Oh come on, I was taught the difference between strong and weak typing with C (weak) and Pascal (strong) as the examples 30 years ago. You can cast a C entity to something else and NO ONE ELSE KNOWS.
Then THINGS happen.
BAD things.
- unnouinceput 7y agoWhile Pascal is indeed strong typing and C is weak typing, casting is allowed on both at compile time and introducing bugs this way is not going to be stopped by compiler. Here is what a compile will behave in C vs Pascal: C code: int i = 1; char s = "1"; { if (i == s) //<--- this will be allowed by compiler in C because C is weak typing, and will comeback later to bite you at runtime { //bla bla } } Pascal code: var i : integer = 1; s : string = '1'; begin if i = s then begin //<--- this will not be allowed by compiler in Pascal because Pascal is strong typing //bla bla end; end.
