Variables and Constant

Constants and variables are widely used in mathematical equations and expressions. They are also commonly found in the domain of programming, where each language has its own way to differentiate between a constant and a variable. Since they have all sorts of applications, knowing their differences is a good place to start.

Question

1. Write a program that asks the user to enter n and then it computes the value of
the sum:
12 + 22+32 +
+n? = Ei?
...
check" whenn = 200, the answer shou; ld be 2686700
2. The total resistance of n resistors in parallel is:
1
=
R
Suppose we have a network of two resistors with the values 400 Q and 200 . Then our
equation would be:
1
1
1
R 400 * 200
and the total resistance of our two-resistor network is 133.3 Q.
Write a program to compute the total resistance for any number of parallel resistors.
