/prog/ - C reversing a string

Name: Anonymous 2012-10-29 12:00

Why does "printf("%c, reverse")" just put out "aggiN", but ("%s, reverse") outside of the loop put out "aggiNNigga" when it should do the same?

int main(int argc , char* argv [ ] ) {

    int i=0;
    int c;
    int a=0;
    char string[]="Nigga";
    char reverse[20];

    i=sizeof(string);
    printf("%d\n", (i-1));

      for(c=i-2;c>=0;c--)
      {
      reverse[a]=string[c];
      printf("%c", reverse[a]);
      a++;

      }
    printf("\n%s", reverse);
    return 0;
}

I know I had a brain fart, thinking about typeof, I was so embarrassed with the aberration I just said that I closed the computer and went outside

Now in D



string reverse(string str)

{

    import std.range;



    return retro(str);

}

Someone have the Fortran code to this?

try harder.

Symta:



reverse X = f [??@?] X

Haskell:



reverse = foldl (flip (:)) []

What the fuck are you trying to prove?

Here it is in APL: ⌽

According to your logic, APL is a better language than Symta...?

APL has an operator for reverse? Terrible!

If you think about it it's a very common operation, especially if you're doing purely functional tail-recursive stuff.

Write a tail-recursive lisp/scheme function that conses each element of a list with its position, i.e. (a b c) becomes ((a . 0) (b . 1) (c . 2)).

Contribooting Javascript.

function reverse(string){

    i=string.length;

    o="";

    while(i>-1){

        o+=string.substr(i,1);

        i--;

    }

    return o;

}

Even better Javascript.
