C++ Input a list of people's heights (in inches) from the user (terminated by a 0) and find the average height. The average should be displayed with a single value after the decimal, always showing. Do not allow the user to input a value less than 0 and use a while loop for input validation. What happens to your program if the first height input is 0? If this causes a problem, fix it!

Can someone help with the loops and input validation so it works correctly?

#include

#include

using namespace std;

int main()

{

//Set Decimal places to 1

cout << fixed << setprecision(1) << showpoint;

//Declare Variables

double heights; //The entered height

int total_heights = 1; //Number of heights entered

int total = 0; //Accumulator

double average; //Average of the entered heights

cout << "Enter the height of person 1 " << endl;

cout << "then enter 0 when finished " << endl;

cin >> heights;

if (heights <= -1)

cout << "Invalid entry!" << endl;

else

{

while (heights != 0)

{

total += heights;

total_heights++;

cout << "Enter the height of person " << total_heights << endl;

cin >> heights;

{

if (heights <= -1)

{

cout << "Invalid entry!" << endl;

break;

}

}

average = total / (total_heights-1);

cout << "The average of the entered heights is " << average << endl;

return 0;

}

}
