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.

Code:

#include <string.h>

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

In this case there is no need since it is in a string literal, and thus the delimiters are double quotes. However, if you want to specify it as a char literal, you need to escape it:

Code:

char c = '\'';
