Answer to Question #273617 in C++ for Nick

Question

Absolute zero is the lowest temperature that can be reached; it is -273.15°c, or 0k. The above preogram, even when corrected l, will produce erroneous results when given a temperature below zero, Place a check in the main program that will produce an error if a temperature is given below -273.15°c.

Answer 1

#include <iostream>
using namespace std;
int main()
{
    signed long a= -273.15, b;
    // prompt user to enter temperature in degree celcius 
    cout<<"Enter temperature in degree celcius:";
    cin>>b;
    /* use if condition statement to check if the entered temperature is less that the given temperature*/
    if(b<a){
        cout<<"Error!!!";
    }
    else{
        cout<<"The temperature is above  -273.15";
    }
    
    cout<<b;
    return 0;
}
