Chapter 2: Problem 15

Which of the following are not valid assignment statements? (Circle all that apply.) A) total = 9; B) 72 = amount; C) profit = 129 D) letter = 'W';

Short Answer

Expert verified
Answer: Options B and C could be considered not valid assignment statements depending on the programming language being used. If the semicolon is required (such as in C++ or Java), then option C is also not a valid assignment statement.

Step by step solution

01

Analyzing Option A

Option A is "total = 9;". In this statement, the variable 'total' is on the left side of the assignment operator "=", and the value 9 is on the right side. This is a valid assignment statement.
02

Analyzing Option B

Option B is "72 = amount;". In this statement, the value 72 is on the left side of the assignment operator "=", and the variable 'amount' is on the right side. This is not a valid assignment statement, as the variable should be on the left side.
03

Analyzing Option C

Option C is "profit = 129". In this statement, the variable 'profit' is on the left side of the assignment operator "=", and the value 129 is on the right side. However, there's no semicolon at the end of the statement. Depending on the programming language being used, this may or may not be an invalid assignment statement. In languages like Python, this would be valid, but in languages like C++ or Java, this would be invalid.
04

Analyzing Option D

Option D is "letter = 'W';". In this statement, the variable 'letter' is on the left side of the assignment operator "=", and the value 'W' (a character) is on the right side. This is a valid assignment statement. To conclude, options B and C could be considered not valid assignment statements depending on the programming language being used. If the semicolon is required (such as in C++ or Java), then option C is also not a valid assignment statement.
