英语变量名词怎么说

In English, a variable is a place holder for a value that can change. In programming, variables are used to store data values that can be manipulated by the program. The name of a variable is called a variable identifier, and it is used to refer to the variable in the program. Variable identifiers can be made up of letters, numbers, and certain symbols, and they usually follow certain naming conventions that are specific to the programming language being used. In general, variable names should be descriptive and meaningful, so that they are easy to understand and use in the program.
