As I mentioned, I’m learning/employing a bunch of varied programming languages. In fact, I’m employing several programming languages within a single project. While tabbing betwixt editor windows I’ll often miss tabbing between programming languages. Fortunately, error codes are as they are and they yell at me promptly.

To review, concatenating strings:

Javascript

var mystring = string1 + " is " + string2;

Ruby and Python

mystring = string1 + " is " + string2;

PHP

$mystring = $string1." is ".$string2;

C

char mystring[50], string1[10], string2[10];

strcat(mystring, string1);
strcat(mystring, " is ");
strcat(mystring, string2);

C++

string mystring, string1,string2;
mystring = string1 + " is " + string2;

Feel free to add any more you know.
