Comparing two like strings returns not equal

[sravanyadav51]

Why are output:s1 and s2 not equal?

main()
{
char *s1="Hello";
char *s2="Hello";
if(s1==s2)
  printf("s1 and s2 are equal");
else
  printf("s1 and s2 are not equal");
}

You're comparing pointer values, not their contents. Try printing the hex value of s1 and s2 and you'll see they have different addresses.

To compare the value of the strings you have to use strcmp or something similar (or use C++ std::string)

you should try the strcmp() function to compare strings and by that you can exactly compare strings in string.h header file.
