/prog/ - Simple C Programming question.

Name: Anonymous 2013-06-21 14:45

OK, let's say I have a simple program that uses the printf function to print out "0 1 2 3" from some sort of increment loop.

When the program finishes printing the numbers, they come out as:

0
1
2
3
-----

Ok. Here's my question: How can I make it so that as the program prints out each number, each previous number is replaced by the newer one. So when the program ends, the only think you'll see on the screen is a "3", instead of "0 1 2 3".

This isn't to say that the previous numbers in front of three weren't displayed. It's just that they were displayed and replaced with the next number so quickly that it's hard for the human eye to see them go by.

printf("\x1B[A"); moves the cursor up; try doing that after printing a newline.

instead of \n, use \r

This will clear out the entire terminal, OP is asking for a method of clearing only the previous line.

Yeah do what >>8 says, just remove the EOL char.
I don't see why you would want to do that tho

Make sure you #include <conio.h> and use the clscr() function

gotoxy(x,y) where x and y are the coordinates in your terminal.

Name: Anonymous 2013-06-21 20:47

GoToCoordinatesInConsole(x, y, GetConsoleDeviceContext(NULL), NULL, NULL, NULL);

Aren't particular sets of escape sequences tied to a particular type of architecture/terminal, i.e. "implementation-dependent"?

>>11
It would be hard to assume the use of this library nowadays (unless you use something like Borland Turbo C 2.01 on a regular basis).

The \r escape sequence is defined in the standard.

\r is obviously part of the standard. Notice I was referring to >>7 . \x1B[A is an ANSI escape sequence and its interpretation is not guaranteed (needs ansi.sys driver on DOS, or some derivative like NNANSI.COM). Unless that was a troll as well.

int main(int ac, char ** as){

     int i = atoi(as[0]);

     if(i > 10){

          printf("Please enter a number less than 10");

          return -1;

     }



     for(int x = 0; i > x; x++){

          printf("%d\b",x);

     }

     printf("%d",i);

     return 0;

}

Argument 0 contains the executable name. I suppose you meant int i = atoi(as[1]);.

Yes. I wrote it in the reply field and never actually bothered to test it, sorry.

^H == \b == 0x08

While K&R, and also (probably as a result of the former) the Linux Coding Style doc do promote the use of such bracketing, it is made clear that function definitions are an exception, and should definitely look like this:



type function()

{

        stuff

}

So you prefer to use

if (condition) {

    blah blah

}

over the superior

if (condition)

{

    blah blah

}

Not >>27-tono, but yeah, I prefer more non-fluff lines of code to be displayed at once.
