Number of characters in the statistics file (with command line arguments)

#include <stdio.h>
#include <stdlib.h>
int main (int argc, char *argv[])
{
Char ch;
FILE *FP;
Long count=0;

if (argc!=2)
{
printf ("File name is:%s\n", argv[0]);
Exit (Exit_failure);
}
if ((Fp=fopen (argv[1], "r+") ==null)

Exit (Exit_failure);
}
while ((CH=GETC (FP))!=eof)
{

++count;
}
Fclose (FP);
printf ("File%s has%ld characters\n", argv[1],count);
return 0;
