How To Clear My Screen

P: 1
Clear screen 'clrscr() is not a standard function, niether in C or C++. So, using clrscr() is not always give you an answer, and it depends upon the compiler you installed and what library is available too. Some says: include library as: #include <conio.h> , this is also does not help much, and most of the times, it does not work because this library : <conio.h> is not standard library too.
So, to use clear screen, you have to use :
  1. #include <iostream> WHICH IS KNOWN IN C++ and system('cls'); as in the following example:
  2. #include <stdio.h>
  3. // #include <conio.h> some compilers
  4. //ask for this library, but in our case, no need.
  5. #include <iostream> // available in C++ standard Library
  6. int main()
  7. {
  8. char x;
  9. for(int j=0; j<=10;j++)
  10. {
  11. printf('Press any key to clear the screen.n');
  12. scanf('%c',&x);
  13. // >>>>>>>>>>>>>>>>> clrscr(); you can not use it in
  14. // some compilers.......>>>>>>>>>><<<<<<
  15. // instead use this one: system('cls');
  16. system('cls');
  17. //clearscrean then leave 3 linsbefore writing vnew things
  18. for(int k=0;k<=3;k++)
  19. printf('n');
  20. for(int i=0; i<=3;i++)
  21. { // repeat each of the following
  22. // line 4 times
  23. for(int m=65;m<=80 ;m++)
  24. //m=65 is equivalant to character 'A' and so on.....
  25. printf('%c',m); // print m as characters and
  26. // not as decimal
  27. printf('----Look at value of j after each clearscreen YAHIA111%d',j);
  28. printf('n');
  29. }
  30. scanf('%c',&x);
  31. }
  32. return 0;
  33. }
