the difference between \r and \n

[YarvinG Liu]

i write two codes:
printf("123\r");
printf("123\n");
the lattar. as we all know. the output will be:
123
press any key to continue

but the formmer will be:
press any key to continue

which means data:123 has lost.
Y?

\r move the cursor back to the start of the line, the "press any key.." is
then written over the top of 123. Its probably safest to always go \r\n if
you are on windows systems.
