What does strongly typed language mean

Examples of strongly typed languages in existence include Java, Ruby, Smalltalk and Python. In the case of Java, typing errors are detected during compilation Other programming languages, like Ruby, detect typing errors during the runtime. In strongly typed languages, the behavior of operations is more predictable compared to those of weakly typed languages.

The downside is having to declare and type all variables and parameters — though some would argue this is simply good coding. The differentiation between strongly typed languages and weakly typed languages is somewhat blurry. Some of the languages considered strongly typed actually allow concessions that make them weakly typed. Take C , for example. While C requires all its variables to have a defined type, it allows the programmer to disable dynamic type checking. Even Java, considered one of the most strongly typed programming languages, allows objects to be cast to other types.

Answered Aug 10, When we say something is strongly typed we mean that the type of the object is known and available to use. We can say C storngly typed, for example you can not do any airthmatic operation between two different type of variables eg, String vs Integer. What is a dynamic typed language? Dynamically typed languages. A language is dynamically-typed if the type of a variable is checked during run-time.

Dynamic type checking typically results in less optimized code than static type checking. Is C statically typed? In these languages all variables must be declared to be of a specific type. Is Swift a dynamic language? Swift itself, is statically typed. When used with Cocoa, you get access to the objective-c runtime library which gives you the ability to use dynamic classes, messages and all.

This doesn't mean the language itself is dynamically typed. Is C typed? C is not strongly typed. C is a weakly typed language. C is a statically typed language which means each variable's type is determined at compile time and not run-time like Python or JavaScript. It compiles to JavaScript, giving you the benefit of the JavaScript platform plus the intended advantages of types.

C, Go, Java and Swift are great examples of strongly typed languages. You just make use of types implicitly, with the pros and cons that you imagine. Check out my latest YouTube video!
