All names must be composed from some combination of letters, digits and underscores. A name cannot begin with a leading digit but it must contain at least one letter. The only symbols that can physically separate one name from another are the binary operator symbols and semi-colons. Note that whitespace characters are only of relevance when a name identifies a type:
int x; // int is a type, x is a name; whitespace is essential here
int y, z; // comma-separated list of names; all whitespace within the list is ignored
x = y + z; // binary operators '=' and '+' separate the names (all whitespace is ignored)

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.
What are variable start the us for naming variyable?
In the U.S., variable names in programming typically follow specific conventions: they must start with a letter (A-Z or a-z) or an underscore (_), and they cannot begin with a digit. After the first character, variables can include letters, digits (0-9), and underscores. Additionally, variable names are case-sensitive, meaning "Variable" and "variable" would be considered different identifiers. It's also a best practice to use descriptive names that convey the purpose of the variable.
