  1. Getting InputsAsking the USER for data Enter username: Velocity (m/s)? : Enter password: Pressure (atm)? : Time till arrival (s)? : Would you like to repeat (y/n)? :

  2. The input() command • NO user-interaction. (HARDCODING) variable = value; • “Prompt the user for data” = “Ask the user for data” • Allow user to enter data with the input() command • When prompting for numerical data: variable = input(‘prompt string’); Or • When prompting for char data: variable = input(‘prompt string’ ,‘s’);

  3. Key Points • Asking the user for data to process is key to any software • In MATLAB, the commandto prompt data is: input() • Two ways of prompting since primarily 2 data-types possible: var = input(‘prompt string: ’); for numerical data var= input(‘prompt string: ’, ‘s’); for char data • Ctrl+C will abort the current run

  4. Try it yourself – cont. • Using the 7 steps, create software for the following problem Pb: Calculate the volume of a hemispherical capsule, knowing the radius and the height of the middle section (see figure). These types of tanks are used in designing tanks for fuel in rockets.

  5. Vocabulary • Hardcoding • Prompt • String (review)
