- What is a multidimensional array, and how does it work?What are the major benefits of using arrays? How many dimensions can an array contain in total? To put it another way, what's the difference between an unstructured variable type and one? Give an example of a data structure with a lot of facets.What are the principle advantages of arrays? How many dimensions can an array have? How does a structure differ from a primitive variable type? Give an example of a complex data structure?
- Which advantages do arrays offer? There is a limit on the number of dimensions that an array can have. In what ways are variables unique across data structures? Can you provide me an instance of a more complex data structure?What advantages do arrays have? There is a limit on the total number of dimensions that an array can have. What makes variables special in comparison to other data structures? Can you provide me an instance of a more complex data structure?How can one simply copy a collection of shared pointers into another array using the C++ programming language? Create a list of potential answers to the problems you've been presented with in this scenario. Is it true that when shared pointers are copied, the objects they control are likewise copied along with them? Explain
- What are some common algorithms used for sorting data in computer science, and how do they compare in terms of time complexity, space complexity, and best-case and worst-case performance for different types of input data?Vectors store a linear arrangement of values, accessed by a single index. Two-dimensional arrays store a tabular arrangement of values, accessed by two indexes, for example matrix[i][j], where i is the row index, and j is the column index. A common two-dimensional array that you should have seen early on in your education is a multiplication table. For example, here is the multiplication table up to 5 x 5: 1 2 3 4 5 1 1 2 3 4 5 2 2 4 6 8 10 3 3 6 9 12 15 4 4 8 12 16 20 5 5 10 15 20 25 Write a program that asks the user for the number of rows and columns for a multiplication table and prints out the corresponding results.Given a two dimensional array, with 20 rows and 30 columns, allocated in ANNA-- List[20][30]. Assume row-major ordering is used to store the array in memory and the address of the first array element (List[0][0]) is 0x1234. Assuming each array element occupies one word, what would be the memory address of the element List[10][21]. (Express the address in Hexadecimal.) Refer to slides 84, 85 inLecture4.pdf (“Multidimensional Array Addresses”). Answer: Address = Starting address + [(row_num)*NUM_OF_COLUMNS + col_num]*Element_Size= 0x1234 + [10*30 + 21]*1 = 4660 + 321 = 4981 = 0x1375 I am not understanding how 4660 is calculated and the final answer
