C++

The C++ program below reads from the file matrix.txt integers table inserting it in the 5x5 table (matrix [5][5]). The program prints the matrix on screen, calculates the sum of the elements and prints the sum on screen making use of functions print_matrix () and count_sum(). Your task is to make up the functions in question. The values situated on the rows are separated by space. #include #include using namespace std; void print_matrix(int matrix[5][5]); int calculate_sum(int matrix[5][5]); int main(void) { int matrix[5][5]; int sum; ifstream file("matrix.txt"); if (!file){ cout << "File cannot be opened!"; } else { for (int y=0; y<5;y++){ for (int x=0;x<5;x++){ file >> matrix[y][x]; } } file.close(); cout << "Matrix:" << endl; print_matrix(matrix); sum = count_sum(matrix); cout << "Sum of elements: " << sum << endl; } }

Example output:

Matrix:

11 2 4 5 6

9 8 7 6 5

1 2 3 4 5

11 22 33 44 55

1 2 4 5 0

Sum of elements: 255
