Program
a='222';
b='333';
print b+a;
a='EMER';
b='GING';
print a+b;
Because both values are strings, b+a prints 333222 rather than adding the numbers, and a+b prints EMERGING. To check how many characters a joined string ends up with, paste it into our string length counter; more small helpers for programmers are in the free online tools collection.
