Variable names should show what data the variable holds so others reading your code will understand it. For example, a variable holding the age of a user should be called "age" or "user_age", or something similar.

What do the percent signs in SystemRoot represent?
Substituting environment variable valuesTo enable the substitution of variable values at the command line or in scripts, enclose the variable name in percent signs (that is, %variablename%). By using percent signs, you ensure that Cmd.exe references the variable values instead of making a literal comparison. After you define variable values for a variable name, enclose the variable name in percent signs. Cmd.exe searches for all instances of the variable name and replaces it with the defined variable value. For example, if you create a script that contains different values (for example, user names) and you want to define the USERNAME environment variable for each user with these values, you can write one script using the variable USERNAME enclosed in percent signs. When you run this script, Cmd.exe replaces %USERNAME% with the variable values, which eliminates the need to perform this task manually for each user. Variable substitution is not recursive. Cmd.exe checks variables once. For more information about variable substitution, see For and CallFrom the above Technet description, the % signs are used to ensure that "cmd.exe" does not literally use the term "systemroot" and references the systemroot variable correctly (So therefore %systemroot% is recognised correctly as the C:\ drive, if C:\ is your systemroot).
What is the scope of c?
Describe the concept of Scope :Incomputer programming, ascopeis the context within acomputer programin which avariable nameor other identifier is valid and can be used, or within which adeclarationhas effect. Outside of the scope of a variable name, the variable's value may still be stored, and may even be accessible in some way, but the name does not refer to it; that is, the name is notboundto the variable's storage
How do you declare variables and constants.explain with example?
Depends on the programming language you are using. I will give two simple examples. In Command Prompt and when creating a batch file, you declare a variable by entering the "set" command. You can use different switches to change the type of variable you are declaring. /p makes the variable able to accept user input. /a makes the variable a numerical expression. In Python, you declare a variable just by stating the name of the variable and its value. x = value.
Explain different types of coding style in software engineering?
Meaningful variable names. Always use descriptive and meaningful variable names. Don't worry about the length. Meaningful variable names help other people reading your code understand what is going on. Example: if (a <= = 24) What is a? This is confusing. if (vacationHours <= = 24) See, better. <li>Variable scope indicated by name. Code is easier to read and understand if each variable indicates it's scope. One way to do this is to add prefixes to variable names, for example: Scope = Class member or instance variable: m_hours Scope = Class static variable: s_hours Scope = Parameter passed in a method call: p_hours Scope = local variable to a method: l_hours Regards ~Anoop
