IGME 105 Written Exam 2 Questions and
Answers 100% Solved
How to use Array variables Correct Answ_1. Declare the variable
2. Initialize it
3. Access its value
What number does the array indices starts Correct Answ_0
How to determine the length of an array Correct Answ_Use the Length property of an array
to determine its size.arrayIdentifier.Length
How array elements are stored in memory? Correct Answ_Array elements are stored in
contiguous memory, one right after another.
what is the formula to calculate the memory address of an array element, given the element's
index, the array's base memory address and the size of each element? Correct
Answ_elementAddress = arrayAddress + index * size
, What's a method? Correct Answ_Defines the behavior specific to a class

reusability
How modularity works Correct Answ_Break down code into smaller, related parts
More manageable and readable
