Question

So here is my attempt at it but I’m getting a few errors which I don’t know how to fix.
17.2 Warning : passing argument 2 of putc makes pointer from integer without a cast.
C:\mingw ……. note expected Struct FILE* but’ but argument is of type int.

  #include <stdio.h>
  #include <stdlib.h>

  int main (void) {
FILE *fp;
int c;
char copywords;

fp = fopen("gues20.txt", "r");
if (fp == NULL)
exit(1);

c = getc(fp);
while(c != EOF)
{
putc(c, copywords);
c = getc(fp);
}
printf("%d", copywords);
}

Answer 1

Second argument to putc is a file stream. But you pass a plain charcter. Use:

while(c != EOF)
{
putc(c, stdout);
c = getc(fp);
}

to print in stdout.
