Answer:
The answer to this question is given below in this explanation section.
Explanation:
"difference between cd-r, cd-rw and cd-rom"
CDs are also known as WORM discs,for "write once Read many".A re writable version based on excitable crystals and known as CD-RW was introduced in the mid 1990s because both CD-R and CD-RW recorders originally required a computer to operate they had limited acceptance of use as computer software.
A compact Disc Read only memory (CD-ROM) is a read only disc.A compact disc Re-writable (CD-RW) is an erasable disc that can be reused.The data on a CD-RW disc can be erased and recorded over numerous times.CD-RW may not be readable outside of the drive it was created in.
cd-r :
CD-R is a digital optical disc storage format.A CD-R disc is compact disc that can be written once and read arbitrarily many times.
CD-R stand for" compact disc" Record-able .CD-R disc are blank CDs that can record data written by a CD burner.The word "record-able" is used because CD-R are often used to record audio,Which can be play back by most CD players.
cd-rw:
CD-RW compact disc re-writable is a digital optical disc,storage format introduced in 1997.A CD-RW compact disc can be written read erased and re-written.
in this case of CD-RW the writing laser makes permanent marks in a layers of dye polymer in the disc.CD rewrite-able discs in a similar fashion,except that the change to the recording surface is revers able.
cd-rom:
CD-Rom observation of compact disc read only memory type of computer memory in the form of compact disc that is read by optical means.A CD-ROM drive uses a low power laser been encoded in the form of tiny pits on a optical disk.The "ROM" part of the term means the data on the disc "read only memory" or cannot be altered or erased.
Answer:
True.

Answer:
Option D is the correct choice answer for the above question.
Explanation:
"exit()" is a function that is used to transfer the control of the program to the end of the program and the program gets terminated. This function defines in many programming languages. The syntax of this function is as follows--
exit() // syntax of the exit function.
Hence anybody can say that "exit" function is used to terminate the program if there are many lines belongs after the "exit()" function. Hence option D is the correct answer while other is not because--
- Option A states about the "terminate()" function which is not the function of any programming language.
- Option B states about the "return()" function which is also not the function of any programming language but "return" is a statement used to return the value.
- Option C states about the "continue()" function which is used in a loop to escape the other line of the loop and continue it.
