1. Pointr Syntax: Basic pointer question SHORT ANSWER ONLY

A. Writ th dclaration of a doubl pointr namd avrag

B. Writ th dclaration of a doubl pointr namd avr and assign nullptr to it

C. Dynamically allocat mmory for a DNA objct and stor its addrss in a variabl namd dnaPtr

D. Dclar a on-dimnsional array of 30 doubls (on th stack) namd rainfall

E. Dclar and allocat mmory (on th hap) for a on-dimnsional array of 256 doubls namd prics

F. Dclar a two-dimnsional array of doubls (on th stack) namd tickrValus with 12 rows and 31 columns

G. Dclar and allocat mmory (on th hap) for a two-dimnsional array of strings namd carMaks with 20 rows, ach with 6 columns

H. Giv th dclaration for a function assignPictur() that taks a pointr to a HugStudntRcord objct

I. Giv th dclaration for a function calculatAvrag() that taks an array of doubls and an int namd count

J.Writ a call to function calculatAvrag(), passing it rainfall

Answers:

A)double *average; //double pointer

B)double *aver=NULL;

C) DNA *object,*dnaPtr;

object = new DNA; // uses default constructor

dnaPtr=&object; //stores DNA object in danPtr variable

D) double rainfall[30]; //allocates memory on stack

E)double *prices;
prices = new double[256]; //allocates memory on heap

F)double tickerValues[12][31]; //allocates memory on stack

G)string *carMakes;
carMakes = new string[20][6]; //allocates memory on heap

I)double calculateAverage(double array[],int count);

J)calculateAverage(a,count);
