SCHEME

 

·         Readability-

 

Scheme is a programming language with a very few numbers of rules. Since scheme had a smaller number of constructs it was easy for the programmers to read and understand the code which increased the readability of the code. Also, scheme used let, lambda, define, if, cons, list, and (), which made the developer to read and understand the code easily. Scheme allows objects such as atoms and lists. Scheme is a language which is known for the simple syntax. By using all these we can conclude saying that scheme is a readable language.

 

·         Writability-

 

Scheme allows lambda functions and procedure which increased the writability of the language. Also, scheme has expressivity which makes the developer easier to develop programs in the language. Furthermore, scheme uses the block structure in the program, which increases the readability and writability of the language. Scheme uses () for differentiating the code which also eliminates dangling else problem.

 

·         Reliability-

 

Scheme as a programming language doesn’t allow exception handing and aliasing, which negatively impact the programming language. The reliability of the language becomes questionable due to the above-mentioned reasons.
