Thread: Stuck on project C#

I'm stack in this project, I need help figuring out how to write these formulas correctly in C#:

Women Thirty Years and Younger

hips + (.80 x thigh) – (2 x calf) – wrist = % body fat

Women over Thirty

hips + thigh – (2 x calf) – wrist = % body fat

Men Thirty Years and Younger

waist + (1/2 hips) – (3 x forearm) – wrist = % body fat

Men over Thirty

waist + (1/2 hips) – (2.7 x forearm) – wrist = % body fat

Men

Lean Body Mass (pounds) ÷ 0.85 = correct weight to be 15% fat

Women

Lean Body Mass (pounds) ÷ 0.78 = correct weight to be 22% fat


I have attached a screenshots please take a look.

Pictures of your UI are fine.

Pictures of your code are useless.
Paste code between [code][/code] tags so we can meaningfully quote and refer to it.

> waist + (1/2 hips) – (3 x forearm) – wrist = % body fat
Like say

Code:

percent_body_fat = waist + (0.5 * hips) - ( 3 * forearm ) - wrist;

> Okay, what else is needed to make the application run correctly ?
Some effort on your part.

You already have an example of how to check for one of the radio buttons.

In pseudo code, it's

Code:

if ( male ) {
  if ( over_thirty ) {
  } else if (  thirty_and_under )
  }
} else if ( female ) {
  if ( over_thirty ) {
  } else if (  thirty_and_under )
  }
}

Each of those 4 cases calculates a percent_body_fat using the formulae you've been given.

Now show some code.

Slow down and test as you go.

Don't try and write the whole thing, then wonder why it's full of errors and/or doesn't work.

Code:

if ( male ) {
  if ( over_thirty ) {
  } else if (  thirty_and_under )
  }
} else if ( female ) {
  if ( over_thirty ) {
  } else if (  thirty_and_under )
  }
}

Without filling in any calculations, make sure this logic actually compiles before trying to do anything else.

Then add one calculation like so.

Code:

if ( male ) {
  if ( over_thirty ) {
    percentfat = // whichever it is.
  } else if (  thirty_and_under )
  }
} else if ( female ) {
  if ( over_thirty ) {
  } else if (  thirty_and_under )
  }
}

// Then however you write to your results text field
result = "Fat = " + ToString.to_string();

Check that when you select male over 30 in your radio buttons and type in some values into your other dialogs, that the final result is OK when you press calculate.

Then do the same for the other calculations.
