Given two integer variables distance and speed, write an expression that divides distance by speed using floating point arithmetic, i. e. a fractional result should be produced. 1. Calculate the average (as a double) of the values contained in the integer variables num1, num2, num3 and assign that average to the double variable avg. Assume the variables num1, num2, and num3 have been declared and assigned values, and the variable avg declared.
Creating objects
2. Declare a reference variable of type File named myFile.
3. Declare a variable named myMenu suitable for holding references to Menu objects.
4. Suppose a reference variable of type File called myFile has already been declared. Create an object of type File with the initial file name input. dat and assign it to the reference variable myFile.
invoking methods

Write a new lc-3 trap subroutine (i.e. a subroutine that will be invoked via the trap instruction) that will receive a numeric digit entered at the keyboard (i.e. an ascii character), echo it to the screen, and return in r0 the corresponding numeric value: so if the user types the digit '7', the character '7' will appear on the screen, but the value returned in r0 will be b0000 0000 0000 0111 (#7) you may not use any trap calls in your code - you must implement the "polling" code that interrogates the keyboard status and data registers. ; getnum_tsr ; a subroutine for obtaining a numeric value ; given ascii numeric digit input to keyboard. ; the numeric digit is echoed to the console (e.g. '7' = b0000 0000 0011 0111), ; but the value returned in r0 is the actual numeric value ; corresponding to the digit (e.g. b0000 0000 0000 0111 =
