Question

write a function print array to print an array on one line as: 9 8 7 6 5 4 3 2 1 0 write and test a function called bubble sort that implements this sorting method and call it from your main function. you will need to swap elements to sort the array.

Answer 1

Function print array to print an array on one line as:

void printArray(int arr[], int n)
{
   int i;
   for (i = 0; i < n; i++)
       printf("%d ", arr[i]);
   printf("\n");
}
void bubbleSort(int arr[], int n)
{
  int i, j;
  for (i = 0; i < n-1; i++)      
      for (j = 0; j < n-i-1; j++)  
          if (arr[j] > arr[j+1])
             swap(&arr[j], &arr[j+1]);
}
void main()
{
   int arr[] = {9, 8, 7, 6, 5, 4, 3, 2, 1, 0};
   int n = sizeof(arr)/sizeof(arr[0]);
   printf("Given array is \n");
   printArray(arr, n);
   bubbleSort(arr, n);
   printf("\nSorted array is \n");

What is array?
An array is a type of data structure used in computer science that contains a set of elements (values and variables), each of which is designated by an array index or key. The simplest type of data structure is indeed a linear array, also known as a one-dimensional array. For instance, an array of ten 32-bit (4-byte) arithmetic operations, to indices 0 through 9, may be stashed as ten words at memory addresses 2000,2004,2008,..., 2036 (in hexadecimal: 0x7D0, 0x7D4, 0x7D8,..., 0x7F4) so that the element with index
