嗨Srini，


从代码中我看到ftell（pFile）将指向文件的开头，因此它的输出为0.这是因为你在fseek func中使用了SEEK_SET，它将带你到文件的开头。尝试在代码中将fEek调用中的SEEK_SET更改为SEEK_END，将光标移动到文件末尾。现在ftell（pfile）将为您提供将打印输出的光标值。


希望以下代码适合您。

Hi Srini,

From the code I see that ftell(pFile) will point to the beginning of the file and hence its ouput is 0. This is because you have used SEEK_SET in the fseek func which will bring you to the begining of the file. Try changing SEEK_SET to SEEK_END in the fseek call in the code which moves the cursor to the end of your file. now ftell(pfile) will give you the cursor value which will print the output.

Hope the following code works for you.
