Answer:
Code:
CREATE TABLE student (
stu_code INTEGER PRIMARY KEY,
prof_code INTEGER
);
INSERT INTO student VALUES (100278,null);
INSERT INTO student VALUES (128569,2);
INSERT INTO student VALUES (512272,4);
INSERT INTO student VALUES (531235,2);
INSERT INTO student VALUES (531268,null);
INSERT INTO student VALUES (553427,1);
CREATE TABLE professor (
prof_code INTEGER PRIMARY KEY,
dept_code INTEGER
);
INSERT INTO professor VALUES (1,2);
INSERT INTO professor VALUES (2,6);
INSERT INTO professor VALUES (3,6);
INSERT INTO professor VALUES (4,4);
The SQL NATURAL JOIN is a type of EQUI JOIN and is structured in such a way that, columns with the same name of associated tables will appear once only. In our Example, Prof_code will appear only once and it will be matched in both the table;
SELECT * FROM Student natural join Professor on student.prof_code=Professor.prof_code ;
Stud_code Prof_code Dept_code
128569 2 6
512272 4 4
531235 2 6
553427 1 2
EQUI JOIN performs a JOIN against equality or matching column(s) values of the associated tables and an equal sign (=) is used as a comparison operator in the where clause to refer to equality. In our example, it will only show the result with prof_code=2 from the natural join result.
SELECT * FROM Student join Professor on student.prof_code=Professor.prof_code where student.prof_code=2;
Stud_code Prof_code Prof_code Dept_code
128569 2 2 6
531235 2 2 6
In SQL the FULL OUTER JOIN combines the results of both left and right outer joins and returns all (matched or unmatched) rows from the tables on both sides of the join clause.
SELECT * FROM professor full outer join student on professor.prof_code=student.prof_code ;
Stud_code Prof_code Prof_code Dept_code
100278
128569 2 2 6
512272 4 4 4
531235 2 2 6

Game Changer Technologies has four software teams. Each of them is developing four different examples of its new game app. Which software development methodology is used by the Game Changer teams
The software development methodology used by the Game Changer teams is called; Prototyping
We are given that;
- Game changer technologies has four software teams
- Each of the teams develops 4 different examples of the new game app.
Now, since each of them is developing four four different examples of its new game app, the method being used is called prototyping. This is because prototyping is referred to as the early approximation of the final system of a product whereby such a product is built, tested and rebuilt if required until an acceptable prototype is achieved.
When the acceptable prototype is gotten, then it will be used to develop its final game app.

for item in data:
if item[0] == 'male':
males = males + 1
if item[___
]:
malesOnPhone = malesOnPhone + 1
Choices are 1, 2, 3. Answer is for if item[___]:
Three steps can be taken to construct a list of elements using a for loop: Make an empty list appear. Iterate through an iterable or set of elements. Add each component to the list's end.
What loop for sample member of the list data?An Array List can be looped through using an Iterator. If there are additional members in the Array List, the method hasNext() returns true; otherwise, it returns false. If there is no next element, the method next() raises the No Such Element Exception and returns the next element in the Array List.
FOR LOOPS and WHILE LOOPS are two popular types of loops. A For loop runs a variable number of times. LOOP TYPE — FOR LOOP When you know how many times you want to run an algorithm before stopping, you use for loops.
Therefore, Since indexation in lists begins at 0, we must compare item[0], which is “male,” with “male” in the if statement before iterating through males in the for loop.

lets do calculations with ONLY the rightmost digits, ie., 7 + 6 = 4, so we're ignoring the carry.
Then, following must be true as well:
7+5 = 3
7+4 = 2
7+3 = 1
7+2 = 0 <= this reveals our base 9
7+1 = 8

Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in StudentInfo.tsv. Assume the number of students is at least 1 and at most 20.
The program performs the following tasks:
Read the file name of the tsv file from the user.
Open the tsv file and read the student information.
Compute the average exam score of each student.
Assign a letter grade to each student based on the average exam score in the following scale:
A: 90 = < X o
B: 80 = < x < 90
C: 70 = < X < 80
D: 60 = < x < 70
E: X < 60
• Compute the average of each exam.
• Output the last names, first names, exam scores, and letter grades of the students into a text file named report.txt. Output one student per row and separate the values with a tab character.
• Output the average of each exam, with two digits after the decimal point, at the end of report.txt. Hint: Use the setprecision manipulator to format the output.
Ex: If the input of the program is:
StudentInfo.tsv
and the contents of StudentInfo.tsv are: 70 45 59
Barrett Edan 96 97 88
Bradshaw Reagan 73 94 80
Charlton Caius 88 61 36
Mayo Tyrese 90 86 45
the file report txt should contain
Barrett Edan 70 45 59 F
Baadha Boagan 9e 157 89 A
Charlton Caius 73 94 80 B
Mayo and Tyrese 58 61 36 D
Stern and Brenda 90 36 45 C
Average midterm 83.40, midterm2 76.60, final 61.60
In this exercise we have to use the knowledge of the JAVA language to write the code, so we have to:
