C++ Developer - Multi-Dimensional Arrays

The video tutorial covers the concept of multidimensional arrays, focusing on 2D arrays in C programming. It explains how to create, initialize, access, and modify 2D arrays. The tutorial also demonstrates using nested loops to iterate over arrays and includes a challenge to print arrays in reverse order.

What is a common use case for 2D arrays in programming?

• Storing a list of names

• Representing a chess board

• Managing a collection of functions

• Holding a single integer value

How do you declare a 2D array with 2 rows and 3 columns in C?

• int myNums[2][3];

• int myNums[3][2];

• int myNums[3,2];

• int myNums[2,3];

What value is printed when accessing the element at row 0, column 2 in the initialized 2D array?

• 1

• 2

• 4

• 3

What is the correct way to change the value at row 1, column 0 from 4 to 14?

• myNums[0][1] = 14;

• myNums[1][0] = 14;

• myNums[1][1] = 14;

• myNums[0][0] = 14;

What happens if you try to access an index out of bounds in a 2D array?

• The program will ignore the operation

• The program will crash

• The program will print a warning

• The program will access a random memory location

Which loop runs more frequently in a nested loop structure used to iterate over a 2D array?

• The outer loop

• The inner loop

• Both loops run equally

• Neither loop runs

What is the purpose of using nested loops when working with 2D arrays?

• To access and modify elements

• To declare the array

• To initialize the array

• To iterate over rows and columns

Why is it important to use descriptive variable names like 'row' and 'column' in nested loops?

• To make the code run faster

• To avoid syntax errors

• To improve code readability

• To reduce memory usage

What is the result of printing the 2D array in reverse order?

• 123 456

• 321 654

• 456 123

• 6514 321

What is the highest index for a 2D array with dimensions 2x3?

• 3,2

• 2,1

• 1,2

• 2,3
