Hello everybody I'm new here so hello and I need help with a looping assignment. This is for my first C++ so any help would be greatly appreciated.
The problems is -- Write a program which converts inches into feet and inches by using loop(s) (while/do-while/for statement(s)). Do NOT use division (/) or mod (%) operations. Receive user's input (original inches) from keyboard.

You can terminate the program after one session. If you work more so that the program repeats the session until the user signals with -1, you will receive a 1 point EXTRA CREDIT --

The output is supposed to look like this -- WELCOME TO THE INCH CONVERTER! --

Enter the original inches: 71
** Equivalent feet/inches: 5 feet, 11 inches **

----- THANK YOU. GOOD BYE! -----


This is my code so far

#include <iostream>
using namespace std;

int main()
{
    cout << "----- WELCOME TO THE INCH CONVERTER! ----- " << endl;

    int inches;


    cout << "Enter the original inches: ";
    cin >> inches;

    int counter;
    counter = 0;

    while (counter < 12)
    {
        if (inches >= 12)
            inches = inches - 12;
            
        //counter ++;
        counter = counter + 2;
    }

    cout << "** Equivalent feet/inches: " <<  foot << ", " << inches << endl;
    cout << "----- THANK YOU.  GOOD BYE! ----- " <<endl;

    //End of the program
    system("pause");
    
    return 0;
}

I am able to display the inches right but for some reason i cant get the feet displayed. Thanks any help would be appreciated.

So what actually happens?

[Splatocaster]

The variable foot is never declared, initialized, or actually used - however you try to output it...

[shreddingdiego]

Well my output is if I enter 71 inches as the original inches i dont get a feet output just the inches output like is displayed below.
-- WELCOME TO THE INCH CONVERTER! --

Enter the original inches: 71
** Equivalent feet/inches: feet, 11 inches **

The number 5 doesn't come out where its supposed to.

Here's what happens when I try to compile your code with MSVC:

yourcode.cpp(26) : error C2065: 'foot' : undeclared identifier

With g++:

yourcode.cpp: In function 'int main()':
yourcode.cpp:26:47: error: 'foot' was not declared in this scope
yourcode.cpp:30:19: error: 'system' was not declared in this scope

What compiler are you using?

[shreddingdiego]

ok so if I declare a foot variable and initialize it how can i get to display the number of feet without using any division. Because I tried already declaring and initializing it but the feet comes out as the wrong answer.

[Alex6788]

I always recommend not using

system("pause");

it's bad for many reasons. Instead use

cin.get();

and that sometimes won't work if there is already input in the buffer then use

cin.get();
cin.ignore();

Just a tip: conversion from feet to inches can be done with a simple

feet = inches * 0.0833333333;

How were you able to get the correct number of inches show up, without division?

[shreddingdiego]

at the moment i am using visual studio 2010 and your getting that error cause the foot variable wasnt declared yet i missed that still though ive declared it but honestly have no idea where or how to use that to get the right formula for the foot sorry im sure this is a complete noob question but i really do appreciate all your help

that is supposed to be the twist to the problem our professor doesnt want us to use division or mod operators to get the conversion she wants us to use loops and she told us all we were going to need was adding or subtracting and i guess thats the part that is really confusing me.

What do you mean you "missed" that? If you have an error in your code, you won't have a program to run. Yet in your posts, you told us you were running the program and getting unexpected output. Huh?

How did you construct your code? I mean: while (counter < 12) . What is the purpose of counter? Why 12?

counter = counter + 2; Why are you adding 2? Why not 3? Or 1?

If you're having trouble with the program, go through this exercise. Using pen and paper, convert from inches to feet + inches, without dividing. For example, if I gave you 100 inches, convert to feet and inches. Write down all the steps you took, and show it to us.

Quite easy to fix, but what a mess eh?

#include <iostream>
using namespace std;

int main()
{
    cout << "----- WELCOME TO THE INCH CONVERTER! ----- " << endl;

    int inches;


    cout << "Enter the original inches: ";
    cin >> inches;

    int foot; //Replaced EVERY "counter" for "foot"
    foot = 0;

    while (inches >= 12) //Replaced for (inches >= 12) (previously your if condition)
    {
        //Remove if statement (but not the body)
            inches = inches - 12;

        foot ++; //Uncommented this line
        //Removed this one: foot = foot + 2;
    }

    cout << "** Equivalent feet/inches: " <<  foot << ", " << inches << endl;
    cout << "----- THANK YOU.  GOOD BYE! ----- " <<endl;

    system("pause");

    return 0;
}

Study more.

ok thank you very much yeah if you cant tell im new to coding but im trying, but i got the code correct i had a couple of things wrong well a lot of things but thank you all very much for your help i can tell you guys really know what you are doing and if you are interested what the code was to that problem well here it is

#include <iostream>
using namespace std;

int main()
{
    cout << "----- WELCOME TO THE INCH CONVERTER! ----- " << endl;

    int inches; //variable of inches the user will input.
    int feet = 0; // feet is equal to zero because we will increment by 1 in the loop.

    cout << "Enter the original inches: ";
    cin >> inches;

    while (inches >= 12) // loop if the inches is bigger than 12 then the loop will start.
    {
            inches = inches - 12; // upadate the inches.
            
        feet++; // increment variable feet by 1.
    }


    cout << "** Equivalent feet/inches: " << feet << ", " << inches << endl;
    cout << "----- THANK YOU.  GOOD BYE! ----- " <<endl;

    //End of the program
    system("pause");
    
    return 0;
} 

oops i didnt see that by anonymouscodder but thank you so much and yes i know i need a lot of studying but thanks a lot for your help.
