    Post Anagram

    I found an anagram program.. but it was designed for unix. Can someone help me convert it to windows? Or if someone has a better anagram algorithm?

    Code:
    ============================= canonize.c ===================================
    #include <stdio.h>
    #include <string.h>
    
    int charcmp(const char *c1, const char *c2) {
      return(*c1-*c2);
    }
    
    int main(int argc, char **argv) {
    char word[256], canon[256];
      for (;;) {
        if (gets(word) == NULL) break;
        strcpy(canon, word);
        qsort(canon, strlen(canon), sizeof(char), charcmp);
        printf("%s=%s\n", canon, word);
      }
      return(0);
    }
    ============================== gather.c ====================================
    #include <stdio.h>
    #include <string.h>
    
    int main(int argc, char **argv) {
    char line[256], lastcanon[256], lastword[256], *word;
      strcpy(lastcanon, "*Undefined*");
      for (;;) {
        if (gets(line) == NULL) break;
        if ((word = strchr(line, '=')) == NULL) break;
        *word++ = '\0';
        if (strcmp(line, lastcanon) == 0) {
          printf("%s = %s\n", lastword, word);
        }
        strcpy(lastcanon, line);
        strcpy(lastword, word);
      }
      return(0);
    }
    Also, will it take a long time to find all possible words using only 7 specifc letters on a P4 using this? Probably not but just curious.

    Thanks

    Looks like ANSI C to me. Compile away. Or did you mean with a fancy window and all that extra baggage?

    Hope is the first step on the road to disappointment.

    Is that supposed to be the same program or two seperate programs? Because if that's the same program it's not going to work due to main being defined twice.

    I made two differnet files and linked them into a project in Visual C++ (Ms). It gives an error which says that the Main method is already defined.

    There are two main methods in each file and I can't find what one has to do with another.

    Make two separate projects

    Suppose you have 7 letters, how does one find all possible words from those letters? I can be a two letter, 3 word?

    I know this is the C forum but let me just ask. If you are not oppossed to using some C++ STL functions/concepts, then there are some handy functions and containers that can make this a snap, i.e. the string and set containers and the next_permutation and sort functions in particular. Just a thought, no harm in asking is there? Only about 9 line of code.

    If not, one way to do this might be to have whatever function you have that jumbles the letters around also jumble around an extra space or NULL character in with the other letters. Then when it comes to printing, you print the whole string up to that space or NULL character. Thus you end up with output that may be one, two, three, etc. characters long based on where ever that space/NULL character got placed. Of course you may still end up with some strings output more than once. If for example the user wants to find all permutations of the word "back" then "ba<NULL>ck" and "ba<NULL>kc" would both be valid permutations of the original word but when output under this algorithm, you would see "ba" output twice. So, there are things to consider.

Whereas owners of cats are compelled to realize that, if you provide them with food and water and shelter and affection, they draw the conclusion that they are gods."
