Thread: question

  1. #1


    I just need some guidance about two things please

    1. Is reversing a string same as swaping it???
    can one use swap function for this purpose?

    2. I was supposed to alphatize the strings, and I used 'atof' and 'atoi' functions simultaneously. My compiler gave me some weired errors and didn't compile. I couldn't even undrstand those errors. Did I use the right functions??

    any kind of help is appreciated

    void main()
    char *m;
    char i,char1,char2;
    printf("your message:");
    it was for your first question
    i hope it's ok

    and for your second question
    you can use strcmp func. (string.h)
    it compares the strings with their ascii values

    if str1 < str2 --> it returns a negative value
    if str1 = str2 --> it returns 0
    if str1 > str2 --> it returns a positive value

    Thanx kdt,
    I understand the first answer, but for the secong one, I'm supposed to alphabetize the strings. Like

    as if i have 4 strings. My job is to put those 4 strings into alphabetical order and renumber them appropriately.

    Please don't think that I don't wanna do my homework; I have been trying & trying, but I'm not a good programmar. Thank you very much for your anticipation.

    you can use an array for the strings
    and for example bubble sort to sort them
    think them like an integer but use strcmp() to sort them
