The correct answer is: A do-while loop contains only one statement between the do statement and the while statement.
A do-while loop is a control flow statement that allows you to repeat a block of code as long as a condition is true. The syntax for a do-while loop is as follows:
do {
// statement(s) to be executed
} while (condition);
The statement(s) inside the do-while loop will be executed at least once, even if the condition is false. This is because the condition is checked at the end of the loop, after the statement(s) have been executed.
Here is an example of a do-while loop:
int i = 0;
do {
cout << i << endl;
i++;
} while (i < 10);
This loop will print the numbers from 0 to 9. The statement cout << i << endl; will be executed at least once, even though the condition i < 10 is false at the beginning of the loop. This is because the condition is checked at the end of the loop, after the statement has been executed.
The other options are incorrect because they do not accurately describe the structure of a do-while loop. Option B states that a do-while loop contains several statements between the do statement and the while statement. This is not always the case. A do-while loop can contain only one statement, or it can contain multiple statements. Option C states that a do-while loop contains no statement at all between the do statement and the while statement. This is also not always the case. A do-while loop must contain at least one statement, even if it is just a simple statement like ;. Option D states that a do-while loop contains only two statements between the do statement and the while statement. This is not always the case. A do-while loop can contain any number of statements, as long as there is at least one statement. Option E states that none of the above is the correct answer. This is also incorrect, as the correct answer is A.
