Question
One way to estimate the height of a child is to use the following formula, which uses the height of the parents:
Hmale_child = ((Hmother 13 / 12) + Hfather) / 2
Hfemale_child = ((Hfather 12 / 13) + Hmother) / 2
ll heights are in inches. Write a function that takes as input parameters the gender of the child, height of the mother in inches, and height of the father in inches, and outputs the estimated height of the child in inches. Embed your function in a program that allows you to test the function over and over again until telling the program to exit. The user should be able to input the heights in feet and inches, and the program should output the estimated height of the child in feet and inches. Use the integer data type to store the heights.
Answer
PROGRAM CODE:
//Header section
#include <iostream>
using namespace std;
// Function to estimate the height of a child
int estimateChildHeight(char gender, int motherHeight, int fatherHeight) {
int childHeight;
// Calculate the estimated height based on the gender of the child
if (gender == 'M') {
childHeight = ((motherHeight * 13 / 12) + fatherHeight) / 2;
} else if (gender == 'F') {
childHeight = ((fatherHeight * 12 / 13) + motherHeight) / 2;
} else {
// Invalid gender input
cout << "Invalid gender input. Please enter 'M' for male or 'F' for female." << endl;
return 0;
}
return childHeight;
}
// Function to convert inches to feet and inches
void convertToFeetAndInches(int inches, int& feet, int& remainingInches) {
feet = inches / 12;
remainingInches = inches % 12;
}
int main() {
char gender;
int motherHeightFeet, motherHeightInches;
int fatherHeightFeet, fatherHeightInches;
while (true) {
// Get the inputs from the user
cout << "Enter the gender of the child (M-MALE/F-FEMALE/E-EXIT): ";
cin >> gender;
// Check if the user wants to exit
if (gender == 'E') {
cout << "Exiting the program..." << endl;
break;
}
cout << "Enter the height of the mother (feet inches): ";
cin >> motherHeightFeet >> motherHeightInches;
cout << "Enter the height of the father (feet inches): ";
cin >> fatherHeightFeet >> fatherHeightInches;
// Convert heights to inches
int motherHeight = motherHeightFeet * 12 + motherHeightInches;
int fatherHeight = fatherHeightFeet * 12 + fatherHeightInches;
// Estimate the height of the child
int childHeight = estimateChildHeight(gender, motherHeight, fatherHeight);
// Convert child height to feet and inches
int childHeightFeet, childHeightInches;
convertToFeetAndInches(childHeight, childHeightFeet, childHeightInches);
// Display the estimated height of the child
cout << "Estimated height of the child: " << childHeightFeet << " feet " << childHeightInches << " inches" << endl;
cout << "----------------------------------------------" << endl;
}
return 0;
}
OUTPUT OF THE PROGRAM CODE:
Enter the gender of the child (M-MALE/F-FEMALE/E-EXIT): M
Enter the height of the mother (feet inches): 5 1
Enter the height of the father (feet inches): 6 1
Estimated height of the child: 5 feet 9 inches
----------------------------------------------
Enter the gender of the child (M-MALE/F-FEMALE/E-EXIT): F
Enter the height of the mother (feet inches): 5 0
Enter the height of the father (feet inches): 6 0
Estimated height of the child: 5 feet 3 inches
----------------------------------------------
Enter the gender of the child (M-MALE/F-FEMALE/E-EXIT): E
