Question about fopen

I am trying to open a file to write too but the user needs the ability to select what file they want to open. How do I use fopen to open a string and not a filename?

Just put it in the fopen function...

Code:

---

boolean file(char *filename)
{
        FILE *file;

        if ((file = fopen(filename, "w")) == NULL) {
                      return 0;
        }
        else
        {
                      //code
                }
}

thanks

Code:

---

int main()
{

        char *input, *output;
  FILE *ifp;
       
        printf("Which file would you like to read from?\n");
        scanf("%c", &input);
        if ((ifp = fopen(input, "r")) == NULL)
        {
                return 0;
        }
       
        printf("Which file would you like to write too?\n");
        scanf("%c", &output);
        if ((ifp = fopen(output, "w")) == NULL)
        {
                return 0;
        }



        return 0;
       
}

After the first scanf the program is exiting now. Sorry I am new too this.

input is a pointer, you need a character array

Code:

---

char filename[_MAX_PATH]; // in MS-Windows this is defined as 255
printf("Which file would you like to read from?\n");
// use fgets() instead of scanf so that you can enter filenames with spaces
fgets(filename,sizeof(filename),stdin);
// now open the file using the above filename.
if ((ifp = fopen(filename, "w")) == NULL)
{
        return 0;
}

Don't forget that fgets() leaves a '\n' at the end of the input string. You'll have to chop that off before using it in fopen().
