C Language Programming topic (II)

To write a program implementation:
(1) Generate 300 random four-digit numbers, and then save these 4 digits to Rand.txt;
(2) The number of single digits and thousands in the statistical Rand.txt equals to 10 digits and the sum of the Hundred;
(3) The number that satisfies the condition 2 is sorted in reverse order to output it to out.txt.
