fscanf: works exactly like the scanf() function except that it reads from the stream

    

//Header file:     #include <stdio.h>  
//Declaration:     int fscanf(FILE *stream, const char *format, ...); 
//Return:          returns the number of arguments actually assigned values or EOF on failure.

  int main(void)
  {
    FILE *fp;
