Defining a for loop that checks "i" value in between 20, inside this it calculates power of two.
At the last use print method to print its value.

Program:

i=1#holding integer value in i

for i in range(20):#defining a for that starts 1 to 20

i = 2 ** i#calculate power of 2 in i variable

print(i)#print value

Write a program that lets the Michigan Popcorn Company keep track of their sales for seven different types of popcorn they produ

valentina_108 [34]

#include <iostream>
using namespace std;
int main()
{
// declare and initialize popcorn name array
string popcorn_name[7] = {"plain", "butter", "caramel", "cheese", "chocolate", "turtle", "zebra"};
// declare and initialize sales array with 7 elements
int sales[7];
// A loop to prompt user to enter sales for each popcorn
for(int i=0; i < 7; i++){
cout<<"Enter number of sales for " + popcorn_name[i] + " :";
cin>>sales[i];
}
// Find maximum sales
int max = sales[0];
int maxIndex = 0;
for(int j=1; j < 7; j++){
if(max < sales[j]){
max = sales[j];
maxIndex = j;
}
}
// Find minimum sales
int min = sales[0];
int minIndex = 0;
for(int k=1; k < 7; k++){
if(min > sales[k]){
min = sales[k];
minIndex = k;
}
}
// Print popcorn name and sales
for(int l=0; l < 7 ; l++){
cout<<popcorn_name[l]<<"\n";
cout<<"Sales: "<< sales[l]<<"\n\n";
}
// Print popcorn name with maximum and minimum sales
cout<<"Highest selling: "<< popcorn_name[maxIndex]<<"\n";
cout<<"Lowest selling: "<<popcorn_name[minIndex]<<"\n";
return 0;
}

Explanation:

Create two arrays to hold the list of popcorn name and their sales (Line 5-8). Next prompt user to input the sales for each popcorn (Line 10-14). Get the maximum sales of the popcorn (Line 17-24) and minimum sales (Line 27-34). Print the popcorn name and sales (Line 37-40) and the popcorn name with highest and lowest selling (Line 43-44).

Write a public static method diagSum, which takes a 2d array of int values as a parameter, and returns the sum of the elements i

saveliy_v [14]

A 2d array (i.e. 2 dimensional array) represents its elements in rows and columns

<h3>The program in Java</h3>

The method in Java, where comments are used to explain each line is as follows

//This defines the method

public static int diagSum(int[][] myArray) {

//This initializes sum to 0

int sum = 0;

//This iterates through each row of the array

for (int i = 0; i < myArray.length; i++) {

//This calculates the sum of the diagonals

sum+=myArray[i][i];

}

//This returns the sum

return sum;
