also this is my source code to get values from text file and put them in struct . Have done everyting that I know but can't access back what I put in struct truely . I'm newbie at here and C so someone would give a hand ?
I calculated their sizes with endlines doing ignore lines includes strings like "END" . Then allocated struct objects with their sizes before getting values from text source line by line .
So so how can I access them truely ?
Because of sizeof(block1) is different with sizeof(blocks). Let try to replace in your print function.
