Sure, here is a step-by-step solution to find the sum of each row and column of a 2x2 matrix in C: 1. Start by including the necessary header files: ```c #include ``` 2. Define a constant for the size of the matrix: ```c #define SIZE 2 ``` 3. Declare a function to calculate the sum of each row and column: ```c void calculateSum(int matrix[SIZE][SIZE]) { int rowSum[SIZE] = {0}; int colSum[SIZE] = {0}; // Calculate the sum of each row and column for (int i = 0; i

Question

Sure, here is a step-by-step solution to find the sum of each row and column of a 2x2 matrix in C:

1. Start by including the necessary header files:
```c
#include <stdio.h>
```

2. Define a constant for the size of the matrix:
```c
#define SIZE 2
```

3. Declare a function to calculate the sum of each row and column:
```c
void calculateSum(int matrix[SIZE][SIZE]) {
    int rowSum[SIZE] = {0};
    int colSum[SIZE] = {0};

// Calculate the sum of each row and column
    for (int i = 0; i < SIZE; i++) {
        for (int j = 0; j < SIZE; j++) {
            rowSum[i] += matrix[i][j];
            colSum[j] += matrix[i][j];
        }
    }

// Print the sum of each row
    printf("Sum of each row: ");
    for (int i = 0; i < SIZE; i++) {
        printf("%d ", rowSum[i]);
    }

// Print the sum of each column
    printf("
Sum of each column: ");
    for (int j = 0; j < SIZE; j++) {
        printf("%d ", colSum[j]);
    }
}
```

4. In the main function, declare a 2x2 matrix and prompt the user to enter the coefficients:
```c
int main() {
    int matrix[SIZE][SIZE];

printf("Enter the coefficients of the matrix:
");
    for (int i = 0; i < SIZE; i++) {
        for (int j = 0; j < SIZE; j++) {
            scanf("%d", &matrix[i][j]);
        }
    }

// Call the calculateSum function
    calculateSum(matrix);

return 0;
}
```

5. Compile and run the program. Enter the coefficients of the matrix when prompted, and the program will calculate and display the sum of each row and column.

Note: This solution assumes that the user will enter valid integer coefficients for the matrix. You may want to add error handling code to handle invalid input.

I hope this helps! Let me know if you have any further questions.
