Hi ,

i need help about passing the file path as parameter for fopen(), fread(), fwrite() functions or for FILE * pointer. How can I do that? i.e.

So, s should be a file path anywhere in disk not at the currnet folder so that I can enter a full file path not just the file name.

Any suggestion will be appreciated.

Thanks!

Nancy

Your question is a bit puzzling, as simple experimentation will yield the answer.

• If the file data.txt to be read is in the same directory as the executable, the file can be opened via:
  
  CPP / C++ / C Code:

  FILE *fp = open("data.txt", "r");

• If the file data.txt is in any other directory, it can be specified with a relative path:
  • eg. data.txt is in parent directory to the directory containing the executable:
    
    CPP / C++ / C Code:

    FILE *fp = open("..\\data.txt", "r");

• ...or the file can be specified with an absolute path:
  • eg. data.txt can be found as \Users\me\data.txt:
    
    CPP / C++ / C Code:

    FILE *fp = open("\\Users\\me\\data.txt", "r");

  ...which assumes that the application resides in a Microsoft filesystem. Since Microsoft uses a backslash ('\') as the directory delimiter, and the backslash is considered to be a meta-character in C/C++, Microsoft directory delimiters have to be escaped (doubled) to be represented correctly within the application.

A word of advice: do not use gets. If you want to know why simply google why is gets bad and you will get plenty of links. If you are not interested in the reason behind it and just want a safer method, investigate fgets instead.
