Using the equality operator == to compare two strings for equality in C

Question

int main (int argc, **argv)
{
       if (argv[1] == \"-hello\")
            printf(\"True\\n\");
       else
            printf(\"False\\n\");
}

Answer 1

When you're using ==, you're comparing pointers. That is, it will return true if the two operands refer to the same string in memory. Therefore, it's unsuitable for use in comparing strings lexicographically.
