Answer to Question #333565 in C++ for Rille

Question

Build a C++ program to read the temperature in centigrade and display a suitable message according to the temperature state below: (nested-if else/switch case)

Temp <0 then freezing weather

Temp 0-10 then very cold weather

Temp 10-20 then cold weather

Temp 20-30 then normal in Temp

Temp 30-40 then it is hot

Temp >=40 then it is very hot

Example Input: 42

Expected Output: It is very hot.

Answer 1

#include <iostream>
using namespace std;

int main() {
    int Temp;
    cout<<"Enter the temperature in centigrade: ";
    cin>> Temp;
    
     if(!cin){        // validation
        cout<<"Invalid input. Must be int number"<<endl;
        cin.clear();            // clears the error flag
        exit(1);
       }
    
    if(Temp<0)
        cout << "freezing weather";
    
    else if(Temp<10)
            cout << "very cold weather";
            
    else if(Temp<20)
            cout<<"cold weather";
            
    else if(Temp<30)
            cout<<"normal in Temp";
            
    else if(Temp<40)
            cout<<"it is hot";
            
    else
        cout<<"it is very hot";    
    
    cout<<endl;    
    return 0;
}
