[amp_mcq option1=”main()” option2=”findSquareRoot()” option3=”getSaleSubtractDiscountAddTax()” option4=”openFiles()” correct=”option3″]
The correct answer is: C. getSaleSubtractDiscountAddTax()
Procedural cohesion is a measure of how well the different parts of a function work together to achieve a single, well-defined purpose. A function with high procedural cohesion has a single, well-defined task that it performs. A function with low procedural cohesion has multiple tasks that it performs, or it performs a task in a way that is not well-defined.
The function getSaleSubtractDiscountAddTax() is most likely to have procedural cohesion because it has a single, well-defined task: to calculate the total sale price of an item after applying a discount and tax. The other functions do not have a single, well-defined task. The function main() is the entry point for a program, and it typically performs multiple tasks, such as initializing variables, reading input, and displaying output. The function findSquareRoot() calculates the square root of a number. The function openFiles() opens one or more files.
Here is a more detailed explanation of each option:
- Option A:
main()is the entry point for a program, and it typically performs multiple tasks, such as initializing variables, reading input, and displaying output. Therefore, it is not likely to have high procedural cohesion. - Option B:
findSquareRoot()calculates the square root of a number. Therefore, it is not likely to have high procedural cohesion. - Option C:
getSaleSubtractDiscountAddTax()calculates the total sale price of an item after applying a discount and tax. Therefore, it is likely to have high procedural cohesion. - Option D:
openFiles()opens one or more files. Therefore, it is not likely to have high procedural cohesion.
