In this lab, you add a loop and the statements that make up the loop body to a C++ program that is provided. When completed, the program should calculate two totals: the number of left-handed people and the number of right-handed people in your class. Your loop should execute until the user enters the character X instead of L for left-handed or R for right-handed. The inputs for this program are as follows: R, R, R, L, L, L, R, L, R, R, L, X Variables have been declared for you, and the input and output statements have been written. Instructions Ensure the source code file named LeftOrRight.cpp is open in the code editor. Write a loop and a loop body that allows you to calculate a total of left-handed and right-handed people in your class. Execute the program by clicking the Run button and using the data listed above and verify that the output is correct. **GIVEN CODE** #include using namespace std; int main(){ string leftOrRight = ""; // L or R for one student. int rightTotal = 0; // Number of right-handed students. int leftTotal = 0; // Number of left-handed students. // This is the work done in the housekeeping() function cout << "Enter an L if you are left-handed, a R if you are right-handed or X to quit: "; cin >> leftOrRight; // This is the work done in the detailLoop() function // Write your loop here. int i=0; char left='L'; char right='R'; char key='X'; while((leftOrRight[i]!=key) && (leftOrRight[i]==left || leftOrRight[i]==right)){ if(leftOrRight[i]==left) leftTotal++; //incrementing leftCount if letter is L else if(leftOrRight[i]==right) rightTotal++; //incrementing RightCount if letter is R i=i+2; // loop variable is incremented by 2 to avoid checking with "," } // This is the work done in the endOfJob() function // Output number of left or right-handed students. cout << "Number of left-handed students: " << leftTotal << endl; cout << "Number of right-handed students: " << rightTotal << endl; return 0; }

Instructions

Ensure the source code file named LeftOrRight.cpp is open in the code editor.
Write a loop and a loop body that allows you to calculate a total of left-handed and right-handed people in your class.
Execute the program by clicking the Run button and using the data listed above and verify that the output is correct.

**GIVEN CODE**

#include<iostream>

using namespace std;

int main(){

string leftOrRight = ""; // L or R for one student.

int rightTotal = 0; // Number of right-handed students.

int leftTotal = 0; // Number of left-handed students.

// This is the work done in the housekeeping() function

cout << "Enter an L if you are left-handed, a R if you are right-handed or X to quit: ";

cin >> leftOrRight;

// This is the work done in the detailLoop() function

// Write your loop here.

int i=0;

char left='L';

char right='R';

char key='X';

while((leftOrRight[i]!=key) && (leftOrRight[i]==left || leftOrRight[i]==right)){

if(leftOrRight[i]==left)

leftTotal++; //incrementing leftCount if letter is L

else if(leftOrRight[i]==right)

rightTotal++; //incrementing RightCount if letter is R

i=i+2; // loop variable is incremented by 2 to avoid checking with ","

}

// This is the work done in the endOfJob() function

// Output number of left or right-handed students.

cout << "Number of left-handed students: " << leftTotal << endl;

cout << "Number of right-handed students: " << rightTotal << endl;

return 0;
