Amount = P*(1 + R)^N

where R is the interest rate as a decimal number (e.g., 6.5% is 0.065). Write and run a program that performs the following steps:

• Reading the values of P and R from the keyboard.
• Calculating the amount of money that will be available in 5 years.
• Displaying the result.

6. Write and run a program that reads the name, age, sex, height and weight of a student and displays with proper heading for each variable.

7. Write a program to accept a single character from the keyboard. Using cout statement to display the character or keystroke and its decimal, hexadecimal and octal values. Display in the following format:

## Exercise 4

1. Write and run a program that reads a character and writes out a name corresponding to the character:

if the character is ‘F’ or ‘f’ then the name is ‘Frank’

if the character is ‘C’ or ‘c’ then the name is ‘Christine’

if the character is ‘A’ or ‘a’ then the name is ‘Amanda’

if the character is ‘B’ or ‘b’ then the name is ‘Bernard’

otherwise, the name is just the character.

2. Write and run a program that reads an angle (expressed in degrees) and states in which quadrant the given angle lies. An angle A is said to be in the

• first quadrant if it is in the range 0<= A<90
• second quadrant if it is in the range 90<= A<180
• third quadrant if it is in the range 180<= A<270
• and fourth quadrant if it is in the range 270<= A<360.

3. Write and run a program that reads a month from the user and displays the number of days in that month.

4. Write and run a program that reads a numeric grade from a student and displays a corresponding character grade for that numeric grade. The program prints ‘A’ for exam grades greater than or equal to 90, ‘B’ for grades in the range 80 to 89, ‘C’ for grades in the range 70 to 79, ‘D’ for grades in the range 60 to 69 and ‘F’ for all other grades.

5. Write and run a program that reads a marriage code (one character) and writes out a message corresponding to the character:

if the character is ‘M’ or ‘m’ then the message is “Individual is married”

if the character is ‘D’ or ‘d’ then the message is “Individual is divorced”

if the character is ‘W’ or ‘w’ then the message is “Individual is widowed”

otherwise, the message is “An invalid code was entered”.

(Hint: use switch statement).

6. Chapter 4 contains the example program which can solve quadratic equations. Modify that program so that when the discriminant del is negative, the imaginary roots are calculated and displayed. For this case, the two roots of the equation are:

x1 = (-b)/(2a) + sqrt(-del)/(2a)i

x2 = (-b)/(2a) + sqrt(-del)/(2a)i

where i is the imaginary number symbol for the square root of –1. (Hint: Calculate the real and imaginary parts of each root separately).

7. Write and run a program that gives the user only three choices: convert from Fahrenheit to Celsius, convert from Celsius to Fahrenheit, or quit. If the third choice is selected, the program stops. If one of the first two choices is selected, the program should prompt the user for either a Fahrenheit or Celsius temperature, as appropriate, and then compute and display a corresponding temperature. Use the conversion formulas:

what are the products of Nano chemistry?
There are lots of products of nano chemistry... Like nano coatings.....carbon fiber.. And lots of others..
learn
Even nanotechnology is pretty much all about chemistry... Its the chemistry on quantum or atomic level

I only see partial conversation and what's the question here!
what about nanotechnology for water purification
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
Professor
I think

what is the stm
is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
Damian
How we are making nano material?

what is simplest way to understand the applications of nano robots used to detect the cancer affected cell of human body.? How this robot is carried to required site of body cell.? what will be the carrier material and how can be detected that correct delivery of drug is done Rafiq
Rafiq
if virus is killing to make ARTIFICIAL DNA OF GRAPHENE FOR KILLED THE VIRUS .THIS IS OUR ASSUMPTION
Anam
analytical skills graphene is prepared to kill any type viruses .
Anam

why we need to study biomolecules, molecular biology in nanotechnology?
?
Kyle
yes I'm doing my masters in nanotechnology, we are being studying all these domains as well..
why?
what school?
Kyle
biomolecules are e building blocks of every organics and inorganic materials.
