Answer: The standard web component layouts and templates makes the web page seem like many others but could also make it easier for users to interact and use the web page without much trouble. The approaches do limit creativity and originality in web page design but its better to have an easy to use web page that can still look good rather than something that is confusing for the users.
Explanation:
Answer:
b. size
Explanation:
We can use the size() method of java.util.ArrayList to determine the size of an ArrayList in Java. The size() method of the ArrayList class returns an integer which is equal to the number of elements present in the ArrayList.
Below is an example code to illustrate the use of the size() method of the ArrayList:-
ArrayList<Integer> aList = new ArrayList<Integer>(5);
aList.add(25);
aList.add(2);
aList.add(5);
aList.add(22);
System.out.println("Size of the array list: " + aList.size());
This will print the size of the array list as 4 since we've added four numbers into the array list.
Answer: False.
Explanation:
The general case of recursive function is when the solution is obtained recursively by simplification at each step.
However, it is the base case in a recursive function when the solution is obtained directly.
The general case must be reducible to base to arrive at a solution else the recursion would be a infinite recursion.
Answer:
Python Code:-
#creating a list
current_members = [4, 6, 9]
#defining the variable
#assigning the value
member_id = 9
#defining variable count
count = 0
#defining the variable and setting initial value to true
is_a_member = False
#for loop is used to iterate over the list
for x in current_members:
#if statement will check whether the element is found
if x == member_id:
#set the value to true if the value is matched
is_a_member = True
#set the value to 1
count = 1
#if count == 0
#set the value of is_a_member variable to false
if count == 0:
is_a_member = False
#print the current value stored in is_a_member variable
print(is_a_member)
Explanation:
In the above python program, a list is created that is "current_members" and some values are inserted. In the next line, a three-variable is defined that are member_id, count, and is_a_member.
- In both variable member_id, count assigns some value. and in is_a_member variable assign a False value.
- Using a for loop to iterate over the list.
- Inside the loop, If the statement will check whether the element is found. Then set the value of is_a_member variable to True and count to 1.
- Another if the statement is used which checks the value of the count variable. If the value of count is 0 then set the value of is_a_member to False.
- print() function is used to display the current value of is_a_member variable.
