cin>>value;
per.setelement(value);
per.getperfect();
per.chksum();
return 0;
}

Search an element in an Array of 20 integer values. (i) Use one Constructor to get input on variable and array. (ii) Use one Constructor to Search the Array. (iii) Use a member function to display the result. (iv) Use Destructor in any suitable position.

#include
using namespace std;
class earray-search
{
public:
int elmt=0,x[20],inp,i;
earray();
~earray();
void proved();
};
earray::earray()
{
cout<<"the elements:"<>x[i];
}
earray::~earray()
{
cout<<"destructing"<>inp;
for(i=0;i<20;i++)
{
if(x[i]==inp)
{
cout<<"found"<<endl;
elmt=1;
break;
}
}
if(elmt==0)
cout<<"Not found"<<endl;
}
int main()
{
search-earray sa;
sa.proved();
}

Write a c++ program to count number of character in a given string

#include<iostream>
#include<string>
using namespace std;

int character (values v)
{
int charnum=v.size();
for(char i=0; i<v.size(); i++)
{
if(v.Location(i)== ' ')
{
charnum--;
}
if(v.Location(i)== '.')
  {
charnum--;
}
}
cout<<"Enter values has "<<charnum <<" Characters:"<<end;
}


int main()

values v;
char i;
cout<<"the type of a values: " ;
cin >> v
getline(v);
character(v);
return 0;
}

Write a c++ program to check whether the given number is odd or even

#include<iostream>
using namespace std;



void Even-Odd(int v)
{
if(v%2==0)
cout<<"the number is Even";
else
cout<<" the number is Odd";
}

int main()
{
int v;
cout<<"the number is check Even or Odd";
cin>>v;
Even-Odd(v);
Return 0;
}

Write a program of function to Sum of all even elements from an Array. The initial value of the array must take from main ( ) as input

#include <iostream>
    using namespace std;

    class evensum
    {
    public:
        void setvalue(int v)
        {
            value =v;
        }
        protected: int value;

    };

class mysum: public evensum
{
public:
    void getsum()
    {
    int temperature,i,a[100],sum=0;
    temperature=value;
    cout<<"Enter "<<temperature<< " values:  ";
    for(i=0;i<temperature; i++)
    {
    cin>>a[i];
    }
    for (i=0;i<temperature;i++)
    {
    if (a[i]%2==0)
    {
    sum+=a[i];
    }
    }
    cout<<"Sum of even values is : "<<sum<<endl;
    }
};
    int  main()
    {
    findsum xy;
    int v;
    cout<<"Enter size of the array: ";
    cin>>v;
    xy.setvalue(v);
    xy.getsum();
    return 0;
    }

Write a program Check whether the given number is palindrome or not. Use individual/separate member function to take input, output and display according to logic. Use Inheritance

#include<iostream>
using namespace std;
class palindrome
{
public:
void setvalue(int v)
{
value=v;
}
protected:
int value;
};
class value:public palindrome
{
public:
int i,t,rev=0;
int devide()
{
t=value;
while(t!=0)
{
i=t%10;
rev=rev*10+i;
t/=10;
}
}

int check()
{
if(value==rev)
cout<<"palindrome";
else
cout<<"not palindrome";
}
};
int main()
{
value v;
int x;
cin>>x;
v.setinput(x);
v.devide();
v.check();
}

Write a program Check Whether the given number is Strange or Not.

#include<iostream>
using namespace std;
int main ()
{
int X,Y,D,prime num=1;
cin>>D;
while(D!=0)
{
X=D/10;
Y=D%10;
cout<<Y<<endl;
D=X;

for(int j=2; j<Y; j++)
{
if(Y%j==0)
{prime num=0;
j=Y;
}
}
}
if(prime num==1) cout<<"stange";
else
cout<<" not stange";
return 0;
}
