POINTERS AND CLASSES

1. pointers can be initialized like p = 0 or p = null;

2. when accessing class( struct ) components , using arrow is advisable.

3. The number 0 is the only number that can be directly assigned to a pointer variable

WHAT ARE DYNAMIC VARIABLES??

they are variable created at the time of execution.

the two types of dynamic variables are NEW and DELETE

iii. the new operator has two forms

-& to allocate a single variable
new datatype;


-& to allocate an array of variables

new datatype[intExp];


example :


int *p;
char *q;
int x;

p = &x;// no new memory is allocated
p = new int; //store allocated memory address

 q = new char[16];

OPERATOR DELETE


we use it to avoid memory leak.

[what is memory leak?]

- It is used to destroy dynamic variables so that memory is reallocated again.

single variable;
delete pointerVariable;

an array;

delete [ ] pointerVariable;




delete p;
delete str;

//program to print a string n times without using loop
#include <iostream>
#include <cstdlib>
using namespace std;
void iter(int);



int main() {
int n = 10;


iter(n);
return 0;
}

void iter(int y)
{
string s = "name";
if(y==0)
{
exit;
}
else
{

cout <<s<<endl;
iter(y-1);
}
}

##" Write a definition for a structure type for records consisting of a person’s
wage rate, accrued vacation (which is some whole number of days), and
status (which is either hourly or salaried). Represent the status as one of
the two char values 'H' and 'S'. Call the type EmployeeRecord.

C++ problem@:
An election is contested by five candidates. The candidates are numbered 1 to 5, and the voting is done by marking the candidate number on the ballot paper. Write a program to read the ballots and count the votes cast for each candidate using an array variable count. In case, a number read is outside the range 1 to 5, the ballot should be considered as a “spoiled ballot”, and the program should also count the number of spoiled ballots.
