1. Explain the output of following program :
a) namespace xyz
{
int x = 10 ;
}
void main ( )
{
int y = 200 ; int x = 100 ;
cout <<endl << "x⇒ " << x;
using namespace xyz;
cout << endl<< "x⇒ " << x;
cout <<endl<< "y=" << y;
}
b) void main ( )
{
int a,* b = &a;
int * * c = &b;
a=2;
* * c = 4;
b = (int* ) * * c;
cout <<"A=" <<a<<endl;
cout <<"B=" <<b;
}
c) void main ( )
{
cout << set w (10) << setfill ('#');
cout.setf (ios :: internal, ios :: adjustfield);
cout <<setiosflags (ios :: showpoint);
cout << setprecision(5);
cout <<11.432 <<endl;
cout << setiosflags (ios :: showpos);
cout << 15.4;
}
d) void main ( )
{
b001 b1, b2;
b2 = true;
int a = 10, b = 20;
b1=a=b;
b001 b3 = b1 || b2;
if (b3)
cout << "good";
else
cout << "very good";
