// Line 1 is a variable declaration, creating the count variable with an initial value of 0
// Describe what line 3 is doing, in particular focus on what = is doing

// Answer
// Line 3 is an assignment operation. The = operator assigns the value of the expression on its right
// (count + 1) to the variable on its left (count). This effectively increments the value of count by 1.

// Try breaking down the expression and using documentation to explain what it means
// It will help to think about the order in which expressions are evaluated
// Try logging the value of num and running the program several times to build an idea of what the program is doing
// Answer
// The expression generates a random integer between the minimum and maximum values (inclusive).
// Math.random() generates a random decimal number between 0 (inclusive) and 1 (exclusive).
// Multiplying this by (maximum - minimum + 1) scales it to the range of possible integers.
// Adding minimum shifts the range to start from the minimum value.
// Finally, Math.floor() rounds down to the nearest whole number, ensuring that num is an integer within the specified range.
