Hi guys, i compiled a program but i have this vague error message that occured. Searching through google.com states that it might be due to many problems such as invalid pointers, etc, etc. Im a fairly new person to C prog, so i would like to seek your advise on this. Can you guys tell me whats wrong with the code??

Main prog

I can't tell you, but I can tell you how to troubleshoot it:

1) Copy down the EXACT error message, for reference
2) comment out the calls to functions, one by one, until you find out which function is causing the error.

3) going into that function - comment out various lines, one by one, until you figure out exactly what line of code is giving you the error.

4) Check that out as thoroughly as you can

5) Still stuck, post THAT info back here, and we'll be able to help you more.

The troubleshooting described above is a basic programming skill, which you will have to learn - and learn well - if you're going to program.

"one by one" doesn't literally mean just one function or line of code at a time. You might do several at a time, and keep cutting the amount you're commenting out, down by half, each time you re-try.

Similar to a binary search algorithm. Same goal though - find the faulty line of code.

Hi, I have troubleshot the program. the readData() is working ok, but when i input the rest of the code it outputs a Segmentation fault. When i run the code without readData(), it works normally. However i cant find the exact code/line that causes the error. Any help on this? thanks

Hey, i actually solved the problem, indirectly. Because the txt file has an empty line below ( Line242), thats causing the error. So how do i change the readData() to retify this error? Many thanks

That's good. My compiler liked the program, (no errors or warnings), but also ran out of memory.

Empty lines can be detected by:

if(strlen(buffer)< 2)
  //line is one char - undoubtedly a newline char: '\n'
  break; //or continue; are common

Thanks Adak, Problem solved!
