Authentic WGU Certification Exam Scripting-and-Programming-Foundations Questions Answers

 The algorithm’s success depends on the correct sequence of steps. The steps should first declare the variable Diff before attempting to use it in calculations. If the declaration of Diff (step 4) is not done prior to its use (step 1), the algorithm will attempt to use an undeclared variable, which will result in an error. Therefore, switching steps 1 and 4 ensures that Diff is declared before any operations are performed on it.

References: The importance of the correct sequence of steps in algorithm design is a fundamental concept in programming and can be found in introductory texts on algorithms and programming languages. It is also a standard practice in software development to declare variables before their use to avoid runtime errors.

The expression given is ( x + y^{12} ), with ( x = 12 ) and ( y = 4 ). To evaluate this expression, we substitute the values of ( x ) and ( y ) into the expression:

( x + y^{12} = 12 + 4^{12} )

Since ( 4^{12} ) is a very large number, the significant value in this expression comes from ( 4^{12} ), and the addition of 12 does not change the order of magnitude of the result. Therefore, the value of ( x + y^{12} ) is much greater than the options provided (A. 6, B. 8, C. 14). It seems there might be a typo in the expression or the options provided. If the expression was meant to be ( x + y \times 12 ), then the answer would be:

( x + y \times 12 = 12 + 4 \times 12 = 12 + 48 = 60 )

However, since this option is not available, and based on the provided options, the closest correct answer, assuming the expression is ( x + y ), would be:

( x + y = 12 + 4 = 16 )

But since 16 is not an option, and without further context, the best match from the given options would be C. 14, even though it is not the exact answer.

A compiled language is one where the source code is translated into machine code, which is a set of instructions that the computer’s processor can execute directly. This translation is done by a program called a compiler. Once the source code is compiled into an executable file, it can be run on the target machine without the need for the original source code or the compiler. This process differs from interpreted languages, where the code is executed one statement at a time by another program called an interpreter, and there is no intermediate executable file created.

Option A describes an interpreted language, not a compiled one. Option B refers to type safety, which is a feature of some programming languages but is not specific to compiled languages. Option C describes a script or an interpreted language, which can be executed immediately by an interpreter without compilation.
