Write in C++ Page 138, Problem #7.  Write a program that queries the user for the number of rows and columns of two matrices (<=10), queries the user for the values stored in each matrix, then computes a third matrix that is the sum of the first two matrices and displays all three matrices.  You must use static matrices, only filling and working with the parts of the matrix that are needed to solve the problem.

If you have a square matrix (NX N) and N is an even number like (N-8), we may divide the matrix into 4 quarters. Using C++ language write a program to swap the elements in the 1st Quarter With the elements in the 4th Quarter. In other term swap the green elements with the yellow elements. 1st Quarter 3rd Quarter 2nd Quarter 4th Quarter

Write a C++ program to create a 3*3 matrix having its elements as the random values in the range [50,99] and display the matrix in the output.

In C++ Query the user for the name of a file. Open and process that file, reporting the number of words in the file and the number of words containing each letter, and the length of that word. Assume that any word exceeding nine characters is counted as a ten character word. If the same letter appears more than once, it is counted only once. The result should be a matrix of 26 rows (one row for each letter) and ten columns (one column for each word length (1-10), and the contents of the matrix must be displayed.   As an example, assume the file contains only two words - “rotten” and “egg”. When processing “rotten”, rows for r, o, t, e and n would have the contents of column 6 incremented because “rotten” is a six letter word. When processing “egg”, rows for e and g would have the contents of column 3 incremented because “egg” is a three letter word.

Please Help. In C++. Write a program that queries the user for an odd integer n, where the permissible values for n are 3, 5, or 7.  Create a 7 x 7 static matrix and use it and the rules found in the problem to produce and display an n by n magic square.  Your solution for a 5 x 5 magic square must match the solution described in the text; other solutions are not acceptable.

QUESTION 2 Write a C++ program requesting the user to decide the size of the 2 matrices. The codes then request the user to key in the elements of these 2 matrices. The codes then calculate the multiplication of these 2 matrices and display the results. You need to make sure that the correct matrix size is being used by the user in order for the multiplication of the 2 matrices can be done.

Chapter 4 write a program in C++ language to name a row with the name (Count) to calculate the number of inhabitants of the city of N as a function of the number of years T, noting that the primary population N is 3 million people and that the city is subject to the following population growth equation: N = Z (No + (700 -) No) exp

In C++: Write a function which will find the average of all elements of the sequence: {2, 4, 6, 8, 10, 12}.  Use call by reference, and return the average as the function's return value.

Write a c++ program

Create a program using java data structures That has the user enter their pay rate; the program will require the employee to enter hours for two days ( they work two days a week); and the conversion must be done. via a recursive function (all calculation and display happen in a single function). Include an additional function to prompt the user for their numbers. Do NOT USE Stack ADT, ANY ADTs, or structures that we created in class. Employee - hoursWorked : int - payRate : double   -Employee(void) Default constructor - has NO parameters and must NOT return anything. Sets both attributes to 0. -AddHours(hoursToAdd : int) : void Adds the given hours to add to the hoursWorked attribute. -SetPayRate(newPayRate : double) : void Changes the payrate attribute to the given new pay rate. -GetHoursWorked(void) : int {hoursWorked} Gives back the hoursWorked attribute -+ GetPayRate(void) : double {payRate} Gives back the payRate attribute. -GetGrossPay(void) : double {grossPay} Computes and…
