Many languages distinguish between uppercase and lowecase letters in user-defined names what are the pros and cons of this design decision?
In computer programming, many languages distinguish between uppercase and lowercase letters in user defined variables. This is an advantage because it allows users to tell the difference between variables based on whether they are uppercase or not. It is a disadvantage because forgetting to change a letter to the proper case will result in an error when the program runs.
What are the characteristic features of the procedural programming languages?
- Easy location of errors in the program - Easy understanding of the program code - Execution of the pogram is faster - The program becomes neat (commenting the program codes) Jimmy C. Malusi (jimmy20clinton@live.com)
How many memory variables can be defined in Foxpro?
The same as in other programming languages. A place to store a value. A variable may be of different types, including logical, string, numeric, or date. Here is an example that uses a variable: x = 5 ? "The square root of", x, " is ", sqrt(x). In FoxPro, it isn't necessary to declare variables. It is safer, though, in order to avoid conflicts between different modules, to declare the variable (usually with the LOCAL keyword if you use Visual FoxPro, or PRIVATE if you use the old FoxPro 1.x or 2.x). All variables are of a type which in some languages is called "variant", that is, the type can change at runtime.
Difference between procedural programming and modular programming?
Procedural programming is a computer programming technique in which the program is divided into modules like function or subroutine or procedure or subprograms, where as ... "Modular Programming" is the act of designing and writing programs as interactions among functions that each perform a single well-defined function, and which have minimal side-effect interaction between them. Put differently, the content of each function is cohesive, and there is low coupling between functions as happens in procedural programming.
What is object oriented paradigm in java?
the concept of "pure" in object orientation is a little subjective and not quite well defined in practice, but there are pure object oriented programming languages. The principles of object orientation on the other hand are well defined. Programming languages are quite nested in complicated materials, and it is hard to say that everything must be an object, since all formal systems need primitives. How can you define an object without the notion of an object as a definition? This all comes down to type theory, and one can't define everything as "something" without knowing the "something". With this, Java is not actually a pure object oriented programming language since it needs primitives. The only way you can yield a pure programming language with no primitives is not even having the notion of defining concrete terms in a programming language since it doesn't have primitives in it.Smalltalk is an example of a pure programming language. With this, I can't exactly answer the question since you've presented two OO programming languages, neither of which is "pure".-Fabianski BenjaminIndia
What are the classification of programming languages?
Programming languages, like human languages, are defined through the use of syntactic and semantic rules, to determine structure and meaning respectively. Thousands of different programming languages have been created, and new languages are created every year.

Why do you write programming languages?
To perform Specific Tasks Using Mathematical, Logical and some other specail inbuilt functions and user defined functions.
Is addition operation is allowed on string?
Not in the general sense of addition. However, certain programming languages use the syntax stringResult = stringone + stringtwo to mean concatenation. In the above case, if stringone contained "Good " and stringtwo contained "Day", then stringResult would yield "Good Day" provided of course that the three string variables are properly defined.
What is a formal language?
A formal language is a precise and well-defined system of symbols and rules used to represent and manipulate information. It is typically used in areas such as mathematics, computer science, and linguistics. Examples of formal languages include programming languages, mathematical notation, and formal grammars.
In c programming is main predefined or user defined?
main is predeclared and user defined.

What is a conceptual variable?
A conceptual variable is an abstract idea or construct that is used in research to represent a theoretical concept that cannot be directly observed or measured. It often serves as an underlying factor or theoretical explanation for observed phenomena in a research study.
What are strongly typed languages?
Strongly typed languages enforce strict type checking at compile time, ensuring that variables are used in a way that is consistent with their defined types. This can help catch errors early in the development process and improve code reliability. Examples of strongly typed languages include Java, C++, and Swift.
