Example 1: how to concatinate two strings in c++

std::string moretext = "there";
std::string together = text + moretext;
std::cout << together << std::endl;

Example 2: how to merge string array in C++

For string concatenation in C++, you should use the + operator. std::string nametext = "Your name is " + name; where operator + serves to concatenate strings. nametext is an std::string but these do not have the stream insertion operator ( << ) like output streams do.
