July 27[edit]

Java![edit]

Hi guys, can you help me figure out how could the first line of the output was correct and the others were not? Thank you! Deep humility (talk) 19:06, 27 July 2020 (UTC)[reply]

// Print a conversion table of inches to meters.
// Display 12 feet of conversions, inch by inch. 
// One meter equals approximately 39.37 inches. 

/* 1 inch = feet =  meters;
 * 2 inches = feet = meters;
 * 3 inches = feet = meters;  
 * n inches = n feet = n meters;
 * 
 * 144 inches = 12 feet = meters;
 * */

/* 1 meter = 39.37 inches. 
 * 
 * (1/39.37) meter = 1 inch. 
 * */

/* 1 feet = 12 inches; 
 * 
 * (1/12) feet = 1 inch;
 * */

/* 1 inch = (1/12) feet = (1/39.37) meters;
 * 2 inches = 2 * (1/12) feet = 2 * (1/39.37) meters;
 * 3 inches = 3 * (1/12) feet = 3 * (1/39.37) meters;  
 * n inches = n * (1/12) feet = n * (1/39.37) meters;
 * 
 * 144 inches = 12 feet = 3.6576 meters;
 * */


	public static void main(String[] args) {

		// TODO Auto-generated method stub

		int counter = 1;
		int n = 1; // multiple;

		for (int inch = 1; inch < 145; inch++) {

			float feet = (float) ((n) * (inch / 12.00));
			float meter = (float) ((n) * (inch / 39.37));

			if (inch == 1) {

				System.out.println(inch + " inch is " + feet + " feet or" + meter + " meters.");

			} else {

				System.out.println(inch + " inches equal " + feet + " feet or " + meter + " meters.");

			}

			n = n + 1;


		}

	}

Output:

1 inch is 0.083333336 feet or 0.02540005 meters.

2 inches equal 0.33333334 feet or 0.1016002 meters.

3 inches equal 0.75 feet or 0.22860046 meters.

4 inches equal 1.3333334 feet or 0.4064008 meters.

5 inches equal 2.0833333 feet or 0.63500124 meters.

What is "n"? Why are you incrementing both inch and n? -- Finlay McWalter··–·Talk 19:17, 27 July 2020 (UTC)[reply]

Solved:

What a careless mistake! I ignored that inch is incremental due to inch++. 😳😳😵😵😬😬😱😱 Deep humility (talk) 19:19, 27 July 2020 (UTC)[reply]

User:Finlay McWalter, I modified my code a bit and the output appeared to be correct now. Thank you for your attention and enlightenment! Deep humility (talk) 19:21, 27 July 2020 (UTC)[reply]

Nitpicking: one meter is not 39.37 inches. Instead, one inch is defined to be exactly 0.0254 meters and one foot is exactly 0.3048 meters. 93.142.89.209 (talk) 22:02, 27 July 2020 (UTC)[reply]

To be fair, 1 m was exactly 39.37 inches in the US... until 1959 when the inch was redefined. See Foot (unit)#Definition. --174.89.49.204 (talk) 22:42, 27 July 2020 (UTC)[reply]

Indeed it was. One learns something new every day! 93.142.89.209 (talk) 04:25, 28 July 2020 (UTC)[reply]

Oh! Thanks for the information. I was just using my reference e-book's tip! Deep humility (talk) 15:42, 28 July 2020 (UTC)[reply]

Your code is correct now, but note also that you don't need the variables counter and n for anything. JIP | Talk 10:36, 28 July 2020 (UTC)[reply]

Ahh, yes, you are right. Thank you! Deep humility (talk) 15:42, 28 July 2020 (UTC)[reply]
