Chapter 12, Problem 15SA
Explanation of Solution
The problem with the program has been explained in the in-lined comments:
#include <iostream>
using namespace std;
int main()
{
//pointer variables declared and memory allocated
double *firstPtr = new double; //Line 1
double *nextPtr = new double; //Line 2
//value assigned to pointer variable
*firstPtr = 62; //Line 3
//nextPtr is assigned the pointer firstPtr
//so nextPtr points to a memory location
//having a stored value of 62
nextPtr = firstPtr; //Line 4
//memory pointed to by both the pointers are
//deallocated
delete firstPtr; //Line 5
delete nextPtr; //Line 6
//fresh memory i...

- Instructions: In the code editor, you are provided with the definition of a struct Person. This struct needs an integer value for its age and a character value for its gender. Furthermore, you are provided with a displayPerson() function which accepts a struct Person as its parameter. In the main(), there are two Persons already created: one Male Person and one Female Person. Your task is to first ask the user for the age of the Male Person and the age of the Female Person. Then, define and declare a function called createKidPerson() which has the following definition: Return type - Person Name - createKidPerson Parameters Person father - the father of the kid to be created Person mother - the mother of the kid to be created Description - creates a new Person and returns this. The age of this Person will be set to 1 while its gender will be set based on the rules mentioned above.

- A prime number is an integer value that is only divisible by 1 and itself. 2, 3, 5, 7, and 11 are examples of prime numbers. You have been provided with two function definitions: The is_prime () function takes an integer parameter number, and returns True if number is prime and False otherwise. The get_next_prime () function also takes a single integer parameter number, and returns the first prime number larger than it. You must not change the implementation of these 2 functions. Complete the get_primes_list() function that takes a single list of integers called numbers as parameter. You can assume that the integer items in this list will be non-negative. The function must update this list so that items that are not prime numbers are updated to the first prime number larger than them. To implement this function you must call both the is_prime () and get_next_prime () functions. Some examples of the function being called are shown below. Note: the get_primes_list() function does not…arrow_forwardASAParrow_forwardRUBYarrow_forward
