Data Structures Midterm Exam WRI

Is ultimately stored in computers as patterns of bits, though these days most programming languages deal with higher-level objects, such as characters, integers, and floating-point numbers.

• Array

• Data

• Array items

Is a collection of similar types of data.

• Array

• Data

• Array items

Typically stored in a sequence of computer memory locations, but to discuss them, we need a convenient way to write them down on paper.

• Array

• Data

• Array items

Is a condition that does not change during the execution of a given program or algorithm.

• Loop

• Invariants

• Index

Arrays work on an _________ system starting from 0 to (n-1), where n is the size of the array.

• Index

• array

• address

Arrays are typically defined with square brackets with the size of the arrays as its argument.

• Curly brace

• Brackets

• Parenthesis

This is a Boolean expression calculated at the beginning of each iteration to determine whether the loop body will execute or stop.

• Loop body

• Loop update

• Loop condition

• Loop initialization

We initialize loop variables before starting the first iteration of the loop.

• Loop body

• Loop update

• Loop condition

• Loop initialization

We perform increment/decrement operations on loop variables to control repetitions of the loop.

• Loop body

• Loop update

• Loop condition

• Loop initialization

The core part of a loop where we perform required operations to manipulate data at each iteration.

• Loop body

• Loop update

• Loop condition
