C program to count the number of character ,number of lines from a text file

#include<stdio.h>
#include<conio.h>

void main()
{
int noc=0,now=0,nol=0;
FILE *fw,*fr;
char fname[20],ch;
clrscr();

printf("\n enter the source file name");
gets(fname);

fr=fopen(fname,"r");

if(fr==NULL)
{
   printf("\n error \n");
    exit(0);
}

ch=fgetc(fr);

while(ch!=EOF)
{
       noc++;
    if(ch==' ');
      now++;
    if(ch=='\n')
{
nol++;
now++;
}
    ch=fgetc(fr);
}
fclose(fr);


printf("\n total no of character=%d",noc);
printf("\n total no of words=%d",now);
printf("\n total no of lines=%d",nol);

getch();
