Global variables

Question

#include <iostream>

using namespace std;

int x=15;
int main()
{
int x=10;
{
int x = 5;
cout<<::x;
}
return 0;
}

is there any way to print x=10 without changing variable names and position of cout?

Answer 1

Yes their one way to print 10 write cout<<x; after first cout before return 0 this will print 10
#include <iostream>

using namespace std;

int x=15;
int main()
{
int x=10;
{
int x = 5;
cout<<::x;
}
cout<<x;
return 0;
}

Try to define more variables in main function's primary block, even better, define various types of variables in primary block. Then try again : )

Answer 3

#include <iostream>

using namespace std;

int x=15;
int main()
{
int x=10;
{
int x = 5;
cout<<*((&x) + 1);
}
return 0;
}

But this could print x=10 in some compilers. If warnings are avoided.

Answer 4

Use a different variable name... Like y...
