Assignment title: Information
This question is based on contents covered in Chapter 1 to 3 of text. The objectives of the question is to assess students’ on their setting up of the machine and running with the software and Course Team files correctly installed, if any. ability to declare variables with the suitable data type. understanding of selection construct and repetition construct
(a) The purpose of this part of the question is to ensure that you have installed MS Visual C++ Express Edition and to get you familiar with the steps in writing, compiling and running a C++ program using the installed software.
(i) After you have installed MS Visual C++ Express Edition and registration on your machine, you are ready for the next step. (ii) Create a new empty project. Please refer to . Name this cpp code file as ABCQ1a.cpp where ABC denotes the initials of your name. (iv) Copy and paste the following code to this empty source code file.
#include #include using namespace std;
int main() { int m = 8; // Line 1 float k = 2.5; // Line 2 double j = 22/7; // Line 3 cout << "(a) " << m << " "; cout << "(b) " << m++ << "\n"; // Line 4 cout << "(c) " << --k << endl; // Line 5 cout << "(d) " << (k + 1) << "\n\n" ; cout << "(e) " << 1 + m << endl << endl; cout << "(f) " << k << endl; cout << fixed << setprecision(2) // Line 6 << "(h) " << j << endl; cin.ignore();// this line is optional }
Table 1.1
(v) Compile and run the program. (vi) Capture the output screen of the run. You can do this by using the Print Screen facility. Your keyboard should have a key labeled Print Screen or Prt Scr which can capture the contents of the active window. Pressing Alt+Print Screen will copy an image of the active window to the clipboard. (vii) Open MS-Word and then choose Edit|Paste to copy the clipboard contents into the blank document. (5 marks)

(b) Describe the data types indicated in Line 1 to Line 3 of the program in Table 1.1. (3 marks)
(c) Explain the statement in Line 6 of the program in Table 1.1.
(3 marks)
(d) Study the increment and decrement operator used in Line 4 and Line 5 of the program in Table 1.1. Explain how the line of code works using the respective operator. (3 marks)
(e) Demonstrate your ability to use C++ syntax to develop code after examine of the given data in Table 1.2 and requirements.
The program which uses a loop to prompt the user to enter the customer ID, sales amount and discount rate, computes and accumulates the net amount if the entered sales amount is more than S$10000. The loop is control via the sentinel value, ‘E’. At the end of the loop, the program displays the total net amount with 2 decimal places. See sample output. The net amount of each customer is computed using the following formula: Net amount = (1-Discount Rate/100) * Sales Amount
