Answer:
b. 2.9!
Explanation:
There are is a mistake in the question.
Suppose the group consist of 10 kids and 2 adults, the number of ways in which they can form the line is:
= 2! 10!
= 2× 1× 10!
= 2.10!
But since that is not in the given option.
Let assume that the group consists of 9 kids and 2 adults, the number of ways in which they can form the line is:
No of ways the kids can be permutated = 9 ways
No of ways the adult can be permutated = two ways.
Thus; the number of ways in which they can form the line = 2! 9!
= 2 × 1× 9!
= 2.9!
Answer:
Let the two string type variables be var1 and var2. The value stored in these two variables is : The "use" of quotations causes difficulties.
- The variable which uses quoted string:
string var1 = "The \"use\" of quotations causes difficulties.";
- The variable which does not use quoted string:
string var2 = "The " + '\u0022' + "use" + '\u0022' + " of quotations causes difficulties.";
- Another way of assigning this value to the variable without using quoted string is to define a constant for the quotation marks:
const string quotation_mark = "\"";
string var2 = "The " + quotation_mark + "use" + quotation_mark + " of quotations causes difficulties.";
Explanation:
In order to print and view the output of the above statements WriteLine() method of the Console class can be used.
Console.WriteLine(var1);
Console.WriteLine(var2);
In the first statement escape sequence \" is used in order to print: The "use" of quotations causes difficulties. This escape sequence is used to insert two quotation marks in the string like that used in the beginning and end of the word use.
In the second statement '\u0022' is used as an alternative to the quoted string which is the Unicode character used for a quotation mark.
In the third statement a constant named quotation_mark is defined for quotation mark and is then used at each side of the use word to display it in double quotations in the output.

Answer:
number = int(input("Enter number: "))
if (number % 4):
print("{} is not divisible by 4".format(number))
else:
print("{} is divisible by 4".format(number))
Explanation:
If the %4 operation returns a non-zero number, there is a remainder and thus the number is not divisable by 4.
