C# has a syntax feature where you can concatenate many data types together on 1 line.
string s = new String(); s += "Hello world, " + myInt + niceToSeeYouString; s += someChar1 + interestingDecimal + someChar2;
What would be the equivalent in C++? As far as I can see, you'd have to do it all on separate lines as it doesn't support multiple strings/variables with the + operator. This is OK, but doesn't look as neat.
string s; s += "Hello world, " + "nice to see you, " + "or not.";
The above code produces an error.
#include <sstream> #include <string> std::stringstream ss; ss << "Hello, world, " << myInt << niceToSeeYouString; std::string s = ss.str();
Take a look at this Guru Of The Week article from Herb Sutter: The String Formatters of Manor Farm
In 5 years nobody has mentioned
#include <string> std::string s; s.append("Hello world, "); s.append("nice to see you, "); s.append("or not.");
