	int numberFourLetterWords=0;
	FILE *ptrFile;
	if ((ptrFile = fopen("TRIAL.txt", "r")) == NULL) {
		printf("Error! File cannot be opened.");
		exit(1);
	}
	 while (fscanf(ptrFile,"%s",word)!= EOF) {
		numberWords++;
		if(strlen(word)==4){
			numberFourLetterWords++;
		}
    }


	printf("The number of words contained in the file: %d\n",numberWords);
	printf("The total number of four letter words in the text file: %d\n",numberFourLetterWords);
