Read all of what follows…

1. In Q1, I have given you a list of words that a complete explanation would use. Failure to use any of these words will result in a loss of points.

   Where it says "assign / assigns / assigned / assignment", you only need to use one; I could not anticipate how you would choose to phrase the relevant sentence. Similar comments apply to "display", "convert", and "truncate".

2. In Q2, I have asked for regular status updates on the contents of the input buffer and for you to use the supplementary materials. Here is a different question and answer so that you have something to model your solution on…

   • Question: explain the output of the following code.

     int main() {
         cout << "Type the commented line of code:" << endl;
     /*
     8 eight
     */
         int    i; cin >> i;
         string s; getline(cin, s);
     
         cout << "Line 1: " << i << endl;
         cout << "Line 2: " << s << endl;
     
         return 0;
     }
     

   • Answer…

     After running the code, the console looks as follows…

     Type the commented line of code:
     8 eight
     Line 1: 8
     Line 2:  eight
     

     I'll now explain how the code executes.

     First, "Type the commented line of code:" is printed to the console together with a new line character.

     Next, an int i is declared and we encounter cin >> i, so we follow steps 1-4 of the relevant part of the supplementary materials.

     1. There is nothing in the buffer, so the user is prompted to enter input. After they finish typing…

        BUFFER STATUS: "8 eight\n"

     2. The character '8' is not white space, so we don't have to do anything for step 2.
     3. Similarly, step 3 is complete.
     4. We can interpret the character '8' as the int 8. So 8 is assigned to i and '8' is stripped from the buffer…

        BUFFER STATUS: " eight\n"

     Next, a string s is declared and we encounter getline(cin, s), so we follow steps 1-3 of the relevant part of the supplementary materials.

     1. There is still something in the buffer, so the user is not prompted for more input.
     2. We remove everything in the buffer before '\n' and assign it to s, so " eight" is assigned to s and…

        BUFFER STATUS: "\n"

     3. We remove '\n' from the buffer…

        BUFFER STATUS: ""

     Next, we print "Line 1: 8" with a newline character (since i stores the int 8).

     Finally, we print "Line 2:  eight" with a newline character. That's two spaces between the colon and the 'e'. This is because the string literal had a space at the end and s stores " eight".

3. In Q3, I have provided expectations of what your picture and prose should include. There are 7 bullet points and 6 points allocated to the question. You should therefore expect that a failure to observe one of the bullet points results in at least a one point deduction.

   Regarding the instruction "you can satisfy the last bullet point by labelling your picture with numbers in a different color to your normal writing", here is a video to demonstrate.
