    string help

    Hello all,

    I am taking a line of text (lineOfText) and trying to insert and email address at a specific location (locationFound). I make a copy of the line of text, add the email address and copy the remaininder of the string from the copy. when I run this, it prints the lineOfText up to where I inserted the email address and then stops....

    Code:
    void createNewGorseveRecord(char lineOfText[], int locationFound) 
    {
       int i;
       int fieldLength=0;
       int startPos=locationFound;
       int lineLength=0; 
       char *emailaddr = test@aol.com;
       char copyLine[LINESIZE];
       fieldLength = strlen(emailaddr);
       lineLength = strlen(lineOfText); 
       printf("NEW LINE: %s \n",lineOfText); 
       strcpy(copyLine, lineOfText); 
       for (i=0;i<=fieldLength;i++) 
       { 
         lineOfText[locationFound] = emailaddr[i]; 
         locationFound++; 
       } 
       for (i=startPos;i<lineLength;i++) 
       { 
           printf("< %d %c \n",i,copyLine[i]); 
           lineOfText[locationFound] = copyLine[i]; 
           printf("> %d %c \n",locationFound, lineOfText[locationFound]); 
           locationFound++; 
       } 
       printf("NEW LINE: %s \n",lineOfText);
    When I print out each character I am copying from and too, it shows the correct character, then when my last line prints the lineOfText, it truncates to where I enter the new string, is this a buffer size problem?

    Code:
    for (i=0;i<=fieldLength;i++)
    Change the control field to i<fieldLength. e.g. from <= to <.

    The problem is you're copying the '\0' as well which is truncating the string. Changing the code that I just mentioned will fix it.
    If you understand what you're doing, you're not learning anything.
