String constants (literals) are saved into the .data section of the program,
Here is the sample program to show that. if() is essentially comparing the
addresses of two pointers which is same.
int main()
{
char *p="persons";
char *q="persons";
char *r="persons";
char *s="persons";
printf("%x %x %x %x\n",p,q,r,s);
if(p=="persons")
printf("technical %s",p);
else
printf("true %s",p);
return 0;
}
-------------
Output:
403021 403021 403021 403021
technical persons
