1. The value of a is a random integer between 0 and 99. Because the rnd function randomly generates a single-precision number (real number) between 0--1 (excluding 0 and 1), and then multiplies it by 100 to become a real number between 0--100, and int() is a rounding function, so the possible range of real numbers between 0--100 is 0--99, including 0 and 99.
2. The program executes the insertion sorting algorithm. Judging from the part ** you provide, it should randomly generate an integer within 100, and find its position and insert it in the existing ascending sequence to generate a new sequence.
3. The result is that the elements of the array d are arranged in descending order. This can be seen from the statement i=k do while i>1 and d(i-1)>a.
4. The program is aimed at 1 number, which is a randomly generated A value.

The value of a is a random integer between 0 and 99.
The program executes a direct insertion sorting algorithm.
As a result, the elements of array d are arranged in ascending order.
This segment is inserted into an element.
