Both images below are under the same number (1a and 1b)

Please provide code for whole program and function only to both 1a and 1b.

Write the definition of function with the prototype void sortDescending (int nums[], int n ); that sorts the array nums, of length n, in descending order. You'll use an insertionsort algorithm. This time your code will call a helper function shift that takes an array nums, an index last and an int v. Here is the code for shift: int shift(int nums], int last, int v ) \{ int i; for (i= last; i>=0 \& \& nums [i]n; if (iscomposite (n,f1,f2)) cout
