Write a program for reading a square matrix (A) 10,10, then calculate and find the following: 1- the sum of the elements of the upper triangle of the matrix. 2 - The sum of the elements of the lower triangle. 3- The sum of the main diagonal elements of the matrix. 4- The sum of the elements of the perimeter of a matrix.
Write a program that inputs the number of row and columns from the user. It then input the elements to store in the matrices. The program calculates the sum of each row and each column and displays on the screen. If it’s a square matrices, it also calculates the sum of its diagonal elements and display it on screen.?
Write a program in which the user will create an array of numbers. Take note the user will be the one to decide the number of rows and columns, and will be the onė to input the elemets of the array. Let the program display the matrix. Then, the program must ask the user which one is to display-the minimum or the maximum element of the array.
Write a program that prints an mxn matrix whose dimensions are specified by the user. Let the matrix values be random variables. You must use it within the repetition cycle. Example format: Enter dimension of matrix mxn: 2 4 The 2x4 matrix is : 1 2 3 4 5 6 7 8
Write a program that reads student scores into an array, gets the best score, and then assigns grades based on the following scheme: • Grade is A if score is • Grade is B if score is • Grade is C if score is • Grade is D if score is • Grade is F otherwise. best - 10 best - 20; best - 30; best - 40; The program prompts the user to enter the total number of students, then prompts the user to enter all of the scores, and concludes by displaying the grades
Java Program - Functions with 2D Arrays Write a function named displayElements that takes a two-dimensional array, the size of its rows and columns, then prints every element of a two-dimensional array. Separate every row by a new line and every column by a space. In the main function, write a program that asks for integer input to be assigned on a 3 x 3 array and call the function displayElements to print the contents on the next line. Input 1. Multiple lines containing integer each line Output R1C1: 1 R1C2: 2 R1C3: 3 R2C1: 4 R2C2: 5 R2C3: 6 R3C1: 7 R3C2: 8 R3C3: 9 1 2 3 4 5 6 7 8 9
Write a program that uses a 2-D array to store the highest and lowest temperatures for each month of the year. The program should output the average high, average low, and highest and lowest temperatures of the year. Your program must consist of the following methods with their appropriate parameters: a.) getData: This method reads and stores the data in the 2-D array. b.) averageHigh: This method calculates and returns the average high temperature of the year. c.) averageLow: This method calculates and returns the average low temperature of the year. d.) indexHighTemp: This method returns the index of the highest temperature in the array. e.) indexLowTemp: This method returns the index of the lowest temperature in the array. Use the following input: High temp for each month: 30 40 45 60 70 90 89 95 79 90 70 40 Low temp for each month: 10 -10 20 30 50 75 85 79 50 80 30 20
Write a program that prints the ordinal for a random integer from 20 to 100, inclusive. Example ordinals might be 31st, 62nd, 43rd, 55th. Java code: do not use arrays
Write a program that generates a 6x6 two-dimensional matrix filled with 0s and 1s, displays the matrix, and checks to see if every row and every column has an even number of 1s.
Problem2: A square matrix can be represented by a two-dimensionalarray with N rows and N columns. You may assume a maximum size of 50 rows and 50 columns. 1. Write an algorithm MakeEmpty(n), which sets the first n rows and n columns to zero. 2. Write an algorithm Add(M1, M2, M3), which adds two matrices M1 and M2 together to produce matrix M3. 3. Write an algorithm Subtract(M1, M2, M3), which subtracts matrix M2 from matrix M1 to produce matrix M3. 4. Write an algorithm Copy(M1, M2), which copies matrix M1 into matrix M2.
