In C write a program that reads its input into an array and then uses selection sort to sort the array. In selection sort, we first find the smallest element in the array and exchange it with the first array elements value; then we find the next smallest element in the array and exchange it with the second array elements value; and so on, until the array is sorted. The program should allow the user to enter input. Also the program should use local prototypes and comment all variable and constant declarations. And the program should not use pointer
In Main it should include the following:
func.protype
var.declars
n=table_fill (a, maxsize);
table_print (a, n);
table_sort (a, n);
table_print (a, a);
return 0;
Have your program include four functions, besides main, which perform the following functions:
1. Read in an undetermined number of array elements
2. Print the array elements (call this function both before and after the elements are sorted). Use the code below
cnt = 0;
while ((r=scanf(%i, &next)) != EOF && cnt < max)
{
if (r == 0) /* invalid input data */
{
printf(Nonnumeric data entered. Please enter a number.);
while (getchar( ) != ) /* flush invalid data */
;
}
else
a[cnt++] = next;
}
if (r == 1) /* another value was read, but the array is full */
printf(Error - too many values. Array size is %i. , max);
3. Sort the array elements use the code below
Selection Sort
algorithm in pseudocode
for i = 0 to (n - 2)
min = ai
min_index = i
for j = (i + 1) to (n - 1)
if aj < min
min = aj
min_index = j
endif
endfor
swap(a, i, min_index)
endfor
4. Swap two elements of an array (this function will be called by your sort function)
Do not use any jump statements, e.g., the break statement.
Declare the maximum array size as a constant MAXSIZE with a value of 10.
Run when program when user input the following sets:
1. 5 12 -7 3 0
2. 1 2 3 4 5 7 6
MAKE SURE THAT THE PROGRAM CHECK THE THESE STATEMENT: "Some input that will trigger each of your error checks, e.g., what happens when you enter more values than your declared array size or when invalid (nonnumeric) data is entered. Flush the invalid data and continue reading until end-of-file or the array is full. Print appropriate error messages for invalid character data and for too many values. Data items should still be sorted, even if invalid character data is encountered or too many values are entered."
