How to open file inside folder in current directory using fopen

Question

I want to open a file that is inside a folder in the current working directory like so:

fopen("/folder/file.txt","r");

I'm unable to do so in this way, i get a "No such file or directory" error.

How can i do this properly?

Thank you in advance for any help.

Answer 1

You have to mention that is a current directory. Try this,

fopen("./folder/file.txt","r");

Or

fopen("folder/file.txt","r");

If you mentioning like this /folder/file.txt it will search the directory from the root directory. So this is the reason for getting the error.

Answer 2

Try:

fopen("./folder/file.txt","r"); /* dot means the directory itself */

or

fopen("folder/file.txt","r"); /* without the first backslash */

Answer 3

It seems that if i remove the first backslash it works.

Like so:

fopen("folder/file.txt","r");

weird.
