Sign ' is the same as \' ?
-
Hello everyone, I am surprised to see that the value of sign ' is the same as \'. So, there is no need to add sign \ before sign '? In my past knowledge of sign ', we always need to add sign \ before sign '. Any comments? Here is my simple program to test.
int main (int argc, char** argv) { char* p1 = "Hello \'World\'"; char* p2 = "Hello 'World'"; int result = 0; result = strcmp(p1, p2); return 0; }thanks in advance, George -

'is different from\':-D (just kidding). Talking a bit seriously, you need such an escape sequence (that is symbol\') in circumstances like the following:char c = '\'';

Hi CPallini, Actually I am also confused when I tried that, "Hello 'World'" is the same as "Hello \'World\'". I have also tried your sample. Now I am more confused... 1. What is the rule when we should use \' or single ' ? 2. When there is no differences between \' and '? (like my Hello 'World' sample) regards, George

CPallini stated, you need to use\'only when the compiler can get confused. technically,\'is the same ascii code as the character'. just same as\"is the same ascii code as the character". so, in brief, ben you use'in a string (so, rounded with"s), you don't need to use the escapment char (\). when you use"as a single char, no need either to use\. some examples:"Hello \'World\'"is the same as"Hello 'World'"."Hello **"**World""is forbidden because the second"char is understood as the end of the string. here, you MUST write:"Hello **\"**World**\"**"'"'is the ascii code of the"character.'**'**'is forbidden. here again, the second'char is understood as the end of the character specification. You MUST write:'**\'**'. get it now ? subsidiary question: please, for god' sake, in what school level are you, and how old are you ? i'm not judging you, i'm questionning myself.

Hi. You use single ' inside a string delimited by " characters i.e.
char* p2 = "Hello 'World'";You use the \' when iusing it as a single character that need to be quoted within ' characters i.e.char p1 = '\'';Habetis bona deum
Good reply, thanks DoomedOne! regards, George
