Question

Example of non-regularity of c++ or phyton. You should provide an example to each one of the following categories: Generality, Orthogonality, and Uniformity. That is, you will give total of three examples and explain why...

Answer 1

Example of non-regularity of c++ :--

• Efficiency of targeted code is very important for any language design. the language should be in such a way that translator can generate executable code.
• Example of non-regularity of c++ is :- static variables and Classes in c++.
• When the classes of c++ is not used with the advanced object oriented features then it is not very different in memory consumption than a simple C struct.

Orthogonality --

• This feature discourages the avodance of special features due to being context independent.
• In c++ , all data types values returned from function excepting array types.
• The c++ require the variable to be declared somewhere in the same block of code before they are used in.
• for example --
• int x = 9, y = 10;
• Y++ ;
• In above example would be overloading a comparision operator in c++ . it will not be able to identify weather the two elements are equal or not.

Generality --

• The generality avoid special cases in use of construct.
• The generality combines related construct into single general construct.
• Example int z = 4; u = 9;
• u ++ ;
• The above example of orthogonality can overload the operators.

Uniformity --

• Semicolon is necessary after a class definition.
• Example -- class A ( );
• int a();
• the uniformity was forced to allow c++ to be compatible with C.
• the other example of uniformity can be "operators &" (bitwise and) , "&& operator" (logical and). these both provide different results but looks very similar.
