Exercise 1

#rite a pro$ram in C%% &hich carries out follo&in$ tas's

" Create t&o inte$er variables (A and !) and assi$n values to them

" *rint values of both variables on screen

" *rint address of both variables

" Create an inte$er pointer and point it to +rst inte$er variable (A)

" *rint +rst variable (A) value usin$ pointer

" *ointDirect pointer variable to second variable

" *rint the value &here pointer points to

" *rint address and value of pointer

" *ro$ram should not e-it unless user decides to

" Create second pointer and point pointer1 and pointer . to +rst variable

" Create Chan$e value of value of +rst pointer and print value, chan$e value usin$

second pointer and print value of variable

Exercise 3

#rite C%% pro$ram &hich reads a number from user and ma'es use of user de+ned

function &hich accepts an inte$er pointer2 3his function should increment or decrement

sent value by one dependin$ on user choice2 User should pass value by reference to the

function and the option as an ar$ument (1 to increment and . to decrement value)2

*ro$ram should repeat itself &ithout user choice2

Custom function si$nature is4oid IncrementDecrement ( int number, int operation )6

#include

using namespace std;

void IncrementDecrement(int number,int c)

{

if(c==1)

{

number=number+1;

'

if(c==%)

{

number=number1;

'

'

int main() {

int n,c,coice;

cout n;

coutc;

if(c==1)

{

coice=1;

'

if(c==%){

coice=%;

'

-ncrement.ecrement(&n,coice);

cout
