Let's discuss the subproblems one by one. In the second subproblem, we will find the element that uses the minimum number of segments to display a number.In the first subproblem, we will compute the minimum number of segments required to display a number.The problem is divided into the following two subproblems. Return ntainsKey(digit) ? encodings.get(digit) : 0x00 Private static void lightSegment(boolean on, String onValue, String offValue) the function decides which segment to be on or off print method that computes how many segments are required to print a digitĬhar bits = String.format('%7s', Integer.toBinaryString(code)).replace(' ', '0').toCharArray()

calling the print method that prints the digit on the console loop runs from 0 to 9 and print digits one by one by invoking the print method key-digit, value-hexadecimal encoding for displaying the digits 0 to 9 (in abcdefg sequence) static block that stores key and corresponding values to the Map Private static final Map encodings = new HashMap() Let's implement the above logic in a Java program. In the table on represent, 1 and off represents 0. In the following Java program, we have used hexadecimal encoding to represent a digit in seven segment form. Let's see another way to print digits in seven segment display. Public static void main(String args) throws Exception If LCD1 sends an overflow message -> increment LCD2. The underflow or overflow messages can be used to couple multiple LCDs together very simply. This allowed a very simple code to update the UI feedback and to update the edit box that mirrored the current numbers. I used Windows message mechanism to send a message when the LCD has changed. The wparam contains the control id of the LCD that sent the message. Void CTimectrlDlg::lcd_change(WORD wparam, LONG lparam) (make sure the messages are unique in your app, or us RegWndMsg) The LCD will send the following messages to your dialog (its parent) M_lcd.SetFgColor(RGB( 12, 12, 12)) //use your colors In the IntDialog() function of the parent, you may set operational parameters such as:

wizard and rename the declaration in your header from CStatic to Clcd7 rename its ID to something other then IDC_STATIC.

Just create a Static Control in the Dialog Editor,
