deleting numbers in text files

HI people,

I am trying to delete numbers from any text file. I have this much so far:

Code:

---

int main(){
    char c, filename[10]; FILE *fp;
        printf("Eneter a filename");
        scanf("%s", filename);
        if((fp=fopen(filename, "r")) !=NULL){
              while ((c=fgetc(fp)) !=EOF)
                        fputc(c, stdout);
        }       
        else{

                  printf("could not open file ", filename);
        }
        if (isxdigit(fputc(c, stdout))){
printf("\nThere is a number");
        }
        else
        {
printf("\nThere are no numbers");
        }

 printf(" \nEnter a filename");
        scanf("%s", filename);
}

---

The files opens, and compiles but it does not match numbers.
Can anyone help
thanks

If you want to check whether c is a numeric character, you probably need to do that before you destroy it (by reading the next character).

Note that c should be of type int to correctly check the EOF condition
