Well, I was using C++ language (from the Microsoft Visual Studio 2005) to create a simple console application as following: #include <iostream> using namespace std; int main() { int value = 0; statement_01: cout << "Type in any integer value: "; cin >> value; if(value != 1 || value != 2) cout << "The value in the variable 'value' is not 1 ou 2"; else goto statement_01; cout << endl << endl << endl; } When I run it it does not work correctly because it should repeat all these statements if I typed "1" ou "2" values. But when I type in these either these values it finishs. Can someone help me?!

Your program doesn't work correctly because Your IF is logically wrong.
Look...

when You type "1" then you have :

IF ( 1 !=1 || 1 !=2 )
-------|----------|-------
-----false--||---true


after that You have

IF ( false or(||) true )
false || true gives you true

after that
IF (true) ...

As we know the IF executes when in () is TRUE.

So the conclusion is : Change the logical operations as OrangyTang said.

greetz

It was my fault. Now it worked!!!
Thank you all!!! You two, OT and OrangyTang, were very useful and kind!!!
