Program plan:

  • Declare header file.
  • Declare namespace.
  • Define the method “main ()”,
    • Declare the necessary arrays.
    • Declare the necessary variables.
    • Prompt the user to enter the file name.
    • Get the file name from the user.
    • Construct the input file stream.
    • Open the input file.
    • Check whether there is no file with the give name,
      • If it is true, print the invalid message.
      • Return “1”.
    • Print the string “INPUT”.
    • Get the character.
    • Execute for a character,
      • Print the character.
      • Check whether the character is alphabet,
        • Check whether the character is in uppercase,
          • Advances the uppercase character position.
        • Otherwise, advances the lowercase character position.
    • Print the string “SUMMARY”.
    • Execute loop for all lower and upper case letters,
      • Check whether the value is less than “26”,
        • Assign the value as “A”.
            • Otherwise,
              • Set the value as “a”-26.
            • Print new line.
    • Close the input file.
    • Return “0”.

Data Representation Part 3 HW3 1. Convert each decimal number to its 9's complement (use as many digits as shown): a) 73 b) 40512 c) 980034 d) Perform subtraction using 9's complement: 5042-671 2. Convert the following decimal numbers to the 10's complement: a) 128 b) 4097 c) 56020 d) Perform subtraction using 10's complement: 3205-4879 3. Perform the following multiplications. Assume that all values are unsigned numbers. (No problem with unsigned (always positive) numbers, just use the same standard techniques as in base 10.) a) 10112 × 01012 b) 011012 × 001112 c) 1100102 × 10112 d) 10110102 x 111012 4. Perform the following multiplications. Assume that all values are signed 2's complement numbers. a) 11002 01112 b) 00102 x 10102 - first multiply without sign-extending (show the wrong result), then redo with proper sign-extension. c) 111002 × 000112 5. Perform the following divisions. Assume that all values are unsigned numbers. a) 1011012 ÷ 1102 b) 1000112 ÷ 1012
From MATLAB Calculate the following scalars, matrices and vectors, using the matrices from problem 5. Outputs of the commands are required. (mean, sum, det, find, transpose (aka the apostrophe operator)
Modify the car purchase algorithm presented in class (on Chapter 1's slide set) so that the gasprice is no longer a constant, but instead it is subjected to an inflation of 5% yearly. Run thealgorithm and tabulate the costs year by year. (No need to program in C++ for this problemunless you really want to. You can use a spreadsheet or hand calculations.) Which car is abetter deal and by how much? Explain your algorithm welll.
