50 60

Explanation:

Given

The above code segment

Required

What is printed, if anything

To do this, we analyze the code line by line.

Line 1: The first line creates a 4 by 3 array named mat

Line 2: for (int[] row : mat) {  -> This creates row[] array which represents each row of array mat

Line 3: for (int j = 0; j < row.length; j += 2){ -> This iterates through the even indexed elements of the row array i.e. 0 and 2

Line 4: System.out.print(row[i] + " "); -> This prints the even indexed elements of the row array.

The even indexed elements are: 10, 20, 30, 40, 50 and 60

Line 5: System.out.println(); --> This prints a new line

Write a loop that reads c-strings from standard input where the c-string is either "land", "air", or "water". The loop terminate
Anvisha [2.4K]

Answer:

I am writing a C++ code.        

#include <iostream> // for input output functions

using namespace std; // identifies objects like cin cout

int main() { //start of main() function body

string c_string; // stores the string entered by user from land water or air

int land=0; // contains the number of times land string is read in

int air=0; //contains the number of times air string is read in

int water = 0; //contains the number of times water string is read in

cin>>c_string; //reads the string entered by user from air water or land

/*while loop continues to execute until user enters xxxxx or maximum length of a string exceeds 8 */

while(c_string!= "xxxxx" && c_string.length()<=8) {

if(c_string=="land"){ // if string entered by user is land

land = land + 1;} //counts and increments each occurrence of land string by 1

else if(c_string=="air"){// if string entered by user is air

air = air + 1;}// counts and increments each occurrence of string air by 1

else if(c_string=="water"){// if string entered by user is water

water = water + 1;}//counts and increments each occurrence of air by 1

cin>>c_string;}

/* keeps reading the string entered by user from land air or water, until the loop breaks after the user enters xxxxx or user enters a string whose length is greater than 8 */

//prints the number of times land, air and water are read in

cout << "land:"<<land;

cout << endl<<"air:"<<air;

cout << endl<< "water:"<<water; }                      

                                                                                     

Explanation:

Everything is well explained in the comments above.

The program prompts the user to input strings. These strings are either land air or water. The while loop continues to read the input strings until user enters xxxxx or the string entered by user exceeds the length 8. Both these terminating conditions are added in the while loop. After the loop terminates, the number of times land, air and water strings are read is displayed on the output screen. Any other string entered by user other than these 3 is ignored. The program along with the output is attached.

Write a Python function LetterGame() that repeatedly asks the user to input a letter. The function is to count the number of vow
kotegsom [21]

Answer:

def LetterGame():

   vowels = ["a", "e", "i", "o", "u", "A", "E", "I", "O", "U"]

   count1 = count2 = 0

   while True:

       choice = input("Enter a letter / digit to stop: ")

       if choice.isdigit():

           break

       elif choice.isalpha():

           count1 += 1

           if choice in vowels:

               count2 += 1

   print("You entered " + str(count1) + " letters, " + str(count2) + " of which weere vowels.")

   print("The percentage of vowels was " + str(count2 / count1 * 100) + "%")

LetterGame()

Explanation:

Create a function called LetterGame

Inside the function:

Create a list of vowels

Initialize count1, counts the total letters, and count2, counts the vowels

Initialize a while loop that iterates until the specified condition is met in the loop

Get the input from the user. If it is a digit, stop the loop. If it is an alphabet, increase the count1 by 1, and also check if it is a vowel. If it is a vowel, increment the count2 by 1

When the loop is done, print the required information

Finally, call the function
