Now one by one test:

Escape character \a |-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|- |-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-

<span style= "color: #33cc00;" > #include <stdio.h> #include <stdlib.h>int main () {    printf ("\a");    return 0;} </span>

Run, you can hear a beep. Personally, this escaped character is the most attractive.

Or you can look like this:

<span style= "color: #33cc00;" > #include <stdio.h> #include <stdlib.h>int main () {    char beep = 7;    printf ("%c", beep);    return 0;} </span>

Or something like this:

<span style= "color: #33cc00;" > #include <stdio.h> #include <stdlib.h>int main () {    char beep = ' \a ';    printf ("%c", beep);    return 0;} </span>

Or something like this:

<span style= "color: #33cc00;" > #include <stdio.h> #include <stdlib.h>int main () {    char beep = ' \007 ';    printf ("%c", beep);    return 0;} </span>

Even this way:

<span style= "color: #33cc00;" > #include <stdio.h> #include <stdlib.h>int main () {    char beep = ' \07 ';    printf ("%c", beep);    return 0;} </span>

this way:

<span style= "color: #33cc00;" > #include <stdio.h> #include <stdlib.h>int main () {    char beep = ' \7 ';    printf ("%c", beep);    return 0;} </span>

() so many! Yes,C language is unpredictable.

The above applet effect is the same.

Escape character \b |-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|- |-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-

Escape Character \f |-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-| -|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-

#include <stdio.h> #include <stdlib.h>int main () {    char anotherpage = 0xa;/* 0xa = 012, ' \f ' */    int Pa Genum = ten;    printf ("-|-|-|-");    printf ("%c-", anotherpage);    return 0;}

The result of the operation is this:

-|-|-|-
-

How does it work like a newline?

If you choose to directly output this page break phenomenon more wonderful:

#include <stdio.h> #include <stdlib.h>int main () {    printf ("\f");    return 0;}

The phenomenon is so wonderful that it makes people feel the mind. Try one more ~

Escape character \ r |-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|- |-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-

#include <stdio.h> #include <stdlib.h>int main () {    printf ("  + B = C\ra");/* There is a space betwee n symbol "and symbol +, when printf receive \ r, A go to the first space!" */    return 0;}

this feels good ~

Escape character \v |-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-

#include <stdio.h> #include <stdlib.h>int main () {    printf ("\v");    return 0;}

Originally they are a pair of son!!! <\f & \v > ...

escape character \ \ \ \ " |-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-| -|-|-|-|-|-|-|-|-|-

I think this is very not pure.

Escape character |-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|- |-|-|-|-|-|-|-|-|-|-|-

<span style= "color: #3366ff;" > #include <stdio.h> #include <stdlib.h>int main () {    printf ("A");    printf ("n");    printf ("B");    return 0;} </span>
