Question

Transcribed Image Text:**Summary**
In this lab, the completed program should print the numbers 0 through 10, along with their values multiplied by 2 and by 10. You should accomplish this using a `for` loop instead of a counter-controlled `while` loop.
**Instructions**
1. Write a `for` loop that uses the loop control variable to take on the values 0 through 10.
2. In the body of the loop, multiply the value of the loop control variable by 2 and by 10.
3. Execute the program by clicking the Run button at the bottom of the screen. Is the output the same?

**C++ Code Explanation**
The provided code segment is in C++:
```cpp
#include <iostream>
#include <string>
using namespace std;
int main()
{
string head1 = "Number: ";
string head2 = "Multiplied by 2: ";
string head3 = "Multiplied by 10: ";
int numberCounter; // Numbers 0 through 10
int byTen; // Stores the number multiplied by 10
int byTwo; // Stores the number multiplied by 2
const int NUM_LOOPS = 10; // Constant used to control loop
// This is the work done in the housekeeping() function
cout << "0 through 10 multiplied by 2 and by 10." << endl;
// This is the work done in the detailLoop() function
// Write your for loop here.
// This is the work done in the endOfJob() function
return 0;
} // End of main()
```
**Explanation:**
- **Headers Included:**
- `<iostream>`: For input-output stream operations.
- `<string>`: For using string data types.
- **Namespace:**
- `using namespace std;`: To avoid prefixing standard library functions with `std::`.
- **Main Function:**
- Declares three string variables for headings.
- `int numberCounter;` is intended for iterating numbers from 0 to 10.
- `int byTen;` and `int byTwo;` to store multiplication results.
- `const int NUM_LOOPS = 10;` is a constant to control

- Turtle Drawing with Loops Objective: To make a drawing using turtle graphics and nested loops Requirements: -Your program should ask the user at least two questions, and use the answers to help make the drawing. -Your program must have at least one pair of nested loops (a loop inside of a loop) to do some of the drawing -Your drawing cannot be made up only of rotated polygons coming from the center of the screen like we did in class. -Please write a new program for this assignment - don't use code from any in-class exercises. -For example, your program could draw a field of flowers, or you could draw a repetitive square pattern like you might see on a rug.arrow_forward// LargeSmall.cpp - This program calculates the largest and smallest of three integer values. #include <iostream> using namespace std; int main() { // This is the work done in the housekeeping() function // Declare and initialize variables here int largest; // Largest of the three values int smallest; // Smallest of the three values // Prompt the user to enter 3 integer values // Write assignment, add conditional statements here as appropriate // This is the work done in the endOfJob() function // Output largest and smallest number. cout << "The largest value is " << largest << endl; cout << "The smallest value is " << smallest << endl; return 0; }arrow_forwardpls debug this pseudocode // A high school is holding a recycling competition,// and this program allows a user to enter a student's // year in school (1 through 4) and number of cans collected// for recycling.
