Thread: Character in a String

I would do

Code:

void ShortenFileName(char *fname, char *sname)
{
     int iIndex=0;

     while((fname[iIndex] != '.' )&&( fname[iIndex] != '\0' ))
     {
         sname[iIndex]=fname[iIndex];
         iIndex++;
     }
     sname[iIndex]='\0';
     return;
}

or

Code:

void ShortenFileName(char *fname, char *sname)
{
     char    *pString=NULL,*pLastSlash=NULL;
     
     //find the first \
     pString=strstr(fname,"\");
     if(pString!=NULL)//found one look for more
     {
        do
        {
             pLastSlash=pString;
             pString=strstr(pString,"\");       
        }
        while(pString!=NULL)
        pLastSlash++; //now should be just after last back slash
     }
     else  pLastSlash=fname[0]; //no back slash so set to start
     pString=sname[0];
     while(pLastSlash != '.' )&&( pLastSlash != '\0' ))
     {
         *pString++=*pLastSlash++;
     }
     return;
}

(or something on these lines, I have not tested this)

Remember that you must write '\\' instead of '\'.

The pointers are incremented so one string is copied into the other and the while has something new to test. They are just an index to each string.

I think that you need to use a pointer if trying to make an element of a string array = another char variable.

Or

as the char not terminated may read past the single character into the next memory location. (treats the char "c" as an array ie string)
