This is very simple, and is pretty much related to your understanding of the BMI’s formula. The code that suits your requirements would be the following: maxweight = (height**2/10000)*24.9 dif = round(abs(maxweight-weight),2) print(name+”, you have”,dif,”kilograms to go until you reach the maximum normal weight”) This works for both underweight and overweight values, always returning a … Read more

[Solved] Every time I start the project always just writes that ” THIS IS NOT VALID” even if the numbers that I give are right [closed]

You are casting (bool) valid_triangel the address of the function instead of calling it. This will always be non-NULL and the corresponding true branch of the if condition will be executed irregardless of input. (non-issue) I don’t have cs50.h installed so I wrote a quick get_double() to test your code. Removed the declaration of valid_tringel() … Read more

[Solved] How can I use lambdas with methods in C#?

by

you can use an expression bodied method. static double Stirling(long n) => Math.Sqrt((2 * n + 1.0 / 3.0) * Math.PI) * Math.Pow(n, n) / Math.Exp(n); This is only possible when the method executes a single statement, and in this case, we get rid of the return statement. or you can use a Func delegate … Read more

[Solved] Why does Float has a constructor that allows double as an argument while Double doesn’t have a constructor with float as an argument in JAVA?

by

I think you’ve said why in your question, but just for clarity: Double(double) works just fine if you pass it a float, so there’s no need for Double(float). This is because in a constructor invocation (JLS§5.3), a widening primitive conversion (JLS§5.1.2) is allowed. float to double is a widening primitive conversion. But Float(float) would not … Read more

[Solved] Turning a content into a $variable in php

by

You can use \DOMDocument->loadHTML(); Ex: <?php $doc = new \DomDocument(); $doc->loadHTML(‘<div class=”whatever”> Title </div>’); View examples here: http://docs.php.net/manual/en/domdocument.loadhtml.php This is assuming that your source is available to php.
