if else statements

0.o · 09-27-2005, 02:01 PM

I know this seems like an easy problem to figure out, however, i am unable to see the problem. If one of you could so kindly point out where i am going wrong in my ways.

Code:

#include <iostream>
#include <conio>

using namespace std;

void main()
{
        cout<<"Control structures and the beach"<<endl;

        int temp, temp2;
        string day;
        bool sunny;

        cout<<"Please enter the same twice temperature: ";
        cin>>temp;


        if(temp >= 75){
               cout<<"Good temperature"<<endl;
        }
        else{
        cout<<"Kind of chilly out there!"<<endl;
        }
        if(temp >= 90){
        cout<<"Its a little hot out there"<<endl;
        }
        else if(temp >= 80){
        cout<<"Great weather, warm but not too warm"<<endl;
        }
        else if(temp < 70){
        cout<<"STAY HOME!"<<endl;
        }
        cout<<"If its sunny type true else type false: ";
        cin>>sunny;

        if(sunny==true && temp >= 90){
        cout<<"Go to the park"<<endl;
        }
        else if(sunny==true && temp >= 80){
        cout<<"Go to the beach"<<endl;
        }
        else{ if(sunny==false || temp < 70)
        cout<<"Go to the mall"<<endl;
        }
        cout<<"Press any key to conitinue"<<endl;
        getch();

}//end of main

I don't understand...what's the problem that you want us to find?

Sorry, i guess i should have stated that. When it executes, the first part that is above "cout<<"If its sunny type true else type false: ";" functions as you would think. However, below that doesn't work correctly. When it runs, no matter what data i input, it always tells me to go to the mall, and i don't want to go to the mall all the time.

void main() <---- no no

int main()

should always return something back to the os
this is not whats causing the error tho but just something to keep in mind.

Are you actually typing in "true" and "false" for that? If so, cin to a boolean doesn't work that way. Try typing 0 and 1 and that will input correctly to a boolean. Otherwise change it to a string and use if (str == "true").

Yes. I was typing "true" and "false" as input; although, I get the same output if i use 1 or 0.

Interesting, because I get no output unless I use 1 or 0. What are you typing in? Here's the output of what I get if I type the values that would match those if else statements:
Control structures and the beach
Please enter the same twice temperature: 80
Good temperature
Great weather, warm but not too warm
If its sunny type true else type false: 1
Go to the beach

Control structures and the beach
Please enter the same twice temperature: 90
Good temperature
Its a little hot out there
If its sunny type true else type false: 1
Go to the park

Control structures and the beach
Please enter the same twice temperature: 90
Good temperature
Its a little hot out there
If its sunny type true else type false: 0
Go to the mall
