/*----------General Form of File reading operation----------*/
/*	1. Create a pointer pointing to a FILE structure.   */
/*	2. Assign the structure returned by                 */ 
/*		fopen("<nameOfFile>", "operationType")      
		 to the pointer created above.              */
/*	3. Create a variable of char datatype               
		to store each character of the file.        */ 
/*	4. Use a 'while' loop to read each character
		from the file by assigning the value of
			fgetc(<pointerToFile>) to the
				character variable.         */
/*	5. Use an 'if' inside the 'while' loop
		to check the characters 
			returned by fgetc() since
				fgetc() returns a macro 
					named 'EOF' when
						the last character of the file is read. Use this knowledge to break out of the 'while'.*/
/*	6. Close the file using fclose(<file pointer>)       */
