For the life of me, I can't compare the first character of this array

Question

All I want to do is pass in a char* buffer and compare that to a literal string "@" -- why is this so difficult for me.

    char* buffer = "@3702";
    string b(buffer);
    string c("@");

    if (strncmp(b.c_str(), c.c_str(), 1) == 0)
    {
        perror("Buffer malformated!");
        return false;
    }

What do I not understand about this?

Edit: haaaa, != not == whoops :)

If you just want to compare char*and use strncmp(), you don't need to use stl string for this.

int main()
{
    char* buffer = "@3702";
    char* c = "@";

    if (strncmp(buffer, c, strlen(c)) == 0)
    {
        //same string
        return true;
    }
    else
    {
        //not same string
        return false;
    }

    getchar();
}

And, remember char[] can convert to char*, so in this case, above code is similar to below code.

int main()
{
    char buffer[] = "@3702";
    char c[] = "@";

    if(buffer[0] == c[0])
    {
        //same string
        return true;
    }
    else
    {
        //not same string
        return false;
    }

    getchar();
}
