Question

which data type should be used for a variable that will store the user's year of birth

Answer 1

To store a user's year of birth, the most appropriate data type would typically be an **integer**. This is because a year is represented as a whole number (e.g., 1980, 1995, 2001). Thus, using an integer allows for straightforward comparisons and calculations, such as determining someone's age.

For example, in many programming languages you would declare the variable as follows:

- In Python: `year_of_birth = 1990`
- In Java: `int yearOfBirth = 1990;`
- In JavaScript: `let yearOfBirth = 1990;`

Using an integer is optimal because years do not require decimal points or other complex representations.

Answer 2

a stack overflow occurs when:
A. too much data is put in a heap
B. too many heaps are put in a stack.
C. too many stacks are put in a heap
D. too much data is put in a stack

Answer 3

A stack overflow occurs when:

**D. too much data is put in a stack.**

This happens when the program uses more stack space than is allocated, typically due to excessive function calls or large local variables in recursive functions. Once the limit is exceeded, a stack overflow error occurs, leading to a crash or an exception depending on the programming language.
