And before you dig straight into the answers provided, remember that system() calls should be avoided for reasons.

Regarding you question:

It really depends on the console that you are dealing with. You can, for instance, use escape characters to move the cursor backwards, write whitespaces to "erase" the printed characters and then move the cursor backwards again. Again, it won't work on SL. Have you checked this thread?

Answer 6

clrscr();

OR

system("cls");

Answer 7

#include<iostream>
using namespace std;
int main()
{
int i;
char ch;
for(i=0;i<10;i++)
cout<<"Hello world";
cout<<"\n\n\nEnter :\n C To clear Console.\n E To Exit.";
cin>>ch;
if (ch=='c' || ch== 'C')
system("cls");
else if(ch=='e' || ch=='E')
exit(0);
return 0;
}

-----------------------------------------
For -
● Windows - use cls
● linux - use clear
