Question

In Java

public int compareTo2(String that) {
    String sig1 = this.sort();
    String sig2 = that.sort();
    return sig1.compareTo(sig2);
}

In C++

int compareTo2 (string that) {
    string sig1 = this.sort();
    string sig2 = that.sort();
    return strcmp(sig1,sig2);
}

The first is a Java program. I translated it to C++ program. Did I write it correctly? Thank you.

Answer 1

Assuming that with string you talk of std::string:

std::string doesn’t provide a member named sort. You shall do that with std::sort:

std::sort(sig2.begin(), sig2.end());

And strcmp is thought to be used with const char*s, so you have to write:

return strcmp(sig1.c_str(), sig2.c_str());

Finally, this has to be dereferenced:

std::string sig1 = this->sort();
