Two string literals have the same pointer value?

Question

When I run this program using MinGW, im getting output as \"=\"

#include

using namespace std;

int main()
{
 char *str1 = \"Hello\";
 char *         


        

Answer 1

The type of a string literal like "Hello" is array of const char, therefore, you are directing two pointers to something that is not allowed to ever change.

The C++ standard gives compilers the freedom to merge identical constant values together (note that compilers are not required to do so).

Related: The declarations are therefore invalid and must be modified to:

const char *str1 = "Hello";
const char *str2 = "Hello";

or if you want

char const *str1 = "Hello";
char const *str2 = "Hello";

which reads nicely when reading right-to-left:

str1 is a pointer to const char

.
