# 11/04 可憐的我被C++搞慘了

### 問題 (感覺是對的但是*WRONG ANS*)
1. TOJ98 (toj.tfcis.org/oj/pro/98/)

    #include<iostream>
    using namespace std;
    int main(){
    	long long c=299792458;

        cout<<"1 Light-second(LS) is "<<c<<" metres."<<'\n'
        <<"1 Light-minute(LM) is "<<c*60<<" metres."<<'\n'
        <<"1 Light-hour(LH) is "<<c*60*60<<" metres."<<'\n'
        <<"1 Light-day(LD) is "<<c*60*60*24<<" metres."<<'\n'
        <<"1 Light-week(LW) is "<<c*60*60*24*7<<" metres."<<'\n'
        <<"1 Light-year(LY) is "<<c*60*60*24*7*365<<" metres."<<'\n';

	    return 0;
    }

更:一年=c*60*60*24*365

2. TOJ102 (toj.tfcis.org/oj/pro/102/)

    #include<iostream>
    #include<iomanip>
    using namespace std;
    int main(){
    	double a,b;	char c;
    	cin>>a>>c>>b;
    	if (c== 43){
    		cout<<a<<" + "<<b<<" = "<<fixed<<setprecision(4) <<a+b<<'\n';
    	}
	    else if (c== 45){
		    cout<<a<<" - "<<b<<" = "<<fixed<<setprecision(4)<<a-b<<'\n';
	    }
	    else if (c== 42){
		    cout<<a<<" * "<<b<<" = "<<fixed<<setprecision(4)<<a*b<<'\n';
	    }
	    else if (b==0){
		    cout<<"ERROR"<<'\n';
	    }
	    else {
		    cout<<a<<" / "<<b<<" = "<<fixed<<setprecision(4)<<a/b<<'\n';
	    }

	return 0;
    }

3. TOJ103 (toj.tfcis.org/oj/pro/103/)

    #include<iostream>

    using namespace std;

    int main(){
	    string a,b;
	    int c,d;
	    cin>>a>>c>>b>>d;
	    if (a==b&&c==d)
    		cout<<"GOOD\n";
	    else if (a==b||c==d)
	    	cout<<"=~=\n";
	    else
	    	cout<<"OTZ\n";


    	return 0;
    }

4. TOJ107 (toj.tfcis.org/oj/pro/107/)

    #include<iostream>

    using namespace std;

    int main(){
    	long long n=0;
	    for (int i=1;i<=30;i++ ) {
	    	n+=(i+i+(i*(i+1)*i/2));
    	}
    	cout<<n<<'\n';


	    return 0;
    }

5. TOJ109 (toj.tfcis.org/oj/pro/109/)

    #include<iostream>

    using namespace std;

    int main(){
        int n,f;	cin>>n;
        for (int i=0;i<n;i++) {
            int a,b;
            cin>>a>>b;
            if (a==0) {
                if (b==2)
                    f--;
                else if (b==5)
                    f++;
            }
            else if (a==2) {
                if (b==0)
                    f++;
                else if (b==5)
                    f--;
            }
            else {
                if (b==0)
                    f--;
                else if (b==2)
                    f++;
            }
        }
        if (f==0)
            cout<<"The referee wins.\n";
        else if (f>0)
            cout<<"The princess wins.\n";
        else
            cout<<"The prince wins.\n";


        return 0;
    }

so that's it...
