[SOLVED] unknown escape sequence

Shao Lung · 04-28-2011, 11:05 PM

I am practicing my C and in one of my lines i have this

Code:

 printf("\/");

how do I get to use \ to print out?
thanks in advance

Not sure I understand the question, but here:

Code:

$ cat test.c
#include <stdio.h>

int main() {
        printf("\\   \n");
        printf("/    \n");
        printf("\\/  \n");
        return 0;
}
$ cc test.c -o printf_test
$ ./printf_test
\
/
\/
$

Since \ is the beginning of an escape sequence (i.e. "\n" for newline, "\t" for tab, etc...), you have to "escape the escape", or "\\".
