Is Objective-C strongly typed?

Objective-C is definitely strongly, statically typed. Like C, all variables must be declared and typed (there isn’t even type inference as in other modern, statically typed languages). The compiler generates code based on the type of variables and this type cannot be changed at runtime.

Why is Objective-C so weird?

Among other things, Objective-C lets you do function currying, adding and removing methods from classes at runtime, and reflection. Unless you’ve played with other languages that support these features, like Ruby or Lisp, then this feels really weird.

Why C is not a strongly typed language?

C is statically but weakly typed: The weakly type system allows some freedom for speed improvements and allows to handle the memory at a low level. It is thus perfectly fine to use it when you know what you are doing, for tasks where the memory footprint and speed are important.

What is the difference between C++ and Objective C?

C++ is a middle-level language that is being run on various cross-platform operating systems such as Windows, UNIX, Macintosh OS, etc., whereas Objective C is a general-purpose, object-oriented programming language used by Apple in its operating systems and APIs Cocoa, etc.

Why is C known as strongly typed language?

A programming language that requires a variable to be defined, and the variable it is. For example, C is a strongly typed language. When declaring the variable, you must also specify the variable type. In the following example, the test variable is declared as three variable types.

What prevents C from being strongly typed?

According to statically typed language the compiler can statically assign a correct type to every expression. C does not perform any check at run time and a s par the discussion in strongly typed, we concern that in strongly typed, checks perform at runt-time. Hence, C is prevented from being strongly typed.

What is SpriteKit and SceneKit?

Introduction. SpriteKit and SceneKit are iOS frameworks designed to make it easy for developers to create 2D and 3D assets in casual games. You will achieve this by adding a simple play/pause button and score-keeping functionalities to a 3D SceneKit scene through the use of a 2D SpriteKit-based interface.

What is the difference between strongly typed and weak typed languages?

Strong / weakis about whether the type of a value matters, functionally speaking. In a weakly-typed language, you can take two strings that happen to be filled with digits and perform integer addition on them; in a strongly-typed language, this is an error (unless you cast or convert the values to the correct types first).

What is the difference between strong typing and weak typing?

In a weakly-typed language, you can take two strings that happen to be filled with digits and perform integer addition on them; in a strongly-typed language, this is an error (unless you cast or convert the values to the correct types first). Strong / weak typing is not a black-and-white thing; most languages are neither 100\% strict nor 100\% weak.

Why do people use weak dynamic programming languages?

Weak dynamic programming allows for a pragmatic approach; the language doesn’t get in your way most of the time, but it won’t step in when you’re shooting yourself in the foot either.
