numerical methods Please write the code in c++. Provide code in text format so that I can run. Explain in detail.

Pls make a code for this on c++ and make sure it is 100% correct. i wastred 4 questoins on this  and they all are not correct.  Write the code as described in the questions below. Submit your code electronically in the box at the bottom. You may only use Java, C# or C++. The economy is defined using a 2-dimensional data structure:   A “payday” will be considered to be any region of $ values where all cells in the region are connected either vertically or horizontally. For example, the following illustrates a matrix with 5 rows and 8 columns containing three objects. $’s and P are used in the diagram to represent the two types of values: PPPP$PPPPPP$$PPPPP$$PPP$PP$PPPP$P$PPP$$$ a)   Write a program to read in the data from the text file and store it into a data structure. Your program should output it to the screen after it has read in the file. (If you can’t get this to work hard-code the above example and continue to part b). Here is a sample text file (containing the above data):…

write a c++ code, in which a fucntion is using mathematical induction. add comments in each line of code.

help me solve this in c++ please  Write a program that asks the user to enter a list of numbers from 1 to 9 in random order, creates and displays the corresponding 3 by 3 square, and determines whether the resulting square is a Lo Shu Magic Square. Notes Create the square by filling the numbers entered from left to right, top to bottom. Input validation - Do not accept numbers outside the range. Do not accept repeats. Must use two-dimensional arrays in the implementation. Functional decomposition — Program should rely on functions that are consistent with the algorithm.
