I WANT TO IMPLEMENT THIS IN JAVA PLEASE I want to create a small user input system for a university student, where they put the season and year of when they started their uni course. For example the system will ask "What year did you start your degree?", the user will input "Autumn/2022" as a string. Now from a string format as shown, it should take that user input and calculate for example +2 or +3 years to the date. Also it needs to be able to change from Autumn, to another season depending on the amount of years it takes. So if the course will take 3 years, the student will finish "Summer/2025". How can I implement this?

I made the command cp code in c language. But when I copy a file, file permissions are not copied equally. So I want to copy the file authority as well. What should I do?

For this assignment, implement a simple stack calculator which can compute an infix expression. It should take in a string containing an infix expression, compute the result, and print it out. It should handle operators +, -, *, / and parenthesis.

Your program must have two main steps -- first convert the expression to postfix, and then compute the result using the algorithms discussed in class and textbook. These algorithms require that you use a stack. You must implement your own stack, you may not use a library that implements a stack. No credit will be given if you don't implement your own stack.

Although your textbook contains implementations of a stack, I encourage you to try and implement your own stack, using the textbook as a reference if you need it. You can keep your stack simple if you wish -- e.g. it doesn’t need to be templated, it can just hold a simple data type like char. Additionally, it doesn’t need to handle error conditions because we are guaranteed a string containing a syntactically correct infix expression. You may implement either an array-based stack or a link-based stack.

To keep things simple, you may make the following assumptions:

- there are no spaces or other whitespace in the string

- all the operands are single digits

- the result of every operation is a single digit. For example, 2+3 is allowed because the result is 5. 5*3 is not allowed because the result is 15, which is two digits. 5+3+4 is not allowed because even though the first operation is 8, a single digit, the result of the second operation is 12, two digits. 5+3-4 is allowed because the result of the first operation is 8, and the result of the second operation is 4

- any string entered contains a valid, syntactically correct infix expression with balanced parenthesis (if any)

Conversion between int and char

The expression contains both char and int data, because each operator is a char and each operand is a digit. The easiest way to handle this is to implement a stack which supports char data. Since we know all our operands are single digits, we can simply push the character representing the digit onto the stack. Note this character will be the ASCII value of the character, not the integer value! As an example, the character '7' is ASCII value 55, '8' is 56, etc. If you need the actual integer value of the character, in this case 7, there is a convenient way to determine it. You can subtract the ASCII value of zero, '0' from the character. For example,, the following code will store 7 in i:

char c = '7';

int i = c - '0';

To get the character back, you can add '0' to an integer.

Extra Credit

For up to 10% extra credit, modify your program to remove the assumption that the string contains a valid, syntactically correct infix expression. It should compute the value if the string is valid, and gracefully handle an invalid string.

How can i bubble sort a sentence in a char array in c++

This is the prototype of the function:

char* sort(char string[], int numOfWords, int lengthOfWord);

This is the testing code in the main file:

char words[] = "CAT FAT BAT HAT RAT";
printf("Before sort: t%s\n";words);
char result = sort(words; 5; 3);
printf("After sort : t%s\n"; result);

Expected output:

Before sort: CAT FAT BAT HAT RAT
After sort: BAT CAT FAT HAT RAT

Write a MIPS assembly program that calculates the sum of all the elements in the following array: int array[10]={12,21,3,40,15,6,17,8,29,10}

create a program in java that will evaluate a logical expression (compound proposition) based on the given truth values of individual propositional variables. The logical expression may include the logical AND or the logical OR operators. The NOT operator will be included in the variable names itself. So, a proposition such as ¬a would appear as na in the logical expression.

Here is an example of a logical expression using proper notation:

a ∧ b ∨ ¬c ∨ d

This expression will be represented as the following in this program to accommodate simple keyboard input:

a and b or nc or d

The logical operators will be evaluated left to right. Parentheses will not be included.

input the following information:

• number of variables in an expression, between 2 and 5

• the truth values of each of these variables

• a logical expression involving these variables, their negated counterparts and the logical operators and/or

List and discuss two key differences between class diagrams in analysis and those in design. What are some factors that need to be considered in determining an appropriate design pattern to utilize? Please identify at least 3-4 factors and elaborate on why these factors are important.

A marketing survey looked at the preferences of hot drink size among 1275 random
customers of a coffee shop chain. The survey was also interested in whether the customer’s gender
affects their preference. The results of the survey were used to estimate the probabilities in this joint
probability distribution:
Tall (T) Grande (G) Venti (V)
Female (F) 0.12 0.24 0.06
Male (M)    0.08 0.38    0.12

a) What is p (M, T), the joint probability that a customer in the survey was both male and prefers tall
drinks?
b) What is p (F), the marginal probability that a customer in the survey was female?
c) What is p(G), the marginal probability that a customer in the survey prefers Grande drinks?
d) What is p (V | M), the conditional probability, given a customer in the survey was male, that he prefers
venti drinks?
e) What is p (F | V), the conditional probability, given a customer in the survey prefers venti drinks, that the customer was female?
f) There are two random variables in this situation, drink size and gender. Are they independent or dependent? Explain how you arrived at the answer and show your calculations.

Develop a program Grades.java that collects the user's (students) name, course name, and the score for three quizzes. You are supposed to read this data from the keyboard using the Scanner class. Calculate the total score and the average score.

Further, using the grading scale below, based on the average score computed above, your program should calculate and output a letter grade. and the range boundaries should be configured properly (i.e.: exactly 90 and above is an A, and anything less than 90 to exactly 80 is a B). The grading scale to use is as follows:

Note: The E Category is not a typo.

Declare the variables in the order studName, courseName, scoreQuiz_1, scoreQuiz_2, and scoreQuiz_3, totalScore, averageScore, and letterCategory. Make sure you declare the variables studName, courseName, and letterEvaluation as String class variables. Select proper data type for the variables totalScore and averageScore. The data type should support decimals. Use a constant variable NUM_OF_Quizzes to compute the average score.

Things to watch for: As you are determining your logic for your if statements in this project, consider that a percentage of 90.0 results in an A, 89.8 results in a B category, 79.12 results in a C category, and 69.994949 results in a D category. That last example is a bit extreme, but the idea is to not try to predict how many 9s after the decimal you need to account for. Just think of where the last boundary ends and where the next one begins, and how you might use your mathematical operators to account for that (is it less-than-or-equal-to, or just less than?).

Formatting: Import the package DecimalFormat to format the average score data. You do this by typing: import java.text.DecimalFormat; either below or above the line: import java.util.Scanner;

Then create a DecimalFormat object by typing: DecimalFormat df = new DecimalFormat("##.00"); either above or below the line Scanner scnr = new Scanner(System.in);

A format with 2 digits would be displayed by using the df as follows:

System.out.println("The average score is: "+df.format(averageScore));

Pseudocode: Prior to writing the Java code for the project, develop a document in pseudocode that outlines how the program will flow. Remember that there are no specific rules regarding pseudocode, but rather you should write pseudocode in a way that is human-readable and understandable (English for this assignment).

The following example is what your program might look like:
