sigh a little help please

[Sublyminal]

Okay, I'm having a little issue out of my latest program, which yes is a homework assignment. I have the code written, but, for some reason it's not doing like what my professor requires.

This is the output I get from the code..

Number of rooms
3
28 17 20.3
28 17 4.82117-e41

It's supposed to output like this...

3 (For the count)
23 13 18.20 //length, width, and cost per square foot
28 15 20.60
14 11 25.53


Can one of you gurus help me out and tell me what the heck I'm doing wrong? thanks!

#include <iostream>
#include <iomanip>


using namespace std;

void getdata (int&, int&, float&);
float InstalledPrice (int , int, float );
float totalprice (float);
void printdata (int , int, float);



int main()
{

    int length, width, count, i;
    float installation, costpersqfoot, price;

    cout << "Enter the amount of rooms.\n";
    cin >> i;

    for(count = i; count != 0; count --)
    { //beginning of for loop
        getdata (length, width, costpersqfoot);
        installation = InstalledPrice (length, width, costpersqfoot);
        price = totalprice (installation);
        printdata (length, width, price);

    } //end of for loop

}

void getdata(int & length, int & width, float & costpersqft)
{
    cin >> length >> width >> costpersqft;
}

float InstalledPrice (int length, int width, float costpersqfoot)
{
    const float LABOR_COST = 0.35;
    float sqfoot, installation;
    sqfoot = length * width;
    installation = (costpersqfoot * sqfoot) + (LABOR_COST * sqfoot);
}

float totalprice(float installation)
{
    const float TAX_RATE = 0.05;
    float price;
    return(installation * TAX_RATE) + installation;
}

void printdata(int length, int width, float price)
{
    cout << length << " " << width << " " << price << endl;
}

After line 44, you should return a value.

[Sublyminal]

return a value as in return 0; or return as in what I have on line 51? I know it's something simple but for some reason I can't figure it out. Been working on this code for about 6 hrs now. ><

[wildblue]

I think you mean to return the value you've calculated at line 44? The value that you then mean to send to the totalprice function at line 27.

[Sublyminal]

Okay, lets try to add that and see what we come up with. I'll try to add the return to that function call.

[Sublyminal]

I believe that, that may have been my issue. I knew it was something easy and my dumbass was overlooking it the whole time.

[PCrumley48]

Looks to me like you could either

return installation; after line 44,

or

return (costpersqfoot * sqfoot) +(. . . etc. ); as line 44.

In the second case you don't need to declare or calculate installation since it's what you're returning.

[Sublyminal]

Now I have to get my math right because it's def not adding up to the right price.

[jlb]

What exactly are you inputting into your program?

[Sublyminal]

@jib nevermind I'm a dumbass it's adding everything correctly. I forgot I was adding the square footage of 3 rooms instead of 1 room.

thanks to all for the push in the right direction.
