- This is my c++ homework, and I get a question about the following code written by the professor. I did not understand the "p++" in the code, and I do not understand why we have to write this. I think we can just simply assign *pn=n then will be okay? why we write p++? Please explain to me, thank you. // more pointers #include <iostream> using namespace std; int main () { int numbers[5]; int * p; p = numbers; *p = 10; p++; *p = 20; p = &numbers[2]; *p = 30; p = numbers + 3; *p = 40; p = numbers; *(p+4) = 50; for (int n=0; n<5; n++) cout << numbers[n] << ", "; return 0; }What is the correct way to assign the pointer p to the address of x?. Single choice. p = %x; p = &x; &p = *x; *p = &x;i want to swap the value of 5.34 to 2.0 in the latter part what should I do? thank you in advance for your idea and help #include <stdio.h>#include <stdlib.h> int main()//MAIN{ char c_1920213 = 'A'; char *pcc_1920213 = &c_1920213; /* pc points to c*/ double dc_1920213 = 5.34; double *pd1c_1920213, *pd2c_1920213; printf("VALUE OF C BEFORE POINTER: %c", *pcc_1920213); *pcc_1920213 = 'B'; /* Dereferenced pointer: c is now equal to 'B'. */ printf("\nVALUE OF C AFTER POINTER: %c \n", *pcc_1920213); pd1c_1920213= &dc_1920213; /* pd1 points to d */ printf("VALUE OF pd1 BEFORE POINTER: %lf ", *pd1c_1920213); pd2c_1920213= pd1c_1920213; /*pd2 and pd1 now both point to d */ printf(" \nVALUE OF pd1 AFTER POINTER: %lf ", *pd1c_1920213); *pd1c_1920213 = *pd2c_1920213 *2.0; /* equivalent to d = d * 2.0; */ }
- Problem 8. What is the correct syntax of declaring array of pointers of integers of size 10 in C++? a) int arr = new int[10]; b) int **arr = new int*[10]; c) int *arr = new int[10]; d) int *arr = new int*[10];Using Dr-Racket, what is the purpose of the number function?(define (number n)(local [(define (abstract int)(* int 11))] (build-list n abstract))) A) Create a list of the first n multiples of 11 starting at 11.

- C++ Explain your answer. True or False? After the following lines of code are executed, the pointer John is pointing to null. Person* John = new Person(); delete John;please give implementation of void write(u_int32_t address, u_int32_t data){///// REPLACE THIS /////read_fifo(address);return;}In C, write a function that gets 3 pointers int* a, int* b, int* c, and rotates the values in their addresses to the left. That is, a gets the value of b, b gets the value of c, and c gets the value of a. void rotate3 (int* a, int* b, int* c); For example, if we have int x=1, y=2, z=3, then after calling rotate3 (&x, &y, &z) we should have x==2, y==3, and z==1. if we have int x=7, y=1, z=6, then after calling rotate3 (&x, &y, &z) we should have x==1, y==6, and z==7.
