A lazy museum keeper actually counts the visitors in the first two days of the month in his notebook, where he keeps the number of visitors per day. In the remaining days, it gives the number of visitors per day, without counting the visitors. While making up the numbers, the values are randomly made according to the values of the previous 2 days in order to be realistic and not to attract attention. When making up numbers, he sometimes adds a number between 1-8 to the smaller one, and sometimes subtracts 1-8 from the larger one. Write the function named fill, which fills the number of visitors in a month according to the number matching algorithm of the watchman, according to the first two days, which will facilitate the work of the watchman, in accordance with the following main function and the sample output. (In the function, a pointer must meet the array and a global variable should not be used. Access to array elements should be done according to the offset notation.) With C programming and be quick please.
