The operating system controls the overall activity of the computer and furnishes services such as memory management, input/output activities, and storage management.

<h3>What is operating system?</h3>

An operating system (OS) is the programme that controls all other application programmes in a computer after being installed into the system first by a boot programme. Through a specified application programme interface, the application programmes seek services from the operating system (API).

It controls the memory, operations, software, and hardware of the computer. You can converse with the computer using this method even if you don't understand its language. A computer cannot function without an operating system.

An operating system performs three primary tasks: managing the computer's resources, including the CPU, memory, disc drives, and printers; creating a user interface; and running and supporting application software.

Hence, The operating system controls the overall activity of the computer and furnishes services such as memory management, input/output activities, and storage management.

Write the definition of a function named swapints that is passed two int reference parameters. The function returns nothing but

Alja [10]

Answer:

void swapints(int *j,int *k)//Function definition.

{

*j=*j+*k-(*k=*j); //value swapping.

}

swapints(&j,&k);//call the function.

Explanation:

The above function definition takes the address of j and k variables which is stored on the pointer variable j and k.
Then the pointer variable uses the j and k value for the above expression, and the user does not need to return the value of j and k.
But when the user prints the value of the j and k variable, then he gets the swapping value of the j and k variable.
The user needs to know that the "int j" is a normal variable, but "int *j" is a pointer variable that is used to take the address of j variable.

Answer:

A. Mark the tapes before sending them to the warehouse.

Explanation:

If they had marked the tapes as sensitive information before sending them to the warehouses, it would have been easier for the people to go and store them properly, and not having them as easily robbed, they could have put them into safes, in order to prevent that when a theft entered would steal it.
