Homework Answers

You are given an M*N matrix and K, write a program to compute the area of the sub-matrix and print the result.

A sub-matrix is a matrix formed after deleting K rows each from the top and bottom and K columns each from left and right.

Area of a matrix is defined as the product of all elements of the matrix.

Explanation

For M = 5 and N = 4, the matrix is:

1 2 3 4

5 6 7 8

9 10 11 12

13 14 15 16

17 18 19 20

For K = 1, the sub-matrix is as follows:

6 7

10 11

14 15

Therefore, the area of the given matrix is 6*7*10*11*14*15 = 970200.

Make a file by yourself named ”Integer.txt” and add 5 integer values in it. Now, write a C++ program that reads data (5 integers) from the file and store them in integer array. Also make another integer array (int result []) of same size to store the results. The program should check for each number in array if it is prime number or not. If the number is prime, update value in result[] array from 0 to 1. Lastly, write output in another file named “Result.txt”
