Question

The power of the microwave can be calculated as follows: Power=Work Time Work is measured in joules (I) and time is measured in seconds (s), so power is expressed in joules per second (J/s) and also known as the watt (W). For example, assume that a microwave oven does 24,000 joules of work in 30 seconds. Then the power of the microwave is 800 J/s, or 800 W. Write a program that asks the user how much work does microwave do in joules and how much time it takes in seconds. It should then use a loop to display the total power at the determined time period. Use a user input validation to enforce the user to enter a value for work and time that are greater than 0. Here is an example of the output: How much work does microwave do in joules? O[Enter] How much time it takes in seconds? [Enter] Invalid Work value, Enter a value greater than zero: 24000 [Enter] Invalid Time value, Enter a value greater than zero: 80[Enter] Time(second) Power(watt) 20 40 60 80 1200 600 400 300

i need it in c++ coding

Using c ++ language

Answer 1

#include<iostream.h>
void main()
{
float power,work,time;
int i;
cout<<"How much work does microwave do in Joule?";
cin>>work;
if(work<=0)
{
cout<<"Invalid work value, Enter a value greater than zero: ";
cin>>work;
}
cout<<"How much time it takes in seconds?";
cin>>time;
if(time<=0)
{
cout<<"Invalid Time value, Enter a value greater than zero: ";
cin>>time;
}
cout<<"Time(seconds)"<<"\t"<<"Power(watt)";
for(i=20;i<=time;i=i+20)
{
power=work/i;
cout<<endl<<i<<"\t\t"<<power;
}
