Here you go:

#include <iostream>
#include <string>

int main(){

    std::string echo;
    std::getline(cin,echo);
    std::cout << echo;

}

I'm sure you can find one using Google somewhere.

We can only help you to do or understand stuff, we don't do homework.

Another shorter example:

#include <iostream>

int main()
{
    std::cout << std::cin.rdbuf();
}

Good luck trying to find why it works.
