Compilation Error?

[vikascoder]

Consider the following code snippet..

#include<iostream>
using namespace std;

int func(void);

int main() {
cout<<"Result :"<<func()<<endl;
}

int func (void) {
int result = 0;
if (true) {
result = 1;
goto cleaup:

}

int i = 0; // i initialize a dummy here.. Error in XCode or Gcc !

cleanup:
return (result);
}

If i compile the above code with Visual Studio 6.0 compiler or
CodeWarrior (Mac) it compiles without any error, but if i compile this
code using gcc or XCode (Mac) it gives the following error..
error: jump to label 'cleanup'
error: from here
error: crosses initialization of 'int i'

The only way to solve this problem is to move the 'int i' definition
below the 'int result' definition... is there any other way??

"It is possible to transfer into a block, but not in a way that
bypasses declarations with initialization. A program that jumps from a
point where a local variable with automatic storage duration is not in
scope to a point where it is in scope is ill-formed unless the variable
has POD type (3.9) and is declared without an initializer (8.5)."

Don't use goto?

I'm surprised this compiles with any compiler.

it shudnt have worked with any of the compiler as far as myknowledge is
concerned.. try the latest compiler version n u'll catch the error..
the only workout is : goto is a bad practice.. stop using it..
