To determine whether Name$ is a numerical constant, numerical variable, string constant, or string variable, we need to understand the characteristics and definitions of each term.
Numerical Constant:
- A numerical constant is a fixed value that does not change during the execution of a program.
- It represents a specific number or value.
- Examples of numerical constants include 1, 3.14, -5, etc.
Numerical Variable:
- A numerical variable is a storage location that can hold numerical values.
- It can be assigned different values during the execution of a program.
- Examples of numerical variables include x = 5, y = 10, etc.
String Constant:
- A string constant is a sequence of characters enclosed in quotation marks.
- It represents a fixed string value that does not change during program execution.
- Examples of string constants include "Hello", "World", etc.
String Variable:
- A string variable is a storage location that can hold a sequence of characters (string).
- It can be assigned different string values during program execution.
- Examples of string variables include name = "John", message = "Welcome", etc.
Based on the given information, Name$ is a string variable because it has the following characteristics:
- It starts with a capital letter, indicating it is a variable.
- The presence of the "$" symbol suggests it may be a string variable.
- The name itself, "Name$", implies it is storing a value related to a name or string.
Therefore, the correct answer is option D: String Variable.
