Answer: For loop
Explanation:
Using the for loop we can get the exact number of values/outcomes we require.
For example: printf(enter 20 numbers");
for(int i=0; i<20;i++)
{
scanf("%d", &number);
}
So, this is an implementation of for loop in C. Using it we can enter exact 20 numbers not less or more than that.
Therefore, for loop is the answer.
#1) An important task that the operating system performs is ____, which keeps track of the files stored on a computer so that they can be retrieved when needed.
Answer: File Management System. Keeps track of where files are stored and determines how the files are stored following the operating system file allocation policies. It uses available storage space efficiently for files and creates a record/log of all file usage. It allocates a file to a user if is free, and if they are permitted access to it. Then de-allocates file when the user is finished with it.
Four of the basic I/O interface standard are PCI, SCSI, USB and ISA.
<h3>Standard I/O Interface</h3>
Input-Output Interface is used as an method which helps in transferring of information between the internal storage devices. A number of standards have been developed for I/O Interface.
There widely used bus standards are:
- PCI (Peripheral Component Interconnect)
- SCSI (Small Computer System Interface), and
- USB (Universal Serial Bus).
- ISA (Industry Standard Architecture)

Answer: Public
Explanation:
A top level class can have a public, as top level cannot be private and protected because the modifier private is not allowed. As, top level is a class which is not a nested class.
