ruslelena [56]

Answer:

def calcSum(d):
sum = 0
for x in d:
sum += int(x)
return sum
digits = input("Please enter your digits: ")
print(calcSum(digits))

Explanation:

The solution code is written in Python.

Firstly, create a function that take one input digit string (Line 1).

In the function, create a sum variable with initial value 0.

Use a for loop to traverse through each character in the digit string and in the loop use int method to convert each character to integer and add it to sum variable (Line 3-5) and return the sum as output.

Next, use input function to prompt user enter a digit string (Line 7).

Lastly test the function by passing the input digit as argument and print the result (Line 8).

Brian gathers data from his classmates about the computers they own such as the type of operating system, the amount of memory,

Stells [14]

Incomplete question. The Options read;

A. The year purchased

B. Brian's classmates

C. The amount of memory

D. The type of operating system

Answer:

B. Brian's classmates

Explanation:

Remember, the question is concerned about "the individuals" in the data set, so the year they purchased their computer, neither is the amount of memory of the computer and the type of operating system can be classified as individuals in the data set.

Hence, we can correctly say, only Brian's classmates are the individuals in this data set.

Assume that you have an ArrayList variable named a containing 4 elements, and an object named element that is the correct type t

jonny [76]

Answer:

Option (4) is the correct answer.

Explanation:

In Java programming language ,array collection starts from 0 index location and ends in a size-1 index location. So to access the last elements the user needs to use a[Size-1] statement. so to modify the value of the last location of the array the user needs to use "a[size-1]= element;".

But when the user wants to add some new value to the end of the array list collection then he needs to use the statement--

a.add(element); //where add is a function, element is a value and a is a array list object.

Another option is invalid because--

Option 1 is not the correct because "a[3]=element;" modify the value of the 3rd element of the array.
Option 2 gives a compile-time error because add functions bracts are not closed.
Option 3 gives the error because a[4] gives the location of the 5th element of the array but the above question says that a is defined with 4 elements.
