This is an incomplete question. The complete question is given below:
Mike has never used slide presentation software before but he needs to create a presentation by the end of the week what resource would be most helpful to mike
a. The 350-page printed manual from the slide presentation software publisher
b. A free tutorial the slide presentation software publisher has posted on the company website
c. A trouble-shooting website created by a third party
d. The 350-page online manual from the slide presentation software publisher
Answer:
b - A free tutorial the slide presentation software publisher has posted on the company website
Explanation:
As Mike has a short time and no prior experience with a slide software, then in this scenario, the best, simplest and fastest way to learn and create a presentation a free tutorial which the slide presentation software publisher has posted on the company website as this is the same company that has created this particular software so he can be rest-assured that the resource he is relying on is authentic and up-to-date with information on latest features.
Moreover, it's efficient and quick way to learn from a free tutorial rather than from 350-page printed or online manual especially for a beginner.
Besides, his purpose is to create the presentation using the software and not trouble-shooting so trouble-shooting website created by a third party is not useful for him and it also might not be authentic or updated as well.
Answer:
Option B is the correct answer for the above question.
Explanation:
The control structure is a decision type structure which can be either true or false. It has two options-- If this then, does this otherwise do this. When the user wants to write he control structure then he can do this by the help of the following syntax in python language--
if(condition):
do this
else:
do this
The above question wants to ask about the concept which is used in the programming for a decision then the answer is control structure which is referred from the option B. Hence B is the correct option while the other is not because--
- Option A states about the flowchart which is the picture form of the instruction.
- Option C states about the pseudocode which is the language form of the instruction.
- The operator is also not the correct option because it is used to perform the operation.
