Answer:
<em>(c) The method call, which worked correctly before the change, will now cause a run-time error because it attempts to access a character at index 7 in a string whose last element is at index 6.</em>
<em />
Explanation:
Given
printAllCharacters method and printAllCharacters("ABCDEFG");
Required
What happens when x < str.length() is changed to x <= str.length()
First, we need to understand that str.length() gets the length of string "ABCDEFG"
There are 7 characters in "ABCDEFG".
So: str.length() = 7
The first character is at index 0 and the last is at index 6
Next, we need to simplify the loop:
for (int x = 0; x< str.length(); x++) means for (int x = 0; x< 7; x++)
The above loop will iterate from the character at the 0 index to the character at the 6th index
while
for (int x = 0; x<=str.length(); x++) means for (int x = 0; x<=7; x++)
The above loop will iterate from the character at the 0 index to the character at the 7th index
Because there is no character at the 7th index, the loop will return an error
Hence: (c) is correct
Answer:
double arrow shape
Explanation:
To adjust the height of the cells
1. We have to position the mouse pointer over one of the column line or the one of the row line.
2. As we place the pointer between the dividing lines, the cursor of the mouse pointer change from singe bold arrow to double arrow symbol.
3.Now press or click the left mouse button and drag the dividing lines of the cells to the desired position to have the required width or height of the cell.
Answer:
xyz = 25
result = square(xyz)
print(result)
The above code assigns the value 25 to variable xyz as 5*5=25. Then next statement is a function call to square() function passing xyz to this function in order to compute the square of 25. The output is:
625
Explanation:
The above code can also be written as:
xyz = 5*5
result = square(xyz)
print(result)
The difference is that xyz is assiged 5*5 which is equal to 25 so the output produced will be the same i.e. 625.
The result variable is used to store the value of square of 25 after the square() method computes and returns the square of 25. So print(result) prints the resultant value stored in the result variable i.e. 625
Answer:
A.
Explanation:
Based on the information provided within the question it can be said that in this scenario, Jupiter's best move would be to adopt the measure of ensuring that customers find its software simpler and more convenient to use than that of Coral. This would create satisfaction among the customers which in term would lead to customer loyalty.
Answer:
Correct code for the above question which is written after the defined list to display the output.
for x,y in country_pop.items(): #for loop to prints the list items.
print(str(x)+" has "+str(y)+" people") #print function to print the value.
Output:
- The above code is in python language which display the output as the above question demands.
Explanation:
- The above question code is written in python language to display the result, but this code is not correct.
- The above code needs a 'for' loop, which will render the list item one by one.
- The above-list defined in the form of key-value pair, So there is a need for the ''item" function which is the part of the python dictionary to display the list items.
- There also needs to define the two variables in the for loop, one is for key and the other is for value.
