Thread: error in code

in this code, i''m trying to view data already present in a file on the screen.but i keep getting an error like "error: expected '=' , ',' , ';' , 'asm' or '__attribute__' before * token" at the file declarations

Code:

extern void ygs_turkce(void);

extern void ygs_kimya(void);

extern void ygs_geometry(void);

Did you #include <stdio.h>?

First of all lose all those extern keywords... every last one of them.

If your main is below these functions... you also don't need the declarations at the top.

Next move your FILE* declaritors into the functions, not at global scope.
Test each file to see if it actually opened or not.
Don't use fscanf() twice for each line... simply because you'll end up only seeing every other entry.
fscanf() will never return END... it might return EOF, but only after reading the last line twice.
If you want to see the stuff on the screen you've got to put it on the screen.
And... you need to close your file when you're done with it.

For Example:

Code:

void ygs_matematik(void)
{
    FILE *fygsturkce;
    char mat[1000];

    fygsmatematik=fopen("YGS_matematik.txt","r");
    if (!  fygsmatematik )
     {
        printf("Could not open YGS_matematic.txt\n");
        return;
     }

    while(fscanf(fygsmatematik,"%s",mat) > 0)
       printf("%s \n", mat);
 
    fclose(fygsmatematik);
}

However... since these are all doing the exact same thing, just with different files you could just as easily make one function that does it all...

Code:

void DisplayFile(char *FileName)
{
    FILE *fptr;
    char buf[1000];

    fptr=fopen(FileName,"r");
    if (!  fptr)
     {
        printf("Could not open %s \n",FileName);
        return;
     }

    while(fscanf(fptr, "%s", buf) > 0)
       printf("%s \n", buf);
 
    fclose(fptr);
}

And call the function with different file names...

Code:

// in your main function...

DisplayFile("YGS_matematik.txt");
DisplayFile("YGS_kimya.txt");
// and so on

Hint: Always look for the simplest way to do things!

thank you.it worked
