Programming WWW problem

1. Construct this series and output the result only: 1/2 + 2/3 + 3/4 + 4/5 + ... + 99/100.

2. Convert the following iterative function into a recursive function and print the result:

int f(int N)

{

int count, sum=0;

for(count = 0; count<=N; count++)

sum = sum + count;

return sum;

}

Note: User should be able to input the value of N. (e.g: for "N==4" the output should be "10". It is a cumulative summation problem)
