C++ - Matrix Addition and Subtraction with out using classes
I have given the program for matrix addition and subtraction in one function. This is a simple version.
To access the more flexible and enhanced version using the class CMatrix is using operator overloading +, -, =, ==, >> and << along with copy constructor, click here.
Source Code
#include <stdio.h>
#include <iostream>
#include <tchar.h>
#include <math.h>
int main()
{
int row1, col1;
double matrixA[24][24];
double matrixB[24][24];
double matrixC[24][24];
// Init Array
for(int i = 0; i < 24; i++)
{
for(int j = 0; j < 24; j++)
{
matrixA[i][j] = 0;
matrixB[i][j] = 0;
matrixC[i][j] = 0;
}
}
// Input the rows and cols of the matrix A and B
std::cout << "Enter rows and columns of the Matrix A and B: ";
std::cin >> row1;
std::cin >> col1;
// Input for Matrix A
{
for(int i = 0; i < row1; i++)
{
for(int j = 0; j < col1; j++)
{
std::cout << "Input For Matrix A Row: " << i + 1 << " Col: " << j + 1 << " = ";
std::cin >> matrixA[i][j];
}
std::cout << "\n";
}
std::cout << "\n";
}
// Input for Matrix B
{
for(int i = 0; i < row1; i++)
{
for(int j = 0; j < col1; j++)
{
std::cout << "Input For Matrix B Row: " << i + 1 << " Col: " << j + 1 << " = ";
std::cin >> matrixB[i][j];
}
std::cout << "\n";
}
std::cout << "\n";
}
// Matrix C = A + B
{
for(int i = 0; i < row1; i++)
for(int j = 0; j < col1; j++)
matrixC[i][j] += matrixA[i][j] + matrixB[i][j];
}
// Display Matrix C = A + B
{
std::cout << "\n\nMatrix C = A + B : " << " Rows: " << row1 << " Cols: " << col1 << "\n\n";
for(int i = 0; i < row1; i++)
{
std::cout << " | ";
for(int j = 0; j < col1; j++)
std::cout << matrixC[i][j] << " ";
std::cout << "|\n";
}
std::cout << "\n\n";
}
return 0;
}
Output
Enter rows and columns of the Matrix A and B: 3
