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.

Avoid new whenever possible. If you ever see delete in your own code in C++, you are doing something wrong. new should almost never be used, and when it is, it should be used with a smart pointer (that takes care of the delete for you). – …
