Question

Write a program (code) that performs the following: Height and Weight for Male and Female: Robinson formula to calculate the body relative to the height in inches is as follow: Ideal weight in kilogram = 52 + 1.9 * (height - 60) for male Ideal weight in kilogram = 49 + 1.7 * (height - 60) for female Write a program that prompts the user to enter the gender ('M' or 'm' for male and 'F' or feet and inches, then calculates and prints the weight in kilograms, if the user enters a 'Invalid gender|".

Answer 1

//Program is given below and it is written in c++

#include <iostream>

using namespace std;

int main()
{
   char gender;
   int feet,inch,height;
   float weight;
   //prompt and accept gender from user
   cout<<"Enter the gender M or m for male and F or f for female:";
   cin>>gender;
   //if gender input from user is wrong print Invalid user and terminate
   if(gender!='M'&& gender!='m' && gender!='F' && gender!='f')
   {
        cout<<"Invalid gender!";
        return 0;
   }
   //prompt and accept height from user
   cout<<"Enter the height in feet and inches:";
   cin>>feet>>inch;

   height=feet*12+inch; //convert height in inches

   //calculate ideal weight for male and print
   if(gender=='M'||gender=='m')
   {
   weight=52+1.9*(height-60);
   cout<<"The ideal weight for a "<<height<<" inches male is "<<weight;
   }

   //calculate ideal weight for female and print
   if(gender=='F'||gender=='f')
   {
   weight=49+1.7*(height-60);
   cout<<"The ideal weight for a "<<height<<" inches female is "<<weight;
   }

   return 0;
}
