Help with complex if statements

Code:

---

#include <iostream.h>
int main()
{
        int myLook;
        cout << "Rate my looks on a scale from 1 to 10\n";
        cin >> myLook;
        {
        if (myLook == 1)
                cout << "1\n";
        if (myLook == 2)
                cout << "2\n";
        if (myLook == 3)
                cout << "3\n";
        if (myLook == 4)
                cout << "4\n";
        if (myLook == 5)
                cout << "5\n";
        if (myLook == 6)
                cout << "6\n";
        if (myLook == 7)
                cout << "7\n";
        if (myLook == 8)
                cout << "8\n";
        if (myLook == 9)
                cout << "9\n";
        if (myLook == 10)
                cout << "10\n";
        return 0;
        }
}

uhh I basically want to make it so if you type in a number it will say something I have it set to say the number you type in right now, I want it so if you type in a number that is not between 1-10 that it says error or something, could someone give me some ideas or examples of what I could do to make this work the way I want it to?

Thanks

I would use a switch statement.

Code:

---

#include <iostream.h>

int main()
{
        int myLook;

        cout << "Rate my looks on a scale from 1 to 10\n";
        cin >> myLook;
       
        switch (myLook)
        {
                case 1:
                        cout << "1\n";
                        break;
                case 2:
                        cout << "2\n";
                        break;
                case 3:
                        cout << "3\n";
                        break;
                case 4:
                        cout << "4\n";
                        break;
                case 5:
                        cout << "5\n";
                        break;
                case 6:
                        cout << "6\n";
                        break;
                case 7:
                        cout << "7\n";
                        break;
                case 8:
                        cout << "8\n";
                        break;
                case 9:
                        cout << "9\n";
                        break;
                case 10:
                        cout << "10\n";
                        break;
                default:
                        cout << "Please enter a number between 1 and 10.\n";
        }

        return 0;

}

hmm that works :) was trying to get something working using if and else statements... reading a book and havent yet gotten to switch statements :\

Thanks for help

Well, you can use if and else if's as well, but generally a switch block is considered easier to read, especially with your type of example.

Code:

---

#include <iostream.h>

int main()
{
        int myLook;

        cout << "Rate my looks on a scale from 1 to 10\n";
        cin >> myLook;

        if (myLook == 1)
                cout << "1\n";
        else if (myLook == 2)
                cout << "2\n";
        else if (myLook == 3)
                cout << "3\n";
        else if (myLook == 4)
                cout << "4\n";
        else if (myLook == 5)
                cout << "5\n";
        else if (myLook == 6)
                cout << "6\n";
        else if (myLook == 7)
                cout << "7\n";
        else if (myLook == 8)
                cout << "8\n";
        else if (myLook == 9)
                cout << "9\n";
        else if (myLook == 10)
                cout << "10\n";
        else
                cout << "Please enter a number between 1 and 10.\n";


        return 0;
}

Why not just use cout << mylook << endl ?

Because he wants a number from 1 to 10?

then Bebo could use

Code:

---

int myLook;
cout<<"Enter a Number"<<endl;
cin>>myLook;
if(myLook<=10)
cout<<myLook;

I just assumed that outputting the number again was an example, not the actual purpose of the program.

:)

Oh. An array could be used for a lookup, as well :)

Meh, he hasn't even gotten to switch yet.

:p

why should switch be taught before arrays? :p

I don't know, its a crazy world.

Not before arrays, but before using arrays as lookup tables.

Code:

---

int myLook;
cout<<"Enter a Number"<<endl;
cin>>myLook;
if(myLook<=10)
cout<<myLook;

---

should be

Code:

---

int myLook;
cout<<"Enter a Number"<<endl;
cin>>myLook;
if(myLook<=10 && myLook >=1)
  cout<<myLook;
else
  cout << "Enter a number between 1 and 10" << endl;

---

And it should include <iostream>, not <iostream.h>:

Code:

---

#include <iostream>
using namespace std;
