What are the reasons why programmers still prefer to use C over other languages?
C programmers do. The C programming language doesn’t seem to have an expiration date. It’s closeness to the hardware, great portability and deterministic usage of resources makes it ideal for low level development for such things as operating system kernels and embedded software.
Why C language is so important?
C is highly portable language i.e. code written in one machine can be moved to other which is very important and powerful feature. C supports low level features like bit level programming and direct access to memory using pointer which is very useful for managing resource efficiently.
Why is Haskell so popular for functional programming?
You only care what the program is to compute not how or when it is computed. This makes Haskell a more flexible and easy to use language. Haskell tends to be part of the solution for a problem, not a part of the problem itself. Functions play an important role in functional programming languages.
What is the difference between imperative and functional programming languages?
Programming languages such as C/C++/Java/Python are called imperative programming languages because they consist of sequences of actions. The programmer quite explicitly tells the computer how to perform a task, step-by-step. Functional programming languages work differently. Rather than performing actions in a sequence, they evaluate expressions.
What are the side-effects of using Haskell?
There are no side-effects! This extends to variables as well – variables in Haskell do not vary. This may sound strange if you’re used to imperative programming (where most of the code consists of changing the “contents” of a variable), but it’s really quite natural.
What is a variable in Haskell?
A variable in Haskell is a name that is bound to some value, rather than an abstraction of some low-level concept of a memory cell like in imperative languages. When variables are thought of as short-hands for values (just like they are in mathematics), it makes perfect sense that variable updates are not allowed.
