	int i=0;
	my_file.open("text.txt");
	if (!my_file) {
		cout << "No such file";

	else {
		double n;
        
		while (1) {
			my_file >> n;
			num[i]=n;
			if (my_file.eof())
				break;
			i++;
		}


	}
	double min=num[0];
	double max=num[0];
	for(int j=0;j<=i;j++){
	    if (num[j]<min)
	        min=num[j];
	}
	for(int j=0;j<=i;j++){
	    if (num[j]>max)
	        max=num[j];
	}
	cout<<"\nSmallest: "<<min;
	cout<<"\nLargest: "<<max;
	my_file.close();
	return 0;
