Hello all C++ noob here. Ok so here is my little problem. I am converting centimeters to inches(To the nearest inch) but I do not know how to do it. I have tried but so far no luck. Any help would be appriates as its done this Friday. Here is my source. This is do wiht Dev-C++.

// Take a number in Centimeters and convert it to yards, feet, and inches
#include <iostream>
using namespace std;

// Declare constant variables
const int yard = 36;
const int foot = 12;
const double centimeters_to_inches = 0.393700787;

int main()
{
// Declare some varibales
double centimeters;
int yards, feet, inches, total_inches;


// Ask for a number in centimeters
cout << "Please enter a number in centimeters: ";
cin >> centimeters;

// Convert centimeters to inches
total_inches = centimeters * centimeters_to_inches;

// Calculate how many yards are in the total inches
yards = total_inches / yard;

// Find the the remainder of yards
total_inches = (total_inches % yard);

// Calculate how many feet are in the remainder
feet = total_inches / foot;

// Find the reaminder of feet
total_inches = (total_inches % foot);

// Calulate how many inches are in the remainder
inches = total_inches;

cout << "There are " << yards << " yard(s), "
<< feet << " feet(foot), "
<< inches << " inch(es)" << endl;

system("PAUSE");
return 0;
}

Do you want to round down, or round up?

Look at the floor() and ceil() functions in math.h.

floor( totalInches) will return the largest integer that is smaller than totalInches.
ceil( totalInches) will return the smallest integer that is larger than totalInches.

I hope this helps

I don't mean to be a smart-ass, but did you not look for a rounding function... like... round()?

man 3 round

Also in math.h.

And be sure to apply any of those functions to the centimeters * centimeters_to_inches calculation, not the total_inches value, since that value has been declared as an int, and will have been truncated to an int by the automatic type conversion. (You may, in fact, get a compiler warning for setting an int to a double.)

<Edit>You might also want to see if your compiler supports the decimal data type.</Edit>

Thank you for all the help guys got the program to work right. A+ here i come. lol

Hey, I thought the guidelines here said "No homework problems!"

The point of the homework is to teach you how to find the answers on your own, in the instructional materials you should be studying. And, of course, the point in studying is to learn everything else available in you study material.

nope they sayAll I see in this thread is help/hints not solutions.
