Open file by its full path in C++

Question

I want the user to give me the full path where the file exists and not just the file name. How do I open the file this way?

Is it something like this:

if         


        

Answer 1

The code seems working to me. I think the same with @Iothar.

Check to see if you include the required headers, to compile. If it is compiled, check to see if there is such a file, and everything, names etc, matches, and also check to see that you have a right to read the file.

To make a cross check, check if you can open it with fopen..

FILE *f = fopen("C:/Demo.txt", "r");
if (f)
  printf("fopen success\n");
