Question about cprint

[Guti14]

Would somebody be able to tell me why the line "This program accepts.... starts all the way the right side of the screen when I use cprint?

textcolor (YELLOW);
   cprintf("\n                         Welcome to my program!\n\n  ");
   printf("This program accepts two given year. The ending year must be larger");\
   printf("than the\nstarting year. The program");
   printf(" will determine how may leap years are in the range.\n");
   printf("If there are no leap years in the range, the program will");
   printf(" determine the next \nclosest leap year after the ending year.\n\n");

Probably because you're using cprintf right before your regular printf calls. See link. Pay attention to the Limits section.

But if I use just printf, the text isn't in the colour specified.

Did you read the Limits section like the man said to?

Limits
Like all other conio output functions, cprintf distinguishes between \r and \n.

\n = newline aka line feed
\r = carriage return

But there is no rule that says cprintf will print data right-aligned just because it sees spaces....
My guess is that Guti14 is mistaking the inclusion of spaces to right alignment. cprintf basically differs from printf in place that it prints the text taking the foreground and background colours into consideration.

No its printing to the right because \n tells it to go down one line but keep the current position on that line. \r would tell it to go to the beginning of the line but stay on that line.
\n\r would tell it to go down one line and then go to the beginning of the line

OOps...

learnt that........(my original impression was that the linefeed char is only useful while printing the text to a printer......the good old dot-matrix printers etc., Never knew that \n and \r would effect the display of text also and since printf appends a \r to \n it really never occured to me..)

Thanks,

well printf doesn't append \r. Nor does any normal output function. cprintf puts the console into a different mode in which it looks at \r and \n differently. In normal output \n is newline where as in the cprintf mode its line feed.

[vsriharsha]

So, printf works in a default console mode where a \n is actually \n\r and cprintf changes the console mode where a \n is strictly \n and a \r is strictly \r.
