Ok, there are special characters in your file, so the issue is probably the way you saved it with Excel. Try exporting the Excel file as CSV (Comma Separated Values) even if you name the file with a

由于在数值仿真计算和信号处理时,大家在数据的存取上以txt和dat文件为主,且读取比存储更麻烦(存储的话fwrite,fprintf基本够用),因此下面的讨论主要集中在“txt 文件的读取”上(dat文件和txt文件类似)。 一. 基本知识: 1. 二进制文件与文本文件的区别:
