp: In function &#226;void airfare(double&, double&)&#226;:
air.cpp:7: error: &#226;airefareAllowed&#226; was not declared in this scope
air.cpp:7: error: &#226;airefareCost&#226; was not declared in this scope
2nd:
miles.cpp: In function &#226;void milage(int, double&, double&)&#226;:
miles.cpp:4: error: &#226;cout&#226; was not declared in this scope
miles.cpp:4: error: &#226;endl&#226; was not declared in this scope
miles.cpp:5: error: &#226;cin&#226; was not declared in this scope
3rd:
/usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/crt1.o: In function `_start':
(.text+0x20): undefined reference to `main'
collect2: ld returned 1 exit status

You're going to have to give us more to work with if you want help sorting this out.....

What all do you want to know?
