Re: Returning

double MPG ( double sizeoftank, double number of milest, double gasleftintank)
{
double numberofmilest;

numberofmilest=sizeoftank/gasleftintank;
return numberofmilest;
}

Done
I have not run the function in a program, its the freaking math of this thats pissing me off, this shit is frustrating

i switched the bolded statement around if miles/gallon will yeild mpg then I guess this is right...let me rephrase that I hope this is right....

Re: Returning

Ok, I can see where you are confused and I apologise accordingly. I re-read your initial first post and I skipped the bits about the information to be input being 1. size of tank, 2. gallons left and 3. miles travelled. I assumed (lesson never assume) that gallons used was inputted directly. In that regard, yes, there are three (not two as I previously mentioned) arguments to be passed into the function. In the function simply deduct gallons left from size of tank and that equals gallons used. From there it's a straight out mpg calculation.

Ok, here's the formula:

miles travelled / (size of tank - gallons left) = mpg.

mpg is miles per gallon.

miles : 1000
size (gallons) : 60
left (gallons) : 10
1000 / (60-10) = 20 mpg.

  1. double MPG ( double sizeoftank, double numberofmilest, double gasleftintank)
  2. {
  3.  
  4.  
  5. mpg=numberofmilest/(sizeoftank-gasleftintank);
  6. return mpg;
  7. }
