If Scheme were a pure functional language, could it include DISPLAY ? Why or why not?​
VARVARA [1.3K]

Answer:

When Scheme is a pure functional language, it cannot include the function DISPLAY. Since the pure functional languages will return the same value whenever the same expression is evaluated, and the DISPLAY would be the output and thus it cannot be part of the purely functional language. Thus in the pure functional language we can evaluate the expressions with the same arguments and it returns the same value since there is no state to change.

Assume that a file containing a series of integers is named numbers.txt. Write a program that calculates the average of all the
Anna [14]

Answer:

Program in Python:

file = open("numbers.txt", "r")

count = 0

isum = 0

content = file.readlines()

for nums in content:

    num = nums.rstrip('\n').split(" ")

         for i in num:

              isum= isum + int(i)

              count = count + 1

print("Average: "+str(isum/count))

Explanation:

This line opens the file named numbers.txt

file = open("numbers.txt", "r")

This line initializes num to 0

count = 0

This line initializes sum to 0

isum = 0

This line reads the content of the opened file file

content = file.readlines()

This iterates through the content of the file

for nums in content:

This removes trailing new lines and blank spaces from each number

    num = nums.rstrip('\n').split(" ")

This also iterates through the content of the file

         for i in num:

This calculates the sum of the numbers in the file

              isum= isum + int(i)

This counts the numbers in the file

              count = count + 1

This calculates and prints the average of the numbers

print("Average: "+str(isum/count))
