In programming, what does it mean to declare a variable? What is a data type? How do you assign a value to a variable? Are there any special rules you need to follow when coming up with a name for a variable?

A variable in programming is an area in the computer’s memory, which has its name and address, through which it is possible to access data of various types. Declaring a variable requires the programmer to determine its type and name, in some cases – the initial value. The type of a variable often determines the set of rules and functions of a programming language for its processing: arithmetic operations can be performed on numeric ones, conjunction, and disjunction operations on logical ones. One must set the value of a variable using assignment operations, which are usually specified using the “=” sign.

A variable name has a limitation in the number of characters and, as a rule, in the use of unique punctuation characters that have a particular functional meaning for the language, except for underscores, which perform the function of a space, which is not allowed in names. Using the camel case technique, it is better to name variables according to their purpose, which corresponds to an unspoken standard in programming and allows convenient interpretation of the code.
