Difference between \r and \n?

[duckwithanokhat]

In C code I know that \n makes a new line, but what does \r do? Pls explain in easy to understand english, wikipedia cannot do that for me.

Look up carriage returns, they kind of do the same thing, but it also depends on the environment.

 

\r\n is a new line in windows for example. 

\n is a new line in unix

So from what I looked up do carriage returns move your cursor to the beginning of the line you put the code in?

In C (and not only C):

\n - new line

\r - carriage return

In Linux you only need \n, while in window you need \n\r to perform the same task: a new line with the cursor on the first column.

That is how the different operating systems were coded.

 

In C you would usually use these when you want to make a new line in a printed text (either in an output console or on some display box).

It all comes from typewriters that had two separate functions, one for returning the head to the left of the paper and one for advancing the paper a line. UNIX decided to do away with compatibility, dos and then windows didn't. Now it's just one of those annoying backward compatiblity things you have to deal with but both platforms mostly consume the other and ignore the differences except occasionally.

/n simply starts a new line on a output./r can be used in a system.in in Java so when you click the console it automatically takes you to the next line to enter each value , for example.

public static int[] getIntegers(int number) {
    System.out.println("enter " + number + " numbers \r");
    int [] values = new int [number];

    for (int i=0; i<values.length; i++){
        values [i]= scanner.nextInt();
