We'll guide you through every step, helping you grasp the essentials of coding while creating a practical program that performs matrix addition for two 2x2 matrices. Whether you're new to programming or looking to expand your skills, this guide is your key to understanding matrix manipulation. So let's jump in and uncover the magic of C programming as we unlock the secrets of matrix addition together!

Discover how to write a C program that performs matrix addition for two 2x2 matrices using this informative guide.

            
#include <stdio.h>

int main() {
    int matrix1[2][2], matrix2[2][2], sum[2][2];

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

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

    printf("Sum of matrices:\n");
    for (int i = 0; i < 2; i++) {
        for (int j = 0; j < 2; j++) {
            sum[i][j] = matrix1[i][j] + matrix2[i][j];
            printf("%d ", sum[i][j]);
        }
        printf("\n");
    }

    return 0;
}
            
        

Test the Program

Enter elements of first matrix (4 values, separated by spaces):

Enter elements of second matrix (4 values, separated by spaces):

Explanation

1. Step 1: The program starts by including the standard input/output library stdio.h.
2. Step 2: In the main() function, integer arrays matrix1, matrix2, and sum are declared to store the matrices and their sum.
3. Step 3: A nested for loop is used to input elements of both matrices.
4. Step 4: Another nested for loop is used to calculate the sum of corresponding elements and store it in the sum array.
5. Step 5: The program displays the sum matrix using printf().
