I am not getting that can we use clrscr(),getch(), and getlien(),gotoxy() what is the purpsoe of?

These are graphical functions. So, when you are using GUI as windows you use following functions:clrscr() - Clear the screengetch() - get a single character from input streamand gotoxy() is a very special function in windows like GUI, it is used to send a user on a particular position of a screen. When we divide screen horizontally (i.e.

Left to right or vice versa) we say it is divided in rows and when its in vertical (i.e. Top to bottom or vice versa) format it is column. To place cursor on a particular row+column gotoxy() is used.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
