You can give alias names to a struct: typedef struct Person { char name[32]; int age; } Person; Person person; Compared to the traditional way of declaring structs, programmers wouldn't need to have struct every time they declare an instance of that struct. Note that the name Pers...

Build a text report showing the main classification metrics, including the precision and recall, f1-score (the harmonic mean of precision and recall) and support (the number of observations of that class in the training set). Example from sklearn docs: from sklearn.metrics import classification_re...

If-statements can be expressions: val str = if (condition) "Condition met!" else "Condition not met!" Note that the else-branch is not optional if the if-statement is used as an expression. This can also been done with a multi-line variant with curly brackets and multiple el...

Properties can be set when an object is instantiated. var redCar = new Car { Wheels = 2, Year = 2016, Color = Color.Red };

Explicit casting operators can be used to perform conversions of numeric types, even though they don't extend or implement one another. double value = -1.1; int number = (int) value; Note that in cases where the destination type has less precision than the original type, precision will be lost....
