  1. [10 pts] Read today's lecture notes. Honestly declare how you read the notes.
    1. (10 pts) I read the notes carefully. I have a good understanding of the topics therein.
    2. (10 pts) I read the notes carefully, but I don't really understand the following points well:
    3. (0 pts) I didn't read the notes carefully.
  2. [10pts] For each of the below, circle whether it is an expression, statement or neither.
    expression / statement / neither 
    double x;
    expression / statement / neither 
    3 / x
    expression / statement / neither 
    y = x*5
    expression / statement / neither 
    4 + x /
    expression / statement / neither 
    x = 4;
  3. [18pts] Assume the following declarations. Fill in the table with the type and values for the given expressions.
    double a;
int b;
char c;
a = 16.4;
b = 3;
c = 4*a + b;
    		 
    expressiontypevalue
    a + b
    'a'+ b
    'b'-'a'
    a / 4
    b / 4
    b % 4
    c
    int(c)
    b = a
  4. [4pts] What is the output of the following code? 
    
cout << (2.5*4)/5 << endl << 2.5*(4/5) << endl;
  5. [4pts] With super vision you look into your computer and see that a particular byte in memory has contents 00101010.
    • If we interpret that byte as a char, what character does it represent?
    • If we interpret that byte as a bool, what value does it represent?
  6. [54pts] Write a program hw.cpp that reads in a 3-letter word in uppercase letters and prints out the same word with lowercase letters. A typical run of the program should look like this (user input colored red): 
    Input a 3-letter word in uppercase letters: CAT
Output: cat
    Hint: look at the ASCII table and think about how to go from the ASCII value of a uppercase letter to the ASCII value of the same letter in lowercase.
