C Program 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.

#include<stdio.h>
#include<conio.h>
void main()
{
    clrscr();
    int matrix1[3][3], matrix2[3][3], i, j, matrix3[3][3];
    printf("Enter matrix 1 elements :");
    for(i=0; i<3; i++)
    {
        for(j=0; j<3; j++)
        {
            scanf("%d",&matrix1[i][j]);
        }
    }
    printf("Enter matrix 2 elements :");
    for(i=0; i<3; i++)
    {
        for(j=0; j<3; j++)
        {
            scanf("%d",&matrix2[i][j]);
        }
    }
    printf("Adding the two matrix to form the third matrix .....\n");
    for(i=0; i<3; i++)
    {
        for(j=0; j<3; j++)
        {
            matrix3[i][j]=matrix1[i][j]+matrix2[i][j];
        }
    }
    printf("The two matrix added successfully...!!");
    printf("The new matrix will be :\n");
    for(i=0; i<3; i++)
    {
        for(j=0; j<3; j++)
        {
            printf("%d ",matrix3[i][j]);
        }
        printf("\n");
    }
    getch();
}
