Boolean: Case

Software Language Rosetta Stone

For those of us that program in too many languages

Language

Type Delphi/Pascal perl C Basic bash Java Notes
Statement
terminators		 ; ; ; New line ; 1
Assignment := = = =
Block
Comment		 { comment }

(* comment*)

 /* comment */ /* comment */
Line comment //comment # //comment 
1 - Strictly speaking, Delphi doesn’t have Statement terminators; it has
statement separators.  That’s a distinction that, if K&R had known
about when writing the C language we wouldn't have ugly things like:
if (expression)
   a = b;
else
   c = d;
That first “;” is because C uses terminators.

Blocks, and loops Loops

Type Delphi/Pascal perl C Basic bash Java
Program block begin
statement 1;
statement 2
end		 {
statement 1;
statement 2;
}		 {
statement 1;
statement 2;
}
if then else if expression then statement
else statement;		 if (expression) then
statement
else
statement
For loops for I := 1 to 10 do statement; for (int I=1; I<=10; I++) statement; for (int I=1; I<=10; I++) statement;
Reverse For loop for I := 10 downto 1 do for (int I=10; I>=1; I--) statement; for (int I=10; I>=1; I--) statement;

Need to add: 

Mention of structures, arrays, lists, sets. (Delphi has structures (records), arrays, sets, but I don’t think it has lists). C has structures (structs) and arrays Objects.
