Week 1 - C

Question 1

What qualities should we look out for in our code to make sure they are well designed?

Answer 1

1. Correctness - if our code works correctly and how as intended
2. Design - Based on how efficient and how easily readable it is
3. Style - how aesthetically formatted our code is, in terms of consistent indentation and other placement of symbols.

Question 2

What are the two kind of outputs functions can have?

Answer 2

1. side effects - such as something printed on a screen
2. return values - a value that is passed back to our program that we can use or store for later.

Question 3

What is truncation and how can we prevent it?

Answer 3

Truncation is when precision after the decimal point is lost when using mathematical operators on numbers.

We can cast (or convert) our data type to another data type

Ex. float z = (float) x / (float) y;

the ‘(float)’ converts the integer into a floating point value
