File Management in C

The question:Why do i have to write if(c!=EOF) statement again in do-while block in the following code?

The thing is that if i don't write the if(c!=EOF)again in the block,it outputs the last word again in the end.Can you tell me why that is happening?

Code:

---

#include<stdio.h>

main()

{
       
        FILE*pt;
        char array[100];
        int c;
        pt=fopen("text.txt","r");
        if(pt==NULL) printf("the file doesn't exist");
        else {
                do {
                        c=fscanf(pt,"%s",array);
                        if(c!=EOF)
                        printf("%s",array);
                } while(c!=EOF);
               
            }
           
        fclose(pt);
       
}

Because you're not using EOF consistent with the way it actually works.

Checking for EOF works exactly the same way as feof() (that is to say: it doesn't).

I didn't understand you.English is not my native langauge.So can you be clear?

Read the link he has provided.

Your question is "why do I need to check if I've reached the end of the file before I go off assuming I haven't?"

Here's a similar algorithm for walking through a doorway:

1. Approach the door
2. Walk through the door
3. Check whether the door is open

Hmm...

What does fscanf function return here?

You are saying is it because of do-while statement?

First do then check?

I tried with normal While.It still has that problem.
