Question

1. what is the computational model used in basic programming? (2 pts)

a. concurrent
b. sequential
c. math
d. parallel

1. by tradition, names of variables should be... (2 pts)

a. first letter of each word is capitalized
b. first letter of each word is capitalized except for the first word
c. all upper case
d. all lower case

1. how many bytes does an int variable take up? (2 pts)

a. 2
b. 4
c. 8
d. 16

Explanation:

1. In basic programming, the sequential computational model is common where instructions are executed one - after - another. Concurrent and parallel models involve multiple tasks executing simultaneously or in parallel, and "math" is not a typical computational model for basic programming.
2. By convention in many programming languages, variable names follow a naming convention where the first letter of each word is capitalized except for the first word (camelCase).
3. In most common programming environments and architectures, an int variable typically takes 4 bytes of memory.

Answer:

1. b. sequential
2. b. First letter of each word is capitalized except for the first word
3. b. 4
