What is the python code for the function def readFloat(prompt) that displays the prompt string, followed by a space, reads a floating-point number in, and returns it. Here is a typical usage:
salary = readFloat("Please enter your salary:")
percentageRaise = readFloat("What percentage raise would you like?")
assume python does not define count method that can be applied to a string to determine the number of occurances of a character within a string. Implement the function numChars that takes a string and a character as arguments and determined and returns how many occurances of the given character occur withing the given string
Consider the ER diagram of online sales system above. Based on the diagram answer the questions below,
a) Based on the ER Diagram, determine the Foreign Key in the Product Table. Just mention the name of the attribute that could be the Foreign Key.
b) Mention the relationship between the Order and Customer Entities. You can use the following:
1:1, 1:M, M:1, 0:1, 1:0, M:0, 0:M
c) Is there a direct relationship that exists between Store and Customer entities? Answer Yes/No?
d) Which of the 4 Entities mention in the diagram can have a recursive relationship?
e) If a new entity Order_Details is introduced, will it be a strong entity or weak entity? If it is a weak entity, then mention its type?

You can think of a tile as a square on the board on which the game will be played. We will come back to this class later. For the moment you can leave it empty while you work on creating classes that represents characters in the game. • Write an abstract class Fighter which has the following private fields: - A Tile field named position, representing the fighter's position in the game. A double field named health, representing the fighter's health points (HP). An int field named weaponType, representing the type of weapon the fighter is using. This value is used to rank different weapon types: higher values indicate higher weapon ranks. -An int field named attackDamage, representing the fighter's attack power.

Employees work in departments; each department is managed by an employee; a child must be identified uniquely by name when the parent (who is an employee; assume that only one parent works for the company) is known. We are not interested in information about a child once the parent leaves the company. Draw an ER diagram using Crows Foot notation that captures this information.
