Programming Code to Add Two Matrices

Programming Code to Add Two Matrices

To add two matrices in C++ Programming, you have to ask to the user to enter the elements of both the matrix, now start adding the two matrix to form a new matrix. After adding two matrices display the third matrix which is the result of the addition of the two matrices as shown in the following program.

Following C++ program add two 3*3 matrices to form the third matrix :

/* C++ Program - Add Two Matrices */
		
#include<iostream.h>
#include<conio.h>
void main()
{
	clrscr();
	int mat1[3][3], mat2[3][3], x, j, mat3[3][3];
	cout<<"Enter matrix 1 elements :";
	for(x=0; x<3; x++)
	{
		for(j=0; j<3; j++)
		{
			cin>>mat1[x][j];
		}
	}
	cout<<"Enter matrix 2 elements :";
	for(x=0; x<3; x++)
	{
		for(j=0; j<3; j++)
		{
			cin>>mat2[x][j];
		}
	}
	cout<<"Adding the two matrix to form the third matrix .....\n";
	for(x=0; x<3; x++)
	{
		for(j=0; j<3; j++)
		{
			mat3[x][j]=mat1[x][j]+mat2[x][j];
		}
	}
	cout<<"The two matrix added successfully...!!";
	cout<<"The new matrix will be :\n";
	for(x=0; x<3; x++)
	{
		for(j=0; j<3; j++)
		{
			cout<<mat3[x][j]<<" ";
		}
		cout<<"\n";
	}
	getch();
}

C Program Reverse a String Use Recursion - Program reverse the string 'Using Recursion'. C program uses recursive function & reverses the string in the same 'Memory Location'. Eg 'Superman8' will be reversed to '8namrepuS'

The C Programming Pointers & 2D Arrays - As we know that the one "Dimensional Array" name works as a pointer to the base element of the Array. However in the case "2D Arrays" the logic is slightly different. You can consider

C Perform Matrix Multiplication Recursion - C program, 'using recursion', performs Matrix multiplication of 2 'matrices' and displays the result. We use 2 D array to represent a matrix & resulting matrix is stored in different matrix

Code Converts Binary Number to Decimal - C language code to convert binary to decimal number system. The Binary number system is base 2 number system & uses only 2 symbols to represent all its numbers i.e. 0 and 1. Input

What is The Function Overloading in C++ - Code sample about C++ language Function overloading. If a "C++ Class" have multiple member functions, having the same name but different parameters and programmers

C Binary Equivalent of input Hexadecimal - Program to display Binary equivalent of an input Hexadecimal Number (Hex to Binary Converter). Number will be accepted if you press Ctrl-Z & then ENTER after inputting...

Code Checks a String is Palindrome or Not - C Program to check Whether a given string is palindrome or not 'using recursion'. Program, with recursion, determines the entered string is a 'palindrome' or not. Palindrome is a word,

Implementations for AA-Tree in The C++ - Internal method to insert into a subtree. x is the item to insert. t is the node that roots the tree. Set the "New Root". Internal method to remove from subtree. x: the item to remove.
