KonstantinChe [14]

Answer:

Follows are the code to this question:

n= int(input("please enter number of bits, which want to convert for binary to decimal numbers: "))

p= 1#defining variable p for calculate power

d= 0#defining variable d for calculate decimal value

for i in range(n):#defining for loop for input bits value

   b= int(input("Enter the bit value from lowest to highest: "))#input value in b

   if b==1:#defining if block that check input is 1 value

       d=d+p#calculating decimal value

   p=p* 2#calculating power

print("The converted decimal number is:",d)#print value

Output:

please find the attached file.

Explanation:

In the above-given code, n variable is defined, which takes the number of bits value which you want to convert into a decimal value.

In the next step, "d and p" variable is defined that calculates the power and decimal number and store its value respectively, in this step, a for loop is used that uses the "b" variable for inputs bits value into lowest to the highest form, and use the if block.

In this block, it checks if the input value is one then it calculates its power and store its value into the "d" variable and use the print method to print its value.

What is one advantage of top-down programming design?
mojhsa [17]

Answer:

Programmers can take advantage of abstraction to focus on specific tasks.

Explanation:

When we excel in some subjects, we can do abstraction in that subject. Abstraction means you understand by the term, and you do not need details of that term. Like you say some tasks will be done by a graphic designer as a project manager, and you do not need to understand at that point what he will be doing, and that is because you can write in a word or few what is going to be the outcome. And hence, the programmers can take advantage of abstraction to focus on specific tasks. And this is the correct option.
