In a switch statement, if a break statement is missing, _______________. Select one: a. the default case is automatically execut

Aleks [24]

Answer:

c. execution falls through the next branch until a break statement is reached

Explanation:

In a switch statement, if break is missing, then program continues to the next cases until it finds a break statement.

Consider the following example!

Example:

#include <iostream>

using namespace std;

int main()

{

int choice = 1;

switch (choice)

{

case 1:

printf("This is case 1, No break\n");

case 2:

printf("This is case 2, No break\n");

case 3:

printf("This is case 3, with break\n");

break;

default: printf("Error! wrong choice\n");

}

return 0;

}

Output:

This is case 1, No break

This is case 2, No break

This is case 3, with break

We have 3 cases here and case 1 and 2 don't have break statements, only case 3 has a break statement.

We called the case 1, then program continued to case 2, and finally to case 3 where it finds the break statement and terminates.

Therefore, we conclude that in a switch statement, if a break statement is missing, then execution falls through the next branch until a break statement is found.

a password to a certain database consists of digits that cannot be repeated. if the password is known to consist of at least 8 d

BaLLatris [955]

Answer:

$\frac{10!}{2}mins$

Explanation:

12 seconds to try one combination will be equivalent to $\frac{1}{12}\times 60 = \frac{1}{5} \ mins$

Password contain at least 8 digit i.e. password can contain 8, 9, 10 digit.

Password cannot contain more than 10 digit because it will give room for repetition which it is clearly stated that digit cannot be repeated.

Possible digit that can be used: 9,8,7,6,5,4,3,2,1,0.

Total number of passwords combination possible for each position in 8 digit.

1st position = 10, 2nd position = 9, 3rd position = 8, 4th position = 7, 5th position = 6, 6th position = 5, 7th position = 4, 8th position = 3. Total number of passwords combination possible in 8 digit is equivalent to $\frac{10!}{2}$ .

Total number of passwords combination possible for each position in 9 digit.

1st position = 10, 2nd position = 9, 3rd position = 8, 4th position = 7, 5th position = 6, 6th position = 5, 7th position = 4, 8th position = 3, 9th position = 2. Total number of passwords combination possible in 9 digit is equivalent to $\frac{10!}{1}$ .

Total number of passwords combination possible for each position in 10 digit.

1st position = 10, 2nd position = 9, 3rd position = 8, 4th position = 7, 5th position = 6, 6th position = 5, 7th position = 4, 8th position = 3, 9th position = 2, 10th position = 1. Total number of passwords combination possible in 10 digit is equivalent to 10!.

Adding them up and multiplying by $\frac{1}{5} \ mins$ to get the total number of time needed to guarantee access to database = $[\frac{10!}{2}\times\ \frac{10!}{1} \times 10!] \frac{1}{5}\ mins = \frac{10!}{2}$

8. Given the array String[] words, which already contains 1 or more values, write a block of code which counts and returns the n

Vikentia [17]

Answer:

Following are the code to this question:

public class Main//defining a class

{

public static void main(String[] arg)//defining main method

{

String[] words={"Key","day", "Know", "kind"};//defining array of String words

int x=0;//defining integer variable for count value

for(int i=0;i<words.length;i++)//defining for loop for count value

{

if(words[i].startsWith("k")||words[i].startsWith("K"))//use if block to check word start from k

x=x+1;//increment the value of x

}

System.out.print("The number of letters which starts from k is: "+ x);//print value with message

}

}

Output:

The number of letters which starts from k is: 3

Explanation:

In this code, inside the main method an array of String "words" is defined that hold a value, and in the next step an integer variable "x" is defined, which is used to count the letters, which starts from k.

For this, a for loop is used that counts the value and in this an, if block is defined that uses the "startsWith" method to check the value and increment the value of x and at the last, it prints its value.
