C++ Practical Section 10

46. Write a Program for Fibonacci Series.
Answer :

#include<iostream.h>
#include<conio.h>

Void main()
{
int f=0, s=1, t, i, n;
cout<<"Enter n;
cin>>n;

cout<<f<<" "<<s;
for(i=3; i<=n; i++)
{
t=f+s;
cout<<" "<<t;
f=s;
s=t;
}
getch();
}

47.   Write a Program for check that the Number is Prime or not.
Answer :

#include<iostream.h>
#include<conio.h>

Void main()
{
int i, n, prime=1;
cout<<"Enter n";
cin>>n;
for(i=2, i<n; i++)
{
if(n%1 == 0)
{
prime = 0;
break;
}
}
if(prime==1)
{
cout<<#include<iostream.h>
#include<conio.h>

Void main()
{
cout<<"Prime No";
}
else
{
cout<<"Not a Prime No";
}
}

49. Example for Function Template.
Answer :

#include<iostream.h>
#include<conio.h>

template <class T>
Void sum(Ta, Tb)
{
T c;
c=a+b;
return T;
}

Void main()
{
int a=10, b=20;
cout<<"The sum of "<<a<<"and"<<b<<"is"<<sum(a,b);
double x=10.5, y=20.6;
cout<<"The Sum of<<x<<"and"<<y<<"is"<<sum(x,y);
getch();
}

50.   Example of Class Template.

Answer :

#include<iostream.h>

#include<conio.h>

template <class T>

class vector

{

T*V;

int size;

Public:

vector (int m);

vector (T*a);

T operator *(vector &y);

};

template <class T>

vector<T> :: vector (int m)

{

v = new T[size = m];

for(int i=0; i<size; i++)

v[i]=0;

}

template <class T>

vector <T> :: vector (T*a)

{

for(int i=0; i<size; i++)

v[i] = a[i];

}

template <class T>

Tvector <T> :: operator*(vector &y)

{

T sum=0;

for(int i=0;i<size;i++)

sum+=this -> v[i] * y.v[i];

return sum;

}

Void main()

{

vector <int> T,(5);

T1 = {10,20,30,40,50};

vector <int> T2()5;

T2 = {80,90,60,70,15};

vector <int> T3 = T1 * T2;

for(int i=0; i<5; i++)

cout<<T3[i];

getch();

}
