1. HW8(60pts)
The homework Due on May 19, 23:59:59 請注意：本次作業開始，請將所有的檔案從gitlab刪除，只留下當 次的作業。例如本次作業應該只需要以下檔案上傳至Gitlab

2. Part 1.(20pts)Create algorithm.h
Please create a new header named algorithm.h
Inside the algorithm, please implement two function: for_each, all_of
for_each is to show all the components in vector
all_of is to calculate all the components with int value

3. The picture below is pointer to function, please reference the latest code professor write in class.
↑This is the code professor write in class

4. Part 2.(20pts)Design UI
In main.cpp, you need to design an UI that user can choose which function to execute.
The control flow will look like below.
1. main UI
2.choose 1 and input an integer into vector.

5. 3.(assume that the vector is [10 20 30]) choose 2 to show the vector
4.choose 3 and give an operator to calculate with value 2, then choose 2 to show the result.

6. 5. choose 4 to clean up the vector, then choose 2 to check the result.
6.choose 5 to exit the program.

7. Part3.(10pts) Unit Test
We wrote 5 UT to test your algorithm.h
The test data will not be announced. You have to make all of them pass. You know this by checking Reports on Jenkins.

8. Part4.(10pts) Acceptance Test
We wrote 6 AT to test your UI

9. Addition You can use the string here
When choose 2, the output will like this “ ”
