- In C++ Create an array of head pointers, statically allocated of size 101 of that type: Now, create a pointer that can point to the first element: Show how to dynamically allocate an array of 101 elements of head pointers: Write the code to initialize each element to NULL: Rewrite the code to initialize each element to NULL using pointer arithmetic:Specify the problems with the pointer's layout. Although there are exceptions, most computer languages only allow pointers to refer to a single kind of variable.C PROGRAMMING Differentiate the output of the two programs. a. struct node {int x;node *next;};int main(){node *root; // This will be the unchanging first noderoot = new node; // Now root points to a node structroot->next = 0; // The node root points to has its next pointer// set equal to a null pointerroot->x = 5;} // By using the -> operator, you can modify the node// a pointer (root in this case) points to. b.struct node {int x;node *next;};int main(){node *root; // This won't change, or we would lose the list in memorynode *conductor; // This will point to each node as it traverses the listroot = new node; // Sets it to actually point to somethingroot->next = 0; // Otherwise it would not work wellroot->x = 12;conductor = root; // The conductor points to the first nodeif ( conductor != 0 ) {while ( conductor->next != 0)conductor = conductor->next;}conductor->next = new node; // Creates a node at the end of the listconductor = conductor->next; // Points to…
- A pointer int *p is declared, it is able to hold addresses of double type values as well.. Single choice. True FalseThis 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…“Array name can act as a constant pointer”. Justify the given statement by distinguishing array name with pointer variable and suitable examples.Explain in C programming language.
- List 3 properties of a pointerUSING C LANGUAGE COMPLETE THE PROBLEM USING POINTERS AND ARRAYS #include <stdio.h> int main(){} char letters[26]; char *pc1 = letters; /* Equivalent pointer values. */ char *pc2 = &letters; char *pc3 = &letters[0]; letters[4] = "e"; /* Equivalent indexes. */ pc1[4] = ’e’; *(letters + 4) = "e"; *(pc2 + 4) = "e"; pc3 = &letters[10]; /* Equivalent addresses. */ pc3 = &pc1[10]; pc3 = letters + 10; pc3 = pc2 + 10; }What is a variable pointer? What follows? It is a variable array. Why are pointers and dynamic arrays problematic?
- How difficult is it to move shared references into another array while using the C++ programming language? Create a list of potential solutions to the problem. Are shared pointers able to move the objects over which they have control? What gives?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()…When moved swiftly, the pointer submarines.
