Ex 4: write a c++ program that calculate the following series summation:

S= 1+  2/4  + 3/9  + 4/16 +… + 10/100 

int i; double s=0.0;

cout<<"\nThis Program Calculate the the following "

    <<"Series :\nS= 1+ 2/4 + 3/9 + 4/16 + .....+10/100"<

for( i=1;i<=10;i++)

s+=(i/pow(i,2));

cout<<"\nSeries Sum ="<<

cout<<"--------------------------\n"; 

Ex 5: write a c++ program that calculate the following formula:

F= 1/ 1! + 2/2! + 3/3!  + … + 4/4!+ 5/5! 

int n = 0, fact = 1, accuracy = 10;

 double e = 1;

 while ( ++n < accuracy ) {

 fact *= n;

 e += 1.0 / fact;

 }

 cout << "e value is " << e << endl;
