Chapter 2: Problem 13

Is the variable name sales the same as sales? Why or why not?

Short Answer

Expert verified
Answer: In case-sensitive programming languages, the variable names "sales" and "Sales" are considered different due to the difference in casing for the first letter.

Step by step solution

01

Understand Case Sensitivity in Variable Names

In programming languages like Python, Java, and C++, the variable names are case-sensitive. This means that names with different cases are treated as separate variables.
02

Compare "sales" and "Sales"

In the case of "sales" and "Sales", the first letter of the variables is different ("s" vs. "S"). Since we are working with a case-sensitive language, they are considered to be different variables.
03

Conclusion

In a case-sensitive programming language, the variable name "sales" is not the same as "Sales." The difference in casing for the first letter makes them separate variables within the code.
