How to design a matrix calculator in c++
Objective:
Design a matrix calculator in c++ . To make the solving problem about the simple matrix easy with the help of C++ program. Each step is explained below.
Abstract:
In this project of matrix calculator we had written a program in C++ with the help of two dimensional arrays and for loop and if statement in which when user enter a matrix of order 2by2 the program give transpose, determinant, adjoints and if possible the inverse of that matrix as an output.
Steps to code program:
This program is simple however below I have explain how it is written
• First of all we include two header files which are always ncluded in every programes means iostream.h and conio.h and after it we write void main .
• Now we start basic coding of program .Here first introduces matrix and transpose arrays and row, column, i and j for a for loop as variable datatype.
• Here we insert the determinant and adjoint variable in float and inverse variable in double data type.
• Then we ask the user to entererd the matrix elements.
• Now we declare transpose ,determinant , adjoint and inverse definition.
• Here we ask the program to display output on screen.
• Now user gets the result from the screen.

Court<<inv[0][0]<<inv[0][1]
Court<<inv[1][0]<<inv[1][1];
