Given variables category, heat, and voltage, declare and assign the following pointers: • character pointer categoryPointer is assigned with the address of category. • integer pointer heatPointer is assigned with the address of heat. • double pointer voltagePointer is assigned with the address of voltage. Ex: If the input is V 150 5.5, then the output is: Product category: V Operational limit: 150 degrees at 5.5 volts. 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20} char category; int heat; double voltage; *Your code goes here */ cin >> category; cin >> heat; cin >> voltage; cout << "Product category: " << *categoryPointer << endl; cout << "Operational limit: << *heatPointer << return 0; degrees at " << fixed << setprecision (1) << *vol

This lab will exercise your understanding of some of the concepts covered in Chapter 14: pointers and linked lists 1. Declare an integer pointer variable intPointer. Initialize it to point to an int variable named someInt. Assign the value 451 to someInt and output (cout) the variable someInt and output (cout) the value pointed to by intPointer. Write an assignment statement that indirectly stores 900 into the value pointed to by intPointer. Output (cout) the value pointed to by intPointer and output (cout) the variable someInt, 2. Declare a pointer variable charArrPointer and initialize it to point to the first element of a three-element char array named initials. Write assignment statements to store 'A', 'E', and 'W' into the first three elements of the array POINTED to by charArrPointer. Do NOT store any values directly into the array named initials. 3. Output (cout) the data in array charArrPointer and the data in array initials. 4. Copy the following code into your program above…
What is a variable pointer? What follows? It is a variable array. Why are pointers and dynamic arrays problematic?
Given variables category, heat, and voltage, declare and assign the following pointers: character pointer categoryPointer is assigned with the address of category. integer pointer heatPointer is assigned with the address of heat. double pointer voltagePointer is assigned with the address of voltage. Ex: If the input is C 355 3.5, then the output is: Product category: COperational limit: 355 degrees at 3.5 volts. #include <iostream>#include <iomanip>using namespace std; int main() { char category; int heat; double voltage; /* Your code goes here */ cin >> category; cin >> heat; cin >> voltage; cout << "Product category: " << *categoryPointer << endl; cout << "Operational limit: " << *heatPointer << " degrees at " << fixed << setprecision(1) << *voltagePointer << " volts." << endl; return 0;}
1: This program demonstrates the use of pointers. What is the output of this program? Assume we know that the initial address of x is 0012FF44. #include <iostream> using namespace std; int main() { int x=25; int *ptr; // pointer ptr=&x; cout<<x<<endl; cout<<*ptr<<endl; cout<<ptr<<endl; //Now we assign 100 to x *ptr=100; cout<<endl; cout<<"Now we assign 100 to x:"<<endl; cout<<x<<endl; cout<<*ptr<<endl; cout<<ptr<<endl; return 0; } Write down the output:

C++ Pointers must be used to solve the following problem. Write a function createPassword() with no return value to randomly select 8 capital letters from the alphabet. The function receives the address of the first characters of the password string as parameter. Hint: Declare a characters string that contains all the capital letters of the alphabet and use the index values of the characters in the string for random selection of characters, e.g.char alpha [27] = “ABCDEFGHIJKLMNOPQRSTUVWXYZ”;char *pAlpha = alpha; Display the password from the main() function. Write a function replaceVowels() with no return value to replace all the vowels (A, E, I, O, U) that have been selected with a symbol from the list ($ % @ # &). That is, A must be replaced by $, E replaced by %, I mustbe replaced by @, O replaced by #, and U must be replaced by &. The function receives the address of the first characters of the password string as parameter. Display the password agin from the main()…
1. Write a function called void swap with two parameters, which will receive the addressof x and y as pointer. The function should swap the value of x and y only if x is larger thany. Print the value of x and y after the function call. 2. Write a function called double getAverage(int *array, int SIZE), whereit accept the array as pointer, and return the average of the array. Print the returnedvalue from this function. Always use *array rather than subscript to access the arrayvalue.
std::shared_ptr is a class that implements the concept of _____. Select one: a. shared ownership of the pointer it contains b. exclusive ownership of the pointer it contains c. no ownership of the pointer it contains d. partial ownership of the pointer it contains
