7)Write a Python program to count the number of characters (character frequency) in a string. without using functionConsider the equation and the relation “(x, y) R (0, 2)”, where R is read as “has distance 1 of”.
For example, “(0, 3) R (0, 2)”, that is, “(0, 3) has distance 1 of (0, 2)”. This relation can also be read as “the point (x, y) is on the circle of radius 1 with center (0, 2)”. In other words: “(x, y) satisfies this equation , if and only if, (x, y) R (0, 2)”.
Does this equation determine a relation between x and y? Can the variable x can be seen as a function of y, like x=g(y)? Can the variable y be expressed as a function of x, like y= h(x)? If these are possible, then what will be the domains for these two functions? What are the graphs of these two functions?
Are there points of the coordinate axes that relate to (0, 2) by means of R?
Your Discussion should be a minimum of 250 words in length and not more than 750 words.
Consider the following table:
State a java program that use Switch structure to print one of the above statements depending on the
selected day. Write comments to explain your code.
day statement
Monday " Monday is the first day of the week !"
Tuesday " Tuesday is the second day of the week !"
Wednesday "Wednesday is the third day of the week !"
Thursday "Thursday is the fourth day of the week !"
Friday “Friday is the fourth day of the week !"
Saturday “Saturday is the fifth day of the week !"
Sunday “Sunday is the sixth day of the week !"

The commissioners will have their own back-office admin module/sub system to perform their day-to-day duties. Commisioners can Log/Register complaints on behalf of the public. Commissioners will be the main end-users of the system in their quest to combat online ponzi schemes, cybercrime, online fraud and scams. They use the system mainly to pull daily and monthly reports, search for complaints from the public and check POPI Act compliance of a specific financial service provider. The work of the commissioners is complemented by numerous researchers and admin assistants.All recorded findings should be peer reviewed and approved by other commissioners before the publication process can take place. The work of the commissioners is complemented by numerous researchers and admin assistants.
Identify four use cases that has Commissioner as an Actor and use your own words to construct a brief use case description for each use case you have identified.
Use Java to develop a payroll software to assist in paying the salary of employee/staff of a certain university named XYZ University. Assume we have three employees in the university with ranks - Programmer, Admin and Librarian, write a Java program to calculate and printout the total salary of these three employees in the institution. The program should have the following features: 1) Create a public class named: Employee that would get the firstname and lastname of each employee from the keyboard/user 2) Create three objects: prog, adm and lib, for programmer, admin and librarian respectively to access the properties in Employee class. 3) Create EmployeeSalary as parent interface to store basic_sal, housing_all and transport_all. The values for these three items are fixed for all Employee and has abstract function calculateSalary. 4) Create three sub classes namely: programmer, admin and librarian to store bonus, overtime and total salary for each employee
In this project, students are to use Java to develop a payroll software to assist in paying the salary
of employee/staff of a certain university named XYZ University. Assume we have three employees
in the university with ranks - Programmer, Admin and Librarian, write a Java program to calculate
and printout the total salary of these three employees in the institution. The program should have
the following features
All values in an array must be of the same data type.
A: True
B: False
Observe the following code:
const int SIZE = 3;
int nums[SIZE] = {1, 2, 3};
for (int i = 0; i <= SIZE; i++) {
std::cout << nums[i];
}
What is wrong with this code?
A: You cannot use constants with array definitions
B: The initialization list exceeds the size of the array
C: Should be i = 1 because you need to start with the first array element
D: Should be i < SIZE so that you don't access an array element that doesn't exist
Observe the following code:
int nums[3] = {1, 2, 3};
std::cout << nums;
What will be output to the screen?
A: 1
B: 3
C: 123
D: A memory address
Provide the toString method so that when a Quiz object is printed it gives the following Output ID: //id of quiz here Topic ://The topic of the quiz here Total Marks :// marks Obtained Marks :// marks obtained here Percentage // the percentage of marks and the % symbol Also provide a separate Main class that reads the values for the instance variables and creates an instance of the Quiz class
