Question

My program is outputting text which sometimes contains escape sequences such as “\x1B[J” (Clear screen). Is there anyway to suppress the escape sequence such that it doesn’t perform its associated action but instead gets displayed via its text representation?

I would even be interested in doing this for \n and \r.

Answer 1

Escape the \ characters by changing each occurence to \\.

Note that these sequences work only, when you enter them in source code. Check the result of the following program:

#include <cstdio>

int main(int argc, char * argv[])
{
    char test[3] = { 0x5c, 0x6e, 0x00 }; // \n
    char * test2 = "\\n"; // \n

    printf("%s\n", test);
    printf("%s\n", test2);
    printf(test);
    printf(test2);

    return 0;
}
