Unlock the Power of Matrix Addition in C Programming

Getting Started with Matrix Operations

When working with arrays in C programming, understanding how to perform matrix operations is crucial. One such operation is adding two matrices, a fundamental concept in linear algebra.

Understanding the Program Structure

The program begins by asking the user to input the number of rows (r) and columns (c) for the matrices. This information is used to define the size of the two-dimensional arrays that will store the matrix elements.

int r, c;
printf("Enter number of rows: ");
scanf("%d", &r);
printf("Enter number of columns: ");
scanf("%d", &c);

Entering Matrix Elements

Next, the user is prompted to enter the elements of the two matrices. These elements are stored in separate two-dimensional arrays, allowing us to perform operations on them.

int matrix1[r][c], matrix2[r][c];
printf("Enter elements of matrix 1:\n");
for (int i = 0; i < r; i++) {
    for (int j = 0; j < c; j++) {
        scanf("%d", &matrix1[i][j]);
    }
}
printf("Enter elements of matrix 2:\n");
for (int i = 0; i < r; i++) {
    for (int j = 0; j < c; j++) {
        scanf("%d", &matrix2[i][j]);
    }
}

The Magic of Matrix Addition

The heart of the program lies in adding corresponding elements of the two matrices. This is achieved by iterating through each element of the matrices and performing addition. The resulting sum is stored in a new two-dimensional array, which represents the sum of the original matrices.

int result[r][c];
for (int i = 0; i < r; i++) {
    for (int j = 0; j < c; j++) {
        result[i][j] = matrix1[i][j] + matrix2[i][j];
    }
}

Displaying the Result

Finally, the program prints the resulting matrix to the screen, providing a visual representation of the matrix addition operation.

printf("Resultant Matrix:\n");
for (int i = 0; i < r; i++) {
    for (int j = 0; j < c; j++) {
        printf("%d ", result[i][j]);
    }
    printf("\n");
}
