Using variables inside strings

Question

In PHP I can do the following    name    John    var    Hello   name            gt  Hello John   Is there a similar language construct in C    I know there is String Format    but I want to know if it can be done without calling a function method on the string

In C  6 you can use string interpolation   string name    John   string result     Hello  name      The syntax highlighting for this in Visual Studio makes it highly readable and all of the tokens are checked

Up to C 5  -VS2013  you have to call a function method for it  Either a  normal  function such as String Format or an overload of the   operator   string str    Hello     name     This calls an overload of operator      In C 6  VS2015  string interpolation has been introduced  as described by other answers

This functionality is not built-in to C  5 or below  Update  C  6 now supports string interpolation  see newer answers   The recommended way to do this would be with String Format     string name    Scott   string output   String Format  Hello  0    name     However  I wrote a small open-source library called SmartFormat that extends String Format so that it can use named placeholders  via reflection    So  you could do   string name    Scott   string output   Smart Format  Hello  name    new name       Results in  Hello Scott     Hope you like it
