In C++  What is the sections doing ? and  What is the output from the sections   below ?  a. int p=o;       for (int i=1; i<=30; i++){       if (i%5==0)        p+=i;           }         cout<<p<<endl;      b.  int count=2;        int g=0;        while (count<=50){        g=count;        cout<<g<<endl;        count +=2;         }         cout<<count<<endl;

a.  typo here:  int p=0;    it is to calculate the sum of all  integers from 1 to 30 which are   divisible by 5.  output is p=105    b.  it is just to display the even integers  from 2 to 50, i.e. 2,4,6,...,50.
