Question

Here is my code.

#include<stdlib.h>
#include<stdio.h>
int main(int argc,char** argv)
{
    char a;
    a=9;
    FILE * fp;
    fp=fopen(argv[1],"r");
    while(a!= EOF)
    {
        a=fgetc(fp);
        printf("\n%d",a);
    }
}

The output to this is alright but at the end I am getting a weird character with -1 (since I am printing integer value.

How to stop it at EOF only?
Also what is this character?

Answer 1

Besides the methods in the other answers, you can also do like this:

while ((a = fgetc(fp)) != EOF)
{
    printf("%d\n", a);
}

Now you have a few alternative solutions. 🙂

Edit: As R.. so kindly reminds us, you also have to change the type of a to int.
