Data insertion in C language

Programming , Input from keyboard 8 A non decreasing ordered sequence of numbers and put it into a one-dimensional array , Enter another number elem, And put this number elem Insert into the array , And still maintain non decreasing order , If the inserted number is larger than all the original numbers, it will be placed at the end , Than the original number of hours on the front .

Programming requirements ：
1、 The data in the series are all integers ;
2、 Non decreasing order ： That is, from small to large, or allow equal situations in the middle , such as 1 3 4 5 5 6 That is, non decreasing order ;
3、 Please use the method of array to realize ;
4、 Please output strictly according to the output effect ;（ Affect the performance evaluation ）
5、 When submitting the code of the task, it is necessary to ensure that it conforms to the industry code specification , You need to indent and wrap as necessary .（ Affect the performance evaluation ）

Running effect 1：
Please enter in non decreasing order 8 It's an integer ：
2 3 3 10 15 16 28 30
Please enter elem：3
Insert elem The result is ：
2 3 3 3 10 15 16 28 30
Please press any key to continue . . .

Running effect 2：
Please enter in non decreasing order 8 It's an integer ：
3 4 10 15 16 66 78 80
Please enter elem：81
Insert elem The result is ：
3 4 10 15 16 66 78 80 81
Please press any key to continue . . .

Running effect 3：
Please enter in non decreasing order 8 It's an integer ：
11 22 33 45 56 57 77 89
Please enter elem：3
Insert elem The result is ：
3 11 22 33 45 56 57 77 89
Please press any key to continue . . .
