Answer:
Explanation:
The following is written in Java. It creates the function num_eights and uses recursion to check how many times the digit 8 appears in the number passed as an argument. A test case has been created in the main method and the output can be seen in the image below highlighted in red.
   public static int num_eights(int pos){
        if (pos == 0)
            return 0;
        if (pos % 10 == 8)
            return 1 + num_eights(pos / 10);
        else
            return num_eights(pos / 10);
    }

Most of the database users perform the data searches by using the forms. A form can be used to enter, edit and display the data from the data source. Its a user interface in fact that fetches the data from the database. Reports have used the display the data for a certain type of user, and the viewing table does not look feasible to search from a very large database, and the databases are usually large. No calculation is required for searching the data, and we only need to write queries in the right syntax.

Answer and explanation :
the three control problems associated with competing process are
- MUTUAL EXCLUSION : We know that some resources are shareable and some are not shareable. which means only one process can access the resource at a time this type of resources are called critical resources this code can be access at only one process at a time. the other process if required to access should not be allowed 
- DEADLOCK: this hold the process without complete for example suppose there are two resources R1 and R2 and two process P1 and P2 and P1 use R1 and P2 use R2 but after some time when P1 needs R2 but R2 is not available as it is used by P2 so the all process will be on hold
- STARVATION : when priorities are given to the process as high priorities and low priorities. And high priorities process always competing  then low priorities process have to wait for very long time this is called starvation
