Thread: reading line by from file without fgets

I want to read from file line by line without using fgets. I have the following code but in the end crashes and i can not find the what is the problem

Code:

# include <stdio.h>
# include <stdlib.h>
int main(){
  char buf[60];
  int i=0;
  char ch;
  FILE *f;
  f=fopen("c.txt","r");
  if ( f== NULL ){ 
    printf("ERROR OPENING THE FILE");
        return(1);
   }
   while (!feof(f))
   {    
        do{
               ch=fgetc(f);
             buf[i]=ch;
            i++;
        }while(ch!='\n');
        buf[i-1]='\0';
        i=0;    
        printf("%s\n",buf);
    
   }
   fclose(f);
}
