What is the data type of pointer variables? Suppose that we don‘t know the name of a variable but we do know its address. Can we access the contents of that variable? Explain briefly.
Subject: C++
Please solve and show steps, work, and information related to this problem. Thank you.
The following C++ code performs a set of various arithmetic operations using both pointers and references:
Fill in a memory table that shows the final values for both function a and function b.
Indicate the final values of each parameter, passed in variable(s), and the return value of the function. Provide a separate copy of this memory table for each function.
- in this exercise, please do not include and use string class. The function is using only array notation and manipulation.- string functions such as strlen is not allowed.- it should not have multiple return statements in the same function- there should be no global variable.- the function should not traverse the arrays more than once (e.g. looping through the array once only)
A C++ PROGRAM named "changeCase" that takes an array of characters terminating by NULL character (C-string) and a boolean flag of toUpper. If the toUpper flag is true, it will go through the array and convert all lowercase characters to uppercase. Otherwise, it will convert all uppercase to lowercase.
For example, if the array is {'H', 'e', 'l', 'l', 'o', '\0'} and the flag is true, then the array will become{'H', 'E', 'L', 'L', 'O', '\0'}. And if the flag is false, the array will become{'h', 'e', 'l', 'l', 'o', '\0'}

- Write a program in C++ of how to use two-dimensional dynamic arrays. Follow the instruction below; - Declare the function of fill and print - Create main function and include your information details - Declares 'board' to be a pointer to a pointer of type int - Declare the 'rows' and 'columns' as integer variables - Prompt user to enter the number of rows and colums - Get the user input of rows and colums - Create the rows of board - Create the columns of board - Insert elements into board - Print the elements of boardarrow_forwardConsider the following C++ Code - Write a C++ code that outputs the contents of the array to which strPtr Points and deallocates the memory space occupied by the array to which strPtr points. - Can you modify the code to use a different array size for strPtr? How would this affect the output of the program?arrow_forwardIn Assembly 1. Write code that traverses (or goes through) the following array using the ESI register: .dataarrayOfWords 1020h, 3040h, 5060h, 7080h, 9090h 2. Write code that again, traverses the array in Question #1, but this time using a loop. 3. Using the same array in Question #1, access the 3rd element in the array (the one with subscript 2)4.

Kindly use only SELECTION, ITERATION, INPUT, AND OUTPUT, FUNCTION, ARRAY, AND STRING ONLY.arrow_forward- in this exercise, please do not include and use string class. The function is using only array notation and manipulation.- string functions such as strlen is not allowed.- it should not have multiple return statements in the same function- there should be no global variable.- the function should not traverse the arrays more than once (e.g. looping through the array once only) write a c++ program named "isTheLastNumberTheMax" that accepts an array of integers and its size. It will return true if the last number in the array is the maximum number in that array and false otherwise. In addition, it also returns another boolean to indicate whether this list contains more than one maximum value.For example, if this is called with the array of {10, 20, 30, 40, 50}, it will return true and falseIf this is called with the array of {50, 10, 20, 30, 40, 50}, it will return true and true.arrow_forward
