Assignment 1
Write a program to calculate the current equation

L  1 2  
p  2   1  sin   
 4           
g          2 
Where p is the period of pendulum in seconds,
g=980 cm/sec2 (acceleration), L is the
pendulum length in cm,  is the angle of
displacement in degrees.
Assignment 2
Suppose that the gas company bases its charges
on consumption according to the following
table:

Gas Used                   Rate
First 70 cubic meters    \$5.00 minimum cost
Next 100 cubic meters   5 .0 ¢ per cubic meter
Next 230 cubic meters   2.5 ¢ per cubic meter
Above 400 cubic meters   1.5 ¢ per cubic meter
Continue of assignment 2
Meter readings are four-digit numbers that
represent cubic meters. Write a program in
which the meter reading for the previous
month and the current meter reading are
entered and then the amount of the bill is
calculated. The current reading may be less
than the previous one; for example the
previous reading may have been 9897, and
the current one is 0103. Use IF statement.
Assignment 3
Write a program to read a set of numbers, and
calculate the mean, variance, and standard
deviation of the set of numbers. The mean and
variance  of numbers x1, x2, …, xn can be
calculated using the following formulas:
2
1    n
1    n
1       
n
mean  x   xi           xi  2   xi 
2

n i 1          n i 1   n  i 1 
The standard deviation is the square root of the
variance.
Assignment 4
Write a program to read a collection n of sets k of
positive numbers, and calculate the mean,
variance, and standard deviation for each set k of
numbers. Write i for 1,..,i,..n and the
corresponding calculated values in a file. The
mean and variance of numbers x1, x2, …, xk can
be calculated using the following formulas:
2
1  k
1  k
1  k

mean  x   xi           xi  2   xi 
2

k i 1          k i 1    k  i 1 
The standard deviation is the square root of the
variance.
Assignment 5

Write a program that includes a function that
calculates the equation F= xn sin x. Write the
values n, x, and F on the screen and in a file
‘data_f.data’. Repeat the program for positive n.
Assignment 6
Write a program that uses a module that calculates
the equation:
n
x sin x
F
n
Both denominator and nominator are calculated by
two different functions. Write the values n, x, and
F on the screen and in a file ‘data_f’. Repeat the
program for positive n.
Assignment 7

Write a program that reads the diameters and
heights of several right circular cylinder and
displays the circumference, total surface area
(including the ends), and the volume of each.
Circumference (C)= 2  r ; where r is the radius
Total surface area = C (h+r); where h is the height
Volume =  r2 h. Use one subprogram to calculate
above equations.
Assignment 8

Write a function that accepts an integer N and
returns an array containing the first N
square root of

1, 2 , 3 , ...., N

Repeat the program for positive N.
Assignment 9
Write a program to read an array of numbers from
the user, and use one subprogram to calculate the
mean, variance, and standard deviation of the set
of numbers. Use query control method to repeat
the program. The mean and variance  of
numbers x1, x2, …, xn can be calculated using
the following formulas:
1 k
mean  x   x j
k j 1
1 k
   xj  x
k j 1
         2

The standard deviation is the square root of the
variance.
