Answer:

11: Compiler translates a high level source program into a target equivalent (machine language).

An interpreter implements a virtual machine, the high-level programming language of which is the "machine language." The interpreter reads statements more or less one at a time in that language, and executes them as they go along.

12: One could also consider Java either. A compiler (complicated translator) can create code, which is then executed by a complicated virtual machine (interpreter)

13: A preprocessor is an initial translator which removes comments and white space, and group characters together into tokens such as keywords, identifiers, numbers, and symbols, as well as simple syntactic structure analyses. A compiler uses in-depth analysis and nontrivial transformation.

14: C++ implementations based on the early AT&T compiler created an intermediate program in C rather than assembly language

15: Stack-based language, similar to modern Java compiler byte code

16: A method in which a simple interpreter implementation evolves into building more complex versions until the compiler is built.

17: A compiler which translates byte code into machine language immediately prior to each program execution.

18: Lisp and Prolog

19: TEX and TROFF are one of such compilers that translate high-level document descriptions into laser printer or phototypesetter commands. Query language processors for database systems are also compilers that translate languages such as SQL into primitive file operations.

21: without havin to call multiple tools with command-line tools, You can write an entire program in an IDE.

2. In many jurisdictions a small deposit is added to containers to encourage people to recycle them. In one particular jurisdict
RUDIKE [14]

Answer:

Here is the Python program:

small_container = int(input("Enter the number of small containers you recycled?"))

large_container = int(input("Enter the number of large containers you recycled?"))

refund = (small_container * 0.10) + (large_container * 0.25)

print("The total refund for returning the containers is $" + "{0:.2f}".format(float(refund)))

Explanation:

The program first prompts the user to enter the number of small containers. The input value is stored in an integer type variable small_container. The input is basically an integer value.

The program then prompts the user to enter the number of large containers. The input value is stored in an integer type variable large_container. The input is basically an integer value.

refund = (small_container * 0.10) + (large_container * 0.25)  This statement computers the refund that will be recieved for returning the small and larger containers. The small containers holding one litre or less have a $0.10 deposit so the number of small containers is multiplied by 0.10. The large containers holding more than one litre have a $0.25 deposit so the number of large containers is multiplied by 0.25. Now both of these calculated deposits of containers of each side are added to return the refund that will be received for returning these containers. This whole computation is stored in refund variable.

print("The total refund for returning the containers is $" + "{0:.2f}".format(float(refund))) This print statement displays the refund in the format given in the question. The output includes a $ sign and displays exactly two decimal places by using {0:.2f} where .2f means 2 decimal places after the decimal point. Then the output is represented in floating point number using. format(float) is used to specify the output type as float to display a floating point refund value up to 2 decimal places.

Label the strength of a beer based on its ABV. For each beer display the beer's name, ABV, and a textual label describing the st
belka [17]

Answer:

By presuming the question expect us to write a program to address the problem and the solution code written in Python is as follow:

  1. beer_name = input("Enter beer name: ")
  2. abv = int(input("Enter ABV value: "))
  3. if(abv > 10):
  4.    label = "Very High"
  5. elif(abv >=6):
  6.    label = "High"
  7. elif(abv >=3):
  8.    label = "Average"
  9. else:
  10.    label = "Low"
  11. print("Beer Name: " + beer_name)
  12. print("ABV value: " + str(abv))
  13. print(label)

Explanation:

Firstly, we can use input function to prompt user to input beer name and ABV value (Line 1 - 2).

Next, create if else if statements to check abv fallen into which range of value and then set a label accordingly (Line 4 -11). For example if abv is 4, the label will be set to "Average".

At last, print the information of beer that includes beer name, abv value and label (Line 13 - 15).
