sigh... why dosent this work?

After trying for 20 minutes with every possible way I could think of, I have come to seek expert advice lol....

What I'm trying to do with the code below is have a array of 100 strings (lines[100]), and with this, I want to periodicly add a new string to it, and bump out the oldest array off. (ex. lines[0] becomes lines[1]... lines[100] gets bumped off) If we run out of room. So in order to do that, I've created two for () {... statements... the first one copies the array to a templines array.. then the next one trys to move all arrays up one, leaving lines[0] for me to put the new data in... and lines[100] gets deleted. Now, when I try to run the code below in my program, I get an error and Borland C++ 3.1 closes with an error. Am I doing somthing wrong? Or, how would you do this? I have declared the char *lines[100]; in the begenning of the program....

// linecount = the current line the array is used up to

if (lineCount >= 100) {

char *templines[100];
for (int i = 0; i <= 99; i++) {
strcpy(templines[i], lines[i]);
templines[i] = newStr( lines[i] );
}

for (int i = 0; i <= 99; i++) {
strcpy(lines[i + 1],templines[i]);
}
strcpy(lines[0], "HI JON!\n");

} else {
lineCount++;
strcpy(lines[lineCount], "HI JON!\n");
}


Thank you!

... what are you saying about our expert skills? you doubt our judgement? a thousand firey birds with a thousand firey thunderbolts each attack your mother!

seriously...
i would suggest using the stl here. use vector classes. (and maybe string classes if you wish.
vector classes have the built in ability to increment, insert, delete, etc...

lol, well, thanks for the advice but I have no clue how to go about that... I'm not new to the programming scene, but to c++ I am ! lol, is there a example you could show me?

Thanks for you help!

Jon, you sure do laugh out loud a lot. :D

And, ygf, remind me never to get on your bad side... :(

Ouch! Poor mom!

Jon, try this:

Code:

---

struct CharLines
{
    char lines[100];
};

CharLines Lines[100];

//initial variable population
for(i=0;i<100;i++)
{
  strcpy(Lines[i].lines,"hello");
}

if(lineCount>=100)
{
    char newline[100], templine[100];
    strcpy(newline,"hi jon!");
    for(i=0;i<100;i++)
  {
      strcpy(templine,Lines[i].lines); //save current string
      strcpy(Lines[i].lines,newline);  //replace with new one
      strcpy(newline,templine);      //reset new one to former one
  }
}
