When declaring a variable, you typically need to specify a type (in statically typed languages) or use a keyword like var, let, or const (in languages like JavaScript). The variable name should start with a letter or underscore and can include letters, numbers, and underscores, but no spaces or special characters. Additionally, variable names are case-sensitive and should not conflict with reserved keywords in the programming language.

What is main difference between declaring variable and volatile variable?
In languages like C, declaring a variable "volatile" tells the compiler that it can't assume that the variable is only changed by the program code. If the variable is not declared volatile, sometimes the compiler can make certain optimizations since it can assume that it knows everything about how the variable will be used. When it is declared volatile, the variable may be changed by an external process (for example, it could be connected to an I/O device), so it must always be fetched from memory.
