clear string from the screen.

[time to c]

i want to do this.

#include<iostream>
#include<string.h>

using namespace std;

int main()
{
      string str="i have itchy....";
      stirng str2="balls.";
      cout<<str1<<endl;
      cout<<str2;
      return 0;
}

will output on the screen...

i have itchy.... 
balls.

so i just want to erase my "balls" form the screen and put something else.

Here's the deal...

If you absolutely need to stick to platform independent ISO standard C/C++, you are out of luck.

If you are working with Windows and are willing to use Win Api functions, then you are in luck.

Which?

[time to c]

i am working in windows.
btw i would like to know every possible way to do this currently not doing any important thing.

Here's a little program I made for you. Hope it helps. There are piles of Win Api functions for doing everything imaginable with console windows...

#include <windows.h>
#include <stdio.h>

void cls(HANDLE hStdOutput)
{
 COORD coordScreen = {0,0};
 DWORD cCharsWritten;
 CONSOLE_SCREEN_BUFFER_INFO csbi;
 DWORD dwConSize;

 GetConsoleScreenBufferInfo(hStdOutput, &csbi);
 dwConSize = csbi.dwSize.X * csbi.dwSize.Y;
 FillConsoleOutputCharacter(hStdOutput,(TCHAR)' ',dwConSize,coordScreen,&cCharsWritten);
 GetConsoleScreenBufferInfo(hStdOutput,&csbi);
 FillConsoleOutputAttribute(hStdOutput,csbi.wAttributes,dwConSize, coordScreen,&cCharsWritten);
 SetConsoleCursorPosition(hStdOutput,coordScreen);
}

int main()
{
 HANDLE hStdOutput;
 COORD cd;

 hStdOutput=GetStdHandle(STD_OUTPUT_HANDLE);
 printf("I've Got Itchy....\n");
 printf("...balls!\n");
 printf("\n\npress any key to continue....\n");
 getchar();
 cd.X=0, cd.Y=1;
 SetConsoleCursorPosition(hStdOutput,cd);
 printf("....feet!\n");
 printf("\n\npress any key to continue....\n");
 getchar();
 printf("\nWill Now Clear Screen!\n");
 printf("\n\npress any key to continue....\n");
 getchar();
 cls(hStdOutput);

 return 0;
}

If you want to know about mouse stuff, let me know...

[time to c]

I think i should learn some windows API some of the piece of codes are never seen by my eyes.

well i will learn it.

and about the mouse thing is it possible to point to string and clear it?
i am creating a simple console application so if i can do point and click thing in console window that would be something new for me.

yes, you must track the mouse, and you have to know the x/y coordinates of a string you want to clear.
