When i assign a non-zero value to a boolean variable, the output is true. And when i assign a non-zero value from the console, the output is false.
WHY?

Please take a look at the following codes:
#include <iostream.h>
#include <conio.h>

main()
{
bool bln;
cout<<"Enter value: ";
cin>>bln;

if (bln==true)
{
cout<<bln<<"TRUE";
}
else
{
cout<<bln<<"FALSE";
}
getch();
}

Output:
0FALSE


/*************************************...
#include <iostream.h>
#include <conio.h>

main()
{
bool bln=253;


if (bln==true)
{
cout<<bln<<"TRUE";
}
else
{
cout<<bln<<"FALSE";
}
getch();
}

Output:
1TRUE
