Answer #1

Answer:-

SUBROUTINE:- In computer programming, a subroutine is a sequence of program instructions that performs a specific task, packaged as a unit. This unit can then be used in programs wherever that particular task should be performed.

During the execution of the program, if a loop or subroutine is entered then the only one copy of this Instruction is stored in the main memory which makes it easy to call directly from main memory and access time decreases. When a Subroutine is required it can be called many times during the Execution of a particular program. A call Subroutine Instruction calls the Subroutine.

    Consider a cache of 8 lines of 16 bytes each. Main memory is divided into blocks of 16 bytes each. That is, block 0 has bytes with addresses 0 through 15, and so on. Now consider a program that accesses memory in the following sequence of addresses: Loop three times: 10 through 20; 32 through 52. Once: 20 through 35. Suppose the cache is organized as direct mapped. Memory blocks 0, 8, 16 and so on are assigned to line...

    build a phone number from digits entered by your user. Your program will loop until 10 valid digits have been entered. It will then use those digits to display the phone number entered using the format: XXXXXXXXXX (or (XXX) XXX – XXXX for extra credit). The program will ask for a digit, it will check to see if the digit is actually between 0 and 9 inclusively. If so, the digit will be stored as the next number in the...
