Why spaces are not allowed in variable names?

The reasons that spaces were historically disallowed in variable names is that it tends to introduce ambiguity into language grammars, where a space separating two identifiers may be meaningful (e.g. Haskell).

Can variable names have spaces in them Java?

Because a Java variable name can’t have spaces, a style called camelCase is usually used for variable names with more than one word. camelCase capitalizes the first letter of each word except the first word like firstName or numberOfDogs .

What are 2 rules for naming variables?

Rules of naming variables

  • Name your variables based on the terms of the subject area, so that the variable name clearly describes its purpose.
  • Create variable names by deleting spaces that separate the words.
  • Do not begin variable names with an underscore.
  • Do not use variable names that consist of a single character.

Which names Cannot have spaces?

    Why are there spaces in a variable name?

    The reasons that spaces were historically disallowed in variable names is that it tends to introduce ambiguity into language grammars, where a space separating two identifiers may be meaningful (e.g. Haskell).

    Are there spaces in variable names in scratch?

    In contrast, in a block-based language like Scratch, there is no such problem — variable names are typed into their own text field, so there is no parsing problem and thus Scratch allows spaces in variable names. When you use a variable in Scratch, you select the declared name from a dropdown.

    When do you need spaces in a variable name in SAS?

    To read them in SAS, we need to know how to read variables having spaces in their names. It is also required when we transpose our variables and the variable whose values name the transposed variables in the output data set contains special characters.

    How to concatenate two strings with one space between them?

    The variables can then be combined using a string CONCAT function which will combine the two variables and insert the single blank space between them. Because the new variable, NAME, is a string variable, it must first be initialized with a STRING command. STRING NAME (A51). COMPUTE NAME = CONCAT (RTRIM (FIRST,’ ‘), ‘ ‘, LAST).
