make the middle letter blink - turbo-c++

Question

I've already solved this by not displaying the last letter of the word then locating the last letter and making it blink then I displayed the word inversely minus the last letter of course.
#include<string.h>
#include<conio.h>
#include<iostream.h>
#include<stdio.h>
char text[255];
int txtposition,txtlength;
void main()
{
clrscr();
gets(text);
txtlength=strlen(text);
char lastchar=text[txtlength-1];
cout<<"Your text is: ";
for(txtposition=0;txtposition<txtlength-1;txtposition++)
{
cout<<text[txtposition];
}
textcolor(WHITE+128);
cprintf("%c", lastchar);
for(txtposition=txtlength-2;txtposition>=0;txtposition--)
{
cout<<text[txtposition];
}
getch();
}
Thank you for all your help!

Answer 1

To make the middle character blink, either your output terminal needs to be capable to present blinking characters using a special terminal control code as described here, or use the gotoxy() function from a separate thread, that displays a ' ' or the actual character, alternating for a specific blink frequency.

Answer 2

The standard C++ library does not provide any facility for making characters blink.
You can do that in platform-specific ways, but it's worth noting that Windows console windows do not (as far as I know) directly support text blinking, like the original IBM PC's text screen mode did. On the original IBM PC one bit of the color specification could be configured to either yield high intensity or blinking, with blinking control as the default. I always reconfigured it to high intensity in my programs, and in the corresponding mechanism for Windows console windows the bits always determine color.
So, it would be complicated to do even in Windows, unless you're running in a DOSBox, which emulates the old PC. I don't know what functionality it offers. Maybe it even does blinking.
But you can easily mark the relevant letters in other ways.
For example, you could use
uppercase versus lowercase,
underlining characters placed on the next line,
parentheses (as you did in your example here),
colors (platform specific),
a different font, boldness, whatever.
I recommend updating to a modern compiler, if you have an ordinary modern PC. Compilers are free. Also you need better learning material, e.g. void main is non-standard and is only accepted by a few compilers.

Looks like for Turbo C/C++ you can you use the Graphics library and/or builtin conio functions. ( https://answers.yahoo.com/question/index?qid=20080813072809AAEguz0 )
But the above is not portable as the graphics library is specific to Turbo and conio is specific to some dos based compilers/libraries.
If you move to the a complier like gcc/g++ then you might want to look at curses library: http://tldp.org/HOWTO/NCURSES-Programming-HOWTO/
