Answer:
D) A comment line begins with #
Explanation:
Comments are used in programming to explain what a line or block of code is doing.
It helps the programmer easily remember what their code was about when they come back to it having left it for a while.
Also comments help other programmers understand code written by one programmer.
A comment or an in-line comment usually begins with #. That way the computer skips it and doesn't regard it as a line of code.
Answer: D. A comment line begins with #.
Explanation:
In the text, it stated, "The easiest way to add a comment is to start the line with the pound sign (#)."
(Comments are notes that allow you to write anything without affecting the code itself. Comments can be utilized to indicate when and how you later changed a program, and provide a description of the changes.)
I hope this helped!

Answer:
soft skill
Explanation:
If an app asks for a user's age, it may be because the app requires a user to be over a certain age to use some of the services it provides. Write a function called checkAge that takes one parameter of type String. The function should try to convert this parameter into an Int value and then check if the user is over 18 years old. If he/she is old enough, print "Welcome!", otherwise print "Sorry, but you aren't old enough to use our app." If the String parameter cannot be converted into an Int value, print "Sorry, something went wrong. Can you please re-enter your age?" Call the function and pass in userInputAge below as the single parameter. Then call the function and pass in a string that can be converted to an integer.
Go back and update your function to return the age as an integer. Will your function always return a value? Make sure your return type accurately reflects this. Call the function and print the return value.
func checkage(age: String)->Int?
{
if let age_type = Int(age)
{
if age_type > 18 {
return "Welcome!"
}
else if age_type < 18 {
return"Sorry, but you aren't old enough to use our app."
}
}
else {
return "Sorry, something went wrong. Can you please re-enter your age?"
}
return age_type
}
Answer and Explanation:
Here the programming language swift is being used. There is a slight error in the program shown above:
var userInputAge=9
func checkage(age: String)->int?
{
if let age_type = Int(age)
{
if age_type > 18 {
return "Welcome!"
}
else if age_type < 18 {
return"Sorry, but you aren't old enough to use our app."
}
}
else {
return "Sorry, something went wrong. Can you please re-enter your age?"
}
return age_type
}
The program should be revised :
func checkage(age: int?)->String
{
if let age_type = Int(age)
{
if age_type > 18 {
return "Welcome!"
}
else if age_type < 18 {
return"Sorry, but you aren't old enough to use our app."
}
}
else {
return "Sorry, something went wrong. Can you please re-enter your age?"
}
return age_type
}
We call the functions :
checkage(userInputAge)
checkage("15")
Note: we revised the program for errors in the first line of the code where the int optional parameter(int?) was supposed to be used instead of the String parameter in the function. We then called the function using the userInputAge variable defined as the parameter and then we now also used a String as the parameter for calling the function the second time.
Answer:
def checkage(age: "String")->int:
if age >= 18:
return "Welcome!"
return "Sorry, but you aren't old enough to use our app."
for _ in iter(list,0):
myage = int(input("Please enter your age: "))
if myage is int(myage):
result = checkage(myage)
print(result)
break
print("Sorry, something went wrong. Enter integer value as age.")
Explanation:
The python code above lets the user input the age value for continuous comparison. If the age is an integer, it checks to know if the age is greater than 18 or not. If yes, it returns "Welcome!" else "Sorry, but you aren't old enough to use our app". But if the age is not an integer, it displays the message "Sorry, something went wrong. Can you please re-enter your age?" then prompts the user again for the age.
Note: the ': "String" ' and "->int" is for documentation purposes. They are used to describe the type of parameters (for later) and return value (the former).

In the rapid application development (RAD) model, the _____ phase focuses on program and application development tasks similar to the SDLC.A) requirements planningB) user designC) constructionD) cutover
Answer:
C) construction
Explanation:
Rapid application development abbreviated RAD is an agile software development strategy that reduces time spent on planning so that prototype development takes priority and project turnaround time is greatly reduced consequently. There are four phases in rapid application development :
requirements planning, user design, construction, cutover
The construction phase is the third stage in rapid application development. This stage builds on the progress of the previous stages- the requirements planning stage and user design stage- to go ahead to finalize the application development which has been agreed on through iterations and communication between developer and client in the user design stage. In other words, this stage basically takes the ideas, prototypes and beta products from the previous stages and makes it into a real final product. The rationale or perks behind this is that other problems such as what product would do or look like or any changes or modifications have been worked out in previous stages thereby speeding up development in this stage.
