nametext is an std  string but these do not have the stream insertion operator   lt  lt   like output streams do   To concatenate strings you can use the append member function  or its equivalent      which works in the exact same way  or the   operator  which creates a new string as a result of concatenating the previous two

First of all it is unclear what type name has  If it has the type std  string then instead of  string nametext  nametext    Your name is   lt  lt  name    you should write  std  string nametext    Your name is     name    where operator   serves to concatenate strings   If name is a character array then you may not use operator   for two character arrays  the string literal is also a character array   because character arrays in expressions are implicitly converted to pointers by the compiler  In this case you could write  std  string nametext   Your name is      nametext append  name      or  std  string nametext   Your name is      nametext    name

You can combine strings using stream string like that    include  lt iostream gt   include  lt sstream gt  using namespace std  int main         string name    Bill       stringstream ss      ss  lt  lt   Your name is     lt  lt  name      string info   ss str        cout  lt  lt  info  lt  lt  endl      return 0
