		numbersFile << number<<"\n";	
	}
	//close the file "Numbers.txt"

	int evenCounter=0;
	int oddCounter=0;
	//After writing, check the file count all the even numbers and odd numbers written in the file. 
	ifstream numbersFileRead(fileName);
	if (numbersFileRead.is_open()){
		while (numbersFileRead>>number){
			if(number%2==0){
				evenCounter++;
			}else{
				oddCounter++;
			}
		}
		numbersFileRead.close();
	}
	
	
	//Display the count of even and odd numbers on the screen.
