Whats wrong with this code?

Code:

---

#include <iostream>

using namespace std;

int main()
cint >> x;
{
        switch (x) {;
        Case 1:
                cout << "X = 1";
                Case 2:
                        Cout << "x=2";
                                Case 3:
                                        cout << "x =3";
                                        Case else
                                                cout << "x =";
                                        cout << n;
    }
        system( "pause" )
                return 0;
}

i get this:

Its before the opening '{' following the 'main' function. Plus i think you want 'cin' not 'cint'

Don't forget that with a case statement, the code will run all code from the first matching case statement. For example if x is 1 it'll run all of the case statements.
Use the 'break' keyword to get out of the switch statement after you've done stuff specific to that case.

Code:

---

#include <iostream> //<iostream.h> is deprecated

using namespace std;

int main()
cin >> x;
{
        switch (x) {;
        Case 1:
                cout << "X = 1";
                break;
                Case 2:
                        Cout << "x=2";
                        break;
                                Case 3:
                                cout << "x =3";
                                        break;
                                        Case else
                                                cout << "x =";
                                                        cout << n;
                                                                break;
    }
        system( "pause" )
                return 0;
}

thanks for the break, but can you explain this, or show me how youd do it:
ts before the opening '{' following the 'main' function. Plus i think you want 'cin' not 'cint'

C++ is case-sensitive. You must write "case".

Code:

---

int main()
cin >> x;
{

---

You've got the order of the lines mixed up here. The "{" should be before the "cin >> x;"

Code:

---

        switch (x) {;

---

This semicolon is misplaced.

Code:

---

Case else

---

"case else" doesn't exist. It's called "default" and needs a colon like all the case marks.

thanks, (case else = vb :D )

Code:

---

#include <iostream> //<iostream.h> is deprecated

using namespace std;

int main();
{
cin >> x;

switch(x){ ;
        Case 1:
                cout << "X = 1";
                break;
                Case 2:
                        Cout << "x=2";
                        break;
                                Case 3:
                                cout << "x =3";
                                        break;
                                        default;
                                                cout << "x =";
                                                        cout << n;
                                                                break;
    }
        system( "pause" )
                return 0;
}

You didn't remove the semicolon as I told you, and there's another wrong one at the end of the main() line.

Code:

---

#include <iostream> //<iostream.h> is deprecated

using namespace std;

int main()
{
cin >> x;

switch(x){
        Case 1:
                cout << "X = 1";
                break;
                Case 2:
                        Cout << "x=2";
                        break;
                                Case 3:
                                cout << "x =3";
                                        break;
                                        default;
                                                cout << "x =";
                                                        cout << n;
                                                                break;
    }
        system( "pause" );
                return 0;
}

Ever seen what happens when you enable Option Strict in VB?

'Case' : undeclared identifier

It's a matter of case. (BTW, that's the second time I need to tell you this.)

All C2143 errors are follow-ups.

'n' : undeclared identifier

Big surprise, when you called the variable 'x' earlier.

I think you need to unlearn VB before you can learn C++. I also think you need to learn to read the answers to your questions and apply what is in there - everything, not just a single thing.

im sorry, didnt see this part at all

C++ is case-sensitive. You must write "case".

ill stop buggin you, you seem really angry/ornery...

Sample code directed by CornedBee.

VB Code:

#include <iostream>
using namespace std;
int main(){
    int x; // declare x first
    cin>>x;
    switch(x){
        case 1: // case not Case
            cout<<"x = 1";
            break;
        case 2:
            cout<<"x = 2";
            break;
        case 3:
            cout<<"x = 3";
            break;
        default:
            cout<<"x = ";
            cout<<x; // not n coz we're dealing with x                                               
    }
    cout<<endl;
    return 0;
