Class Implementation and Vector Loops
Part A

Implement all member functions of the following class:

class Person

{

public:

Person();

Person(string pname, int page);

string get_name() const;

int get_age() const;

void set_name(string pname);

void set_age(int page);

private:

string name;

int age; //0 if unknown

};

Part B

Write a loop that fills a vector V with ten random numbers between 1 and 100.

Part C

Write a loop that fills a vector V with ten different random numbers between 1 and 100.

Solution

#include <iostream>
#include <vector>
#include <time.h>
#include <stdlib.h>
#include <algorithm>

using namespace std;

//PART A
class Person
{
public:
Person();
Person(string pname, int page);
string get_name() const;
int get_age() const;
void set_name(string pname);
void set_age(int page);
private:
string name;
int age; //0 if unknown
};

Person::Person()
{
age = 0;
name = \"\";
}

Person::Person(string pname, int page)
{
name = pname;
age = page;
}

string Person::get_name() const
{
return name;
}

int Person::get_age() const
{
return age;
}

void Person::set_name(string pname)
{
name = pname;
}

void Person::set_age(int page)
{
age = page;
}

void printVector(vector<int> V)
{
vector<int>::iterator it;
for(it=V.begin() ; it < V.end(); it++)
cout<<*it<<\" \";

cout<<endl;
}

int main()
{
srand(time(NULL));

int len_vector = 10; //length of the vector
int RAND_RANGE = 100;
int i, r;

vector<int> V;
//PART B

for(i=0;i<len_vector;i++)
{
r = rand()%RAND_RANGE+1;
V.push_back(r);
}

printVector(V);
V.clear();

//PART C
for(i=0;i<len_vector;i++)
{
r = rand()%RAND_RANGE+1;
if ( find(V.begin(), V.end(), r) == V.end() )
V.push_back(r);
else
i--;

}

printVector(V);

return 1;
}
