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>

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
I don't quite understand what you are asking but if you are asking if word, spelling and grammar checkers are always 100% accurate then that is false :)
Infinity amount of answers because each side can be simplified to x making any solution correct
Answer:
b
Explanation:
First, we need to initialize the classifier.
Then, we are required to train the classifier.
The next step is to predict the target.
And finally, we need to evaluate the classifier model.
You will find different algorithms for solving the classification problem. Some of them are like decision tree classification etc.
However, you need to know how these classifier works. And its explained before:
You need to initialize the classifier at first.
All kinds of classifiers in the scikit-learn make use of the method fit(x,y) for fitting the model or the training for the given training set in level y.
The predict(x) returns the y which is the predicted label.And this is prediction.
For evaluating the classifier model- the score(x,y) gives back the certain score for a mentioned test data x as well as the test label y.
Answer:
web portals
Explanation:
B2B (business-to-business) is a marketing strategy that deals with meeting the needs of other businesses, by selling products or services to the organizations for resale to other consumers, used in production of goods or for the operation of an organisation.
B2B (business-to-business) model focuses on facilitating sales transactions between businesses.
Under the B2B, the producer sells its products directly to other businesses such as wholesalers or retailers and not the end consumers.
B2B partners often connect to each other on the Internet through special web portals that are designed to facilitate exchange of information and simplified business transactions.
Additionally, a popular application of the seller-side marketplace model, which is a major business-to-business (B2B) e-commerce model, is e-procurement of goods through the use of web portals over the internet and as such eliminating the option of physical buying or procurement.
