It’s either the 2nd or 3rd one
It is true. The parameter that acquire the value and send a value outside function should be declared a reference parameter.
Its a glitch in the system i believe...try asking a teacher or maybe restarting your computer. or maybe just try again later
Answer:
// here is code in C++(bmi.cpp).
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variables
float weight,height;
cout<<"enter the weight(in kilograms):";
//read the weight
cin>>weight;
cout<<"enter the height(in meters):";
//read the height
cin>>height;
// calculate the bmi
float bmi=weight/(pow(height,2));
// print the body-mass index with two decimal places
cout<<"BMI is: "<<fixed<<setprecision(2)<<bmi<<endl;
return 0;
}
Explanation:
Read the weight from user and assign it to variable "weight",read height and assign it to variable "height".Then find the body-mass index as (weight/height^2).Here weight should be in kilograms and height should be in meters.
Output:
enter the weight(in kilograms):75
enter the height(in meters):1.8
BMI is: 23.15
Answer:
D
Explanation: i think it's d because today technology is a big thing it would make sense if there was machinery doing the work so in that case ).Factories filled with machinery and no need for employees.
