One Minute Evaluations for 9-11 September

CS 305 - Computer Algorithms I

• Topic: Type of data starting from bit, int float; atomic [?]; composite arrays.

• Topic: We talked about the different data types and their quirks and advantage of each.

  Question: How can you implement a dynamic data type array?

  One minute response: We'll cover this in detail in the next section, but essentially you allocate larger or smaller vectors as you need them, and copy the existing data to the new vector each time, deallocating the old vector when done.

• Topic: We talked about simple data structures and uses for them.

  Question: Why use multidimensional arrays?

  One minute response: Sometimes it's a useful way to organize data. For example, you can consider a year to be a 4-dimensional vector: a year is a vector of 12 months; a month is a vector of 4 weeks, a week is a vector of 7 days; and a day is a vector of 24 hours.

• Topic: Data types.

  Question: What is the difference between signed and unsigned?

  One minute response: Integers I'm guessing you're asking about. Unsigned integers can only represent non-negative numbers.

• Topic: Signed and unsigned integers, chars [?] [?] notation.

  Question: How do vectors deviate from the [?].

• Topic: Data types.

• Topic: We talked about data structures.

  Question: What's an integer?

• Topic: We talked about data types; all the characteristics of them and about array and their properties and how and when to use them.

• Topic: We talked about data types and signed vs. unsigned data. We also covered assignment turn-in and how to ask good questions.

  Question: How and in what way are signed and unsigned data implemented?

  One minute response: The only way signed and unsigned data differ is in the way they're handled in the CPU, which is determined by the code; otherwise, signed and unsigned data are identical.

• Topic: We talked about basic and composite data types.

  Question: I would like a more clear answer about unsigned integers because listening and reading the book has left me with a very general definition.

  One minute response: O.k., but what's the question to which you want an answer?

• Topic: We talked about nature of data types, covering both the definitions and properties of simple and complex data types.

  Question: argv is a vector, but not the same type you told us about. What is it?

  One minute response: It's a matrix (that is a 2-dimensional array) but instead of each element of argv being another vector, it's a pointer to a vector. This arrangement is useful for argv because it allows having rows of different sizes without wasting space.

• Topic: Data types.

  Question: What is the difference between one dimension and a plain array.

  One minute response: There is no clear difference; the terminology varies widely. I consider the unadorned term "array" to mean an array of arbitrary dimensions, while a vector is a 1-dimensional array.

• Topic: Data structures, atomic, compound, overloaded function, questions and assumptions.

  Question: No more questions at this time.

• Topic: Basic data types and composite data types.

• Topic: Arrays and integers, floating point, chars, loops, overflow.

• Topic: Data structures, atomic and composite.

  Question: Are regular ints signed or unsigned?

  One minute response: Without designation, ints are signed.

• Topic: Arrays and data structures.

• Topic: Languages defined, data types, arrays.

• Topic: Array and multidimensional arrays, data types, their relations, etc.

• Topic: We talked about design and data types.

• Topic: We talked about data types.

  Question: I'd like to see more about signed usage.

  One minute response: Signed usage is the default, so you've been using all along. About what in particular did you want to see more of?
