Write a function called del ete_repeats that has a partially filed array of characters as a formal parameter and that deletes all repeated letters from die array. Since a partially filled array requires two arguments, die function will actually have two formal parameters: an array parameter and a formal parameter of type int that gives the number of array positions used. When a letter is deleted, the remaining letters are moved forward to fill in the gap. This will create empty positions at the end of die array so that less of the array is used. Since die formal parameter is a partially filled array, a second formal parameter of type int will tell how many array positions are filled. This second formal parameter will be a call-by-reference parameter and will be changed to show how much of the array is used after die repeated letters are deleted.

For example, consider the following code:

char a[10];

a[0] = ‘a’;

a[l] = ‘b’;

a[2] = ‘a’;

a[3] = *c’;

int size = 4;

delete_repeats(a, size);

After this code is executed, the value of a[0] is ‘a1, the value of a[l] is ‘ b \ the value of a [2] is ‘ c \ and die value of size is 3. (The value of a [3] is no longer of any concern, since the partially filled array no longer uses this indexed variable.)

You may assume that the partially filled array contains only lowercase letters. Embed your function in a suitable test program
