This is the source code

#include <RInside.h>                    // for the embedded R via RInside
int main(int argc, char *argv[])
 {
   RInside R(argc, argv);              // create an embedded R instance
   R["txt"] = "Hello, world!\n";       // assign a char*
(string) to 'txt'
   R.parseEvalQ("cat(txt)");           // eval the init string,
ignoring any
returns
   exit(0);
}
