Chapter 1, Problem 1R
Expert Solution & Answer
Check MarkProgram Plan Intro
The variables:
- The variable is a named location in a memory. In this location the program can manipulate the data.
- This location holds the value of the variable.
- The value of the variable gets changed in the program.
- The C++ variable can be any type like “int”, “float”, “char” and so on.
Explanation of Solution
Rules for naming the C++ variable:
- The name of the variable must begin with a letter or underscore.
- The name of the variables is case sensitive.
- The name of the variable can be constructed with digits and letters.
- Special symbols other than underscore are not allowed in the variable name.
- Valid variable names are, “i_think_i_am_valid”, “i_may_have_2_many_digits_2_be_valid”, “_I_start_and_end_with_underscores_”, “I_AM_LONG_AND_HAVE_NO_LOWER_CASE LETTERS”
- Example for invalid variable name is “I_Have_A_Dollar_$ign”. This is invalid because the name contains the special character “$”.
From the given set of variable names, the invalid variable name is “I_Have_A_Dollar_$ign”. Hence the correct option is “d”.
