c++ - "printf" on strings prints gibberish

Question

I'm trying to print a string the following way:

int main(){
    string s("bla");
    printf("%s 
", s);
         .......
}

but all I get is this random gibberish.

Can you please explain why?

Answer 1

Because %s indicates a char*, not a std::string. Use s.c_str() or better still use, iostreams:

#include <iostream>
#include <string>

using namespace std;

int main()
{
  string s("bla");
  std::cout << s << "
";
}
