    Need help capitalizing characters in a strong

    I'm trying to get to where the first letter of each word of the "description" is a capital letter while the rest is a lower case letter. So far, I'm not even able to successfully get every letter lower case. What am I doing wrong?




    Code:
    #include<stdio.h>
    #include<stdlib.h>
    #include<ctype.h>
    #include<string.h>
    
    
    #define STORE "Sierra Sporting Goods"

    #define MAXPROD 9999
    #define MINTYPE 1
    #define MAXTYPE 5
    #define MINQUAN 1
    #define MAXQUAN 50
    #define MINCOST 5.00
    #define MAXCOST 900.00
    #define MINPRICE 6.00
    #define MAXPRICE 1000.00
    #define TRUE 1
    #define FALSE 0

    Ok, please re-edit your code to inlcude code tags and make sure it's indented in a readable style...

    So far, I was able to get to strcase() funtion to work by changing it from a void to a char. I just need help at this point to get the words to look like this:

    Blah Blah Blah

    (and not like)

    bLAh bLAH BLAh

    Code:
    char strcase(char description[])
    {
         int i;
         
         
          for (i = 0; i < strlen(description); i++)
    	{
    		description[i] = tolower(description[i]);
    	}
     return(description);
    }
    The mistake in the get(description) was from lack of understanding, I guess. I don't know.

    You shouldn't use gets. Your problem is here however:
    Code:
    void strcase(char description[])
    {
         int i;
         
          for (i = 0; i < strlen(description); i++)
    	{
    		description[i] = tolower(description[i]);
    	}
          gets(description);
    }
    After you lower the string, you immediately overwrite it by prompting them to enter the description again.

    edit - beaten to the punch

    Quzah.
    Hope is the first step on the road to disappointment.

    You also don't need to return description. Technically you can't return an array.

    Try this...
    Code:
    void strcase(char description[])
    {
         int i;
         for (i = 0; i < strlen(description); i++)
           {
              description[i] = tolower(description[i]);
            }
    }
    You are passing in the pointer to your description. The function will edit it in place.

    One tip, as a matter of efficiency, it is very slow to have your loop recalculate strlen() on each iteration...
    Code:
    void strcase(char description[])
    {
         int i;
         int len = strlen(description);
         for (i = 0; i < len; i++)
           {
              description[i] = tolower(description[i]);
            }
    }
    It probably won't make a noticeable difference on short strings... but on long ones it makes quite a difference.

           {
              description[i] = tolower(description[i]);
            }
    }
    That definitely helped it all work efficiently. Now how would I find the first letter of each word and change it to a capital letter?

    Give this a look.... capitalizing only first letter in strings??

    Are you guys in the same class?

    How do you know when a new word starts?

    AHEM... Did you not see my original example?

    C'mon... put thinking cap on before applying fingers to keyboard!
    If you're talking about this code, then wouldn't it just lower case every letter?
    Code:
    void strcase(char description[])
    {
         int i;
         for (i = 0; i < strlen(description); i++)
           {
              description[i] = tolower(description[i]);
            }
    }
    How do you know when a new word starts?
    That's what I'm not sure about. I was thinking about finding the first letter of the string array description[0] and forcing that to be capitalized then finding where there's a space and capitalizing the next letter. However, I do not know what code i would use to find to letter with the space.

    No, sorry... there are two almost identical threads running. I posted an example in the other one and then promptly lost track of who's who...

    Take a look at this...

    That thread definitely helped me. Now i have the very first word capitalized, but I'm messing up getting each new word capitalized


    Code:
    void strcase(char description[])
    {
         int i;
         for (i = 0; i < strlen(description); i++)
           {
              description[i] = tolower(description[i]);
            }
        while (description[i] = ' ')
        {
              ++i;
             description[i] = toupper(description[i]);
    }
               description[0] = toupper(description[0]);
    }
    I just need help with the while function in there. What am I doing wrong?

    Did you see this?

    Code:
    void strcase(char *str)
      { int x, y;  // loop variables
         char *ucp;  // upper case pointer 
         y = strlen(str);
         // convert to all lower case
         for( x = 0;  x < y; x++)
           {  str[x] = tolower(str[x]); }
        // capitalize words
       str[0] = toupper(str[0]);
       ucp = str;
        while (ucp = strchr(ucp,' '))
           { ++ ucp;
               *ucp = toupper(*ucp);}  }
    The key to making it work is the strchr function, you chose not to include...

    Honestly, I don't know how to make the pointer ucp work.
