// C Programming \\ GCC compiler // THEIR IS NO IMAGE in this post

I am creating a bowling score board program that utilizes a number of different programming topics. I am in need of my program to be modifed so it outputs a bowling scoreboard that lists each bowling frame so the output is more visually appealing.

Program Source code:

#include

#include

#include

//function to sort the elements of an 2D array row wise

struct array_dim{

int rows;

int cols;

};

void sort(int **arr, int n) {

//(1) sorting each row elements

int a;

for (int i = 0; i < n; ++i) {

for (int j = 0; j < n; ++j) {

for (int k = (j + 1); k < n; ++k) {

if (arr[i][j] > arr[i][k]) {

a = arr[i][j];

arr[i][j] = arr[i][k];

arr[i][k] = a;

}

}

}

}

}

//functio to read the string(line) from a file

int read_line(FILE *in, char *buffer, size_t max) {

return fgets(buffer, max, in) == buffer;

}

int row_sum(int **A, int row, int N)

{

if(N <=0)

return 0;

return row_sum(A, row, N-1) + A[row][N-1];

}

int main(int argc, char *argv[]) {

//(1)checking for the command line argument

//handling command line arguments count

if (argc != 2) {

printf("Specify the file name");

return 0;

}

//(2)handling string here

//(1)And reading the values passed from command line argument

char* file = argv[1];

printf("File names passed from command line arguments is: %s ", file);

//Here fixing the 2D array size, if you want you can changeit

//but at the same time you need add that many columns in the data.txt file

int n = 4;

// (3)Handling 2D arrays

int **array;

array = malloc(n * sizeof(int *));

//checking if the memory is allocated or not

if (array == NULL) {

printf("Out of memory ");

exit(1);

}

//allocating memory for each field in the array

for (int i = 0; i < n; i++) {

array[i] = malloc(n * sizeof(int));

if (array[i] == NULL) {

printf("Out of memory ");

exit(1);

}

}

// Open the file data.txt to read the 2D array data.

//(4)Handling the files concept here

FILE *pFile = fopen(file, "r");

if (pFile == NULL) {

//printing error if there is any issue with file

printf("Error: Unable to open the file");

exit(1);

}

//reading the matrix into 2D array

int x;

for (int i = 0; i < n; i++) {

for (int j = 0; j < n; j++) {

fscanf(pFile, " %d", &x);

array[i][j] = x;

}

}

//printing the 2D array

struct array_dim temp = {.rows = n, .cols = n};

printf("Array dimensions are, No of rows are %d, No of columns are %d ",temp.rows,temp.cols);

printf(" 2D Array read from file is: ");

for (int i = 0; i < n; i++) {

for (int j = 0; j < n; j++) {

printf("%d ", array[i][j]);

}

printf(" ");

}

printf(" ");

printf("Finding the sum of 3rd row using recursion ");

printf(" ");

int sum = row_sum(array, 2, 4);

printf("Sum is %d ", sum);

//(5)passing the 2D array as Pass by Reference

sort(array, n);

//printing the results

printf(" 2D Array after sorting each row in ascending order is: ");

for (int i = 0; i < n; i++) {

for (int j = 0; j < n; j++) {

printf("%d ", array[i][j]);

}

printf(" ");

}

for (int i = 0; i < n; i++) {

free(array[i]);

}

free(array);

array = NULL;
