Andru [333]

Answer:

Following are the program in the C++ Programming Language.

//set header file or namespace

#include <iostream>

using namespace std;

//define main function

int main() {

//set integer type array with indexing 10

int a[10];

//set integer type variable to 1

int i=1;

//set element in 1st index

a[0]=17;

//set element in last index

a[9]=29;

//set while loop for the remaining elements

while(i<9)

{

//set -1 in the remaining elements

a[i]=-1;

i++;

}

//set for loop to print array

for ( int j = 0; j < 10; j++ ) {

cout << a[j]<<endl;

}

<u>Output:</u>

17

-1

29

Explanation:

In the following program, we define the main function "main()" and inside it.

Set an integer type array element "a[]" with index value 10.
Set integer data type variable "i" initialize to 1.
Set elements in the first and last place in the array.
Set the while loop to initialize elements for the remaining place.
Set the for loop to print the array elements.

Prompt the user to input an integer, a double, a character, and a string, storing each into separate variables. Then, output tho

kotegsom [21]

Answer:

import java.util.Scanner;

public class ANot {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

// Prompt user for an integer

System.out.println("Please enter an Integer");

int intNum = in.nextInt();

// Prompt user for an double

System.out.println("Please enter a double");

double DoubleNum = in.nextDouble();

// Prompt user for a character

System.out.println("Please enter a Character");

char charNum = in.next().charAt(0);

// Prompt user for a String

System.out.println("Please enter a String");

String StringNum = in.next();

System.out.println(intNum+" "+DoubleNum+" "+charNum+" "+StringNum);

}

Explanation:

We import the Scanner class in order to receive user input. Then we create four different variables of type int, double,char and String to hold the values entered by the user.

To display the output on a single line, we use string concatenation (using the + operator) to acheive this.

A farmer sells tomatoes. For some reason, the farm obeys mechanical laws of fate.

Mars2501 [29]

Answer:

Here are the if/elif statements:

if tomatoes == 24: #if farmer sells exactly two dozen tomatoes

watermelons +=4 #farmer receives 4 watermelons

elif tomatoes >= 12: #else farmer sells at least a dozen tomatoes

watermelons +=2 #farmer receives 2 watermelons

else:

tomatoes<12 #On the days that farmer sells less than a dozen tomatoes

apples +=1 #farmer will get a single apple

Explanation:

You can test the working of these if elif statements by this program:

tomatoes = int(input("Enter the amount of tomatoes sold: ")) #prompts user to enter number of tomatoes

watermelons = 0 #initialize watermelons value to 1

apples = 0 #initialize apples value to 1

if tomatoes == 24:

watermelons +=4

elif tomatoes >= 12:

watermelons +=2

else:

tomatoes<12

apples +=1

print("Number of watermelons recieved: ",watermelons) #displays the received number of watermelons

print("Number of apples recieved: ",apples ) #displays the received number of apples
