Because the compilers do not allow that, you would get a 'Syntax error' if you tried.
(In FORTH, mind you, variable names can start with digits, for example:
VARIABLE 0A ( declare variable )
10 0A ! ( assign value )
0A @ ( fetch value )
)
it should not start with _ or digit.
A valid variable name must start with a letter (a-z, A-Z) or an underscore (_) and can be followed by letters, digits (0-9), or underscores. It cannot contain spaces, special characters, or begin with a digit. Additionally, variable names should not be a reserved keyword in the programming language being used. It's also a good practice to use descriptive names that convey the purpose of the variable.
No. A variable must not start with a number. B5, however, would be acceptable.
For a start: Q: What is the name of the language? A: It is "C".
In many programming languages, variable names must start with a letter or an underscore because using numbers at the beginning can create ambiguity in parsing the code. If a variable name began with a number, it could be misinterpreted as a numeric literal rather than a variable identifier. This rule helps maintain clarity and consistency in the syntax of the language, allowing the compiler or interpreter to correctly understand the intended operations.
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.
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.

It could be one of two things:Programming using the programming language BASICSimple programs, like the ones that you learn to make when you first start programming, like a hello program.
Visual basic is one of the easiest and best places to start.
you learn how in schoolIf your school doesn't have a programming class, then you can independently learn to program. You should start with an easy programming language, like Ruby or Python. Or, if you don't want to learn a programming language, you can get Game Maker. Game Maker has a drag-and-drop interface and there is an optional programming language included that gives you more power over your games.
C is a low level programming language or it is also called as machine level language as the code written in C is encrypted into machine readable form then it is executed. If you want to learn C programming language in depth then Newtum is a best option to start with. It's C programming online course provides complete knowledge of the all the basic concepts involved in programming. If you are interested, please vivist our website!
