Hi, Ive tried your tutorial and gor the first half right, however when I do the second part, it goes out as "NULL" not "Hello World". Is there some way I can print it out right?

How can I create and save a file, so that it will work on any Win 10 computer? Trying to create and populate a text file, but cannot save to C: nor to C:\USERS. I need this to work on any computer, and these 2 areas are common to any Win 10 computer.

How to edit the file text anywhere we want?

Quick tip for everyone. When using write ('w') mode in fopen, it will overwrite the file each time. If you want to append to a file, use ab. So:

fp = open("example.txt", "ab");

I have to give a thumbs down to this video because it does NOT work ! I believe the author is leaving something out. I have tried the recommended code:
#include <stdio.h>
main()
{
FILE *fp;
fp=fopen("filename.txt", "w");
fprintf(fp, "%s", "Hello world");
fclose(fp);
but I end up getting a "segmentation" error. I believe the restriction is due to the restrictions that Microsoft Windows is imposing on my PC desktop. Peraps the code works for some operating systems other than Windows.
