Nettet1. jan. 2004 · 1 I have a txt file with thousands of lines. Length of each line varies. The txt file mainly contains hex data in bytes. For example: 01 01 04 03 = 4 bytes. Second line might contain 8 bytes, 3rd 40 bytes and so on. There are thousands of such lines. Now I want to read these bytes into int buffer. 1 It's taking the address of buffer, casting it to int *, then dereferencing the resulting pointer, which is undefined behavior. In particular, there is no guarantee that buffer is aligned on an accept int boundary. The behavior is undefined. You should not attempt to run this code. – Tom Karzes May 11, 2016 at 6:59 Add a comment 4 Answers
