At the end of the last line, you have a new line character, which is not read by >> operator and it is not an end of file. Please, make an experiment and delete the new line (thelast character in file) - you will not get the duplication. To have a flexible code and avoid unwanted effects just apply any solution given by other users. At the end of the last line, you have a new line character, which is not read by >> operator and it is not an end of file.

The ReadFile function checks for the end-of-file condition (EOF) differently for synchronous and asynchronous read operations.

feof() function is used to validate whether end of file is reached. I am trying to read an unknown amount of lines from an input file and basically stop when I reach the EOF. I probably does'nt matter but the assignment is to create a simple lexical analyzer/scanner for a mini-subset of Pascal. Long story short, I need to read character at a time until either my buffer is full or I reach the end-of-line symbol. fseek() functions is file handling functions in C programming language.
