C Program to Find the Sum of Each Row and Column of a 2x2 Matrix

Below is a sample C program that reads the coefficients of a 2x2 matrix from the user and calculates the sum of each row and each column.

#include <stdio.h>

int main() {
    int matrix[2][2];
    int rowSum[2] = {0, 0};
    int colSum[2] = {0, 0};
    
    // Input the coefficients of the matrix
    printf("Enter the coefficients of the 2x2 matrix:\n");
    for(int i = 0; i < 2; i++) {
        for(int j = 0; j < 2; j++) {
            scanf("%d", &matrix[i][j]);
        }
    }
    
    // Calculate the sum of each row and column
    for(int i = 0; i < 2; i++) {
        for(int j = 0; j < 2; j++) {
            rowSum[i] += matrix[i][j];
            colSum[j] += matrix[i][j];
        }
    }
    
    // Output the sums
    printf("Row sums:\n");
    for(int i = 0; i < 2; i++) {
        printf("Sum of row %d: %d\n", i + 1, rowSum[i]);
    }
    
    printf("Column sums:\n");
    for(int j = 0; j < 2; j++) {
        printf("Sum of column %d: %d\n", j + 1, colSum[j]);
    }

    return 0;
}

Explanation of the Program

1. Input: The program first prompts the user to enter the coefficients of the 2x2 matrix.
2. Calculation: Using nested loops, it calculates the sum of each row and each column by updating the respective rowSum and colSum arrays.
3. Output: Finally, it prints the sums of each row and column.

Final Note

Make sure to compile the program using a C compiler and provide the input in the specified format.
