Simple Question C++ Strings

A quick question... How to add one string to another in c++, example....

"The Cat"
"The Dog"
"The Mouse"

I want to add these strings together to get one string...

"The Cat\nTheDog\nTheMouse"

This is what i want to do in psedo-code style...

Code:

---

string one;
string two;
string three;
string output;

output = ???

return output;

---

Code:

---

#include <string>
#include <iostream>

int main(void)
{
        std::string s1 = "The Cat",
                                s2 = "The Dog",
                                s3 = "The Mouse";

       
        std::string out = s1 + '\n' + s2 + '\n' + s3;

        std::cout << out << std::endl;

        return 0;
}

---

Thanks!!! ...Just one more quick question... How do I do a string compare in C++, because its an object, can i just do...

Code:

---

str::string1;
str::string2;

if (string1 == string2) {
  return 0;
}
else {
  return 1;
}

---

Code:

---

str::string1;
str::string2;

---

Yes! ...except for how you've declared the variables.

HA!!! Oh yeah!!! ...typo error!! Cheers!!!!

Code:

---

std::string out = s1 + '\n' + s2 + '\n' + s3;

---

That should be

Code:

---

std::string out = s1 + "\n" + s2 + "\n" + s3;

---

or am I wrong?

It's a newline character, either way is fine.

Operators are overloaded for both chars and char arrays, in std::string. I believe using char is actually faster, since you're only passing (and copying and stack-pushing) a byte, and the string doesn't need to iterate over the chars to find the elusive '\0'.
