Program 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.

Expert Solution & Answer

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”.
