Challenge: Condensed, but does it make sense?

Objective-C Programming (2nd Edition) 10. Pass-By-Reference

I’m seeing several different challenge discussions on this, so I thought I’d throw my solution out there. I got the output to read feet = 9, inches = 10.12, which is what it should, but I skipped the whole “void metersToFeetAndInches” part that I saw in others. Should I be including this and writing it that way or does this condensed version make sense?

[code]#include <stdio.h>
#include <math.h>

int main(int argc, const char * argv[]) {
//Use modf() instead of floor() and subtraction to convert metersToFeetAndInches()

//Convert meters into feet
double meters = 3.0;
double rawFeet = meters * 3.281;
double feetPart;
double inchesPart;

//Break rawFeet into feet and inches w/ modf()
inchesPart = 12 * modf(rawFeet, &feetPart);

//Find the value of feet + inches
printf(“feet = %.0f, inches = %.2f\n”, feetPart, inchesPart);
}[/code]

The challenge is not asking you to write the shortest code possible, but asking you to demonstrate whether you understand the concept of passing arguments by reference to a function, and to demonstrate how to return information back to the caller in those arguments.
