back a line

[madmardigan53]

I know that (char)8 is backspace, 13 is carriage return, and 10 is line break, but what is the ASCII equivalent of going up a line?

[madmardigan53]

#include<func.h>/*contains iostream & some of my own functions*/
int main(int argc,char*argv[])
{
 cout<<"yo\n"<<'\v'<<'h';
 getch();
 return 0;
}
/* Output:
yo
(mars)h
Desired Output:
ho*/

'\v' neither went up nor down one line.
I wish to output something, then a line break, then go back to the previous line to edit it.

#include<func.h>/*already includes conio.h*/
int main(int argc,char*argv[])
{
 cout<<"laj\n";
 gotoxy(1,1);
 cout<<"f";
 getch();
 return 0;
}
/*Desired Output:
faj
Result:
[Linker error] undefined reference to `gotoxy'*/

dev-cpp
this also occurred when i attempted to change textcolor

[madmardigan53]

#include<func.h>
int main(int argc,char*argv[])
{
 cout<<"laj\n";
 gotoxy(1,1);
 cout<<"f";
 getch();
 return 0;
}
/*Output:
faj*/

also works for textcolor-thx
