statement

Here is () statement fgetc function.

Examples

The following example demonstrates the fgetc () function is used.

#include <stdio.h>

int main ()
{
   FILE *fp;
   int c;
   int n = 0;
  
   fp = fopen("file.txt","r");
   if(fp == NULL)

          break ;
      }
      printf("%c", c);
   }while(1);

   fclose(fp);
   return(0);
}

Suppose we have a text filefile.txt, it reads as follows.As an example of the file, enter:

We are in 2014

Let's compile and run the above program, which will result in the following:
