fixed in C

Fixed the warning.

Exit code 132 is due to Swift crashing with *** Program crashed: Illegal instruction at 0x000055cd112cc93c ***. "Illegal instruction" in Swift are caused by failed preconditions, such as integer overflow or out-of-bounds accesses.

This one is caused by integer overflow in your while (c != 0) loop. You reverse the digits of c into m by successive multiplications of m by 10 and adding the last digit of c. This fails when c has as many digits as Int.max and ends with large digits, the last multiplication by 10 overflows.

I added better assertion messages to Swift.

All languages except COBOL and pending translations are now identical: no rounding, integer inputs. I will review pending translations, update, and approve them too. I will try to bring COBOL to the common form too, but I'll see how it goes :)

I will close this issue and raise a new one for COBOL if I won't be able to get it to work.

Python fork adding random tests.

Kata retired some time ago.

Haskell fork that fixes the random tests so that failed tests show the input strings along with some other minor improvements to test generation.

Author changed the link, close the issue

Added in Ruby, done in this fork

std::string o;
...
l = o.length();
char out[l];
...
return out;

• out is a local array variable. with return out; you are returning the address of a local variable, which is incorrect. as soon as the function exits the address becomes invalid.
• out is missing 1 byte for the nul-terminator

Ruby random tests added in this fork

Kata already retired.

Kata retired, translation was rejected.
