Variable names are used so the code is readable. When the code is compiled to machine languages, it no longer uses the variable names to understand it's operations...sometimes variable names are kept as metadata to help debug but the computer does not need them to execute the program...they are for us so we can easily understand what we are doing.
Identifiers or symbols are the names you supply for variables,type,function and labels.Identifiers names must differ in spelling and case from any keyword.you cannot use keyword as an identifier.you can create an identifier by specifying it in the declaration of a variable,type or function.
False. Most C++ programmers use uppercase for macros (precompiler definitions), making them less likely to be confused with actual variables, constants or functions in the C++ source code. Macros are not actually part of the C++ language because the compiler never sees them, but they allow the precompiler to perform preprocessing tasks that would be difficult or impossible to accomplish with C++ code alone.
Any name that is not a reserved word can be a legal variable, function or type name. All names must be alphanumeric, but they cannot begin with a digit. The C++ standard recommends that all user-defined names be written entirely in lower case with underscores for spaces. Some programmers prefer 'camel case' (such as PrintObject and MaxNumber), which was a popular convention amongst the Pascal programming community, however print_object and max_number are the C++ conventions. Names in all caps are typically reserved for macro definitions (which is effectively a separate language from C++ itself), while names with leading underscores should generally be avoided as this convention is utilised extensively within the standard library.
create a program that can input 100 names
No.
The m prefix in variable names in Python programming is a convention used to indicate that the variable is meant to be treated as a private or internal variable within a class or module. It helps to differentiate between public and private variables, making the code more organized and easier to understand for other programmers.

You can use the exec statement in Python to create variables from strings. For example, exec("a = 100") creates a variable named a with a value of 100.
In most programming languages, variable names cannot start with a number. Variable names must start with a letter, underscore (_), or dollar sign ($). This rule is in place to differentiate variable names from numeric literals.
Variable-names aren't to be declared.
Well, firstly, all PHP variable names begin with the dollar sign. After that...PHP variable names must begin with either a letter or an underscore ( _ )PHP variable names can only contain letters, numbers, and underscores.A variable cannot contain spaces. Therefore variable names using more than one word should be separated using an underscore or camel cased. e.g. $multiple_word_variable_name OR $multipleWordVariableName.

There's several ways: 1) You can put square brackets on the end of a variable to create an array key inside that variable: $names['first'] = "john" $names['last'] = "smith" 2) You can use the array function: $names = array('first' => "john", 'last => "smith"); a lot of people set this function out like this: $names = array( 'first' => "john", 'last' => "smith" ); it makes it easier to read hope this helps
It has these names: Manipulated variable, controlled variable, and independent variable. Hope it helps - Roxas riku
When declaring a variable, don't use short and cryptic names such as 'x'. Use descriptive names for the variable, such as 'accumulator'. Also, don't declare more than one variable on the same line. You can, but it will help take some errors away from your code.
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
