The definitions in an XML document are said to be __________ when the tagging system and definitions in the DTD are all in compliance.

Consider the JavaScript Code :
var y= "12";
function f( ) {
var y="6";
alert (this.y);
function g( ) {alert (y); }
g( );
}
f( );
If M is the number of alert dialog boxes generated by this JavaScript code and D1, D2, ...., DM represents the content displayed in each of the M dialog boxes, then :

What is the output of the following JAVA program?
class simple
{
public static void main(String[ ] args)
{
simple obj = new simple( );
obj.start( );
}
void start( )
{
long [ ] P= {3, 4, 5};
long [ ] Q= method (P);
System.out.print (P[0] + P[1] + P[2]+":");
System.out.print (Q[0] + Q[1] + Q[2]);
}
long [ ] method (long [ ] R)
{
R [1]=7;
return R;
}
} //end of class

What is the output of the following 'C' program? (Assuming little - endian representation of multi-byte data in which Least Significant Byte (LSB) is stored at the lowest memory address.)
#include
#include
/* Assume short int occupies two bytes of storage */
int main ( )
{
union saving
{
short int one;
char two[2];
};
union saving m;
m.two [0] = 5;
m.two [1] = 2;
printf("%d, %d, %d\n", m.two [0], m.two [1], m.one);
}/* end of main */

Given below are three implementations of the swap( ) function in C++ :
Which of these would actually swap the contents of the two integer variables p and q?

In Java, which of the following statements is/are True?
S1 : The 'final' keyword applied to a class definition prevents the class from being extended through derivation.
S2 : A class can only inherit one class but can implement multiple interfaces.
S3 : Java permits a class to replace the implementation of a method that it has inherited. It is called method overloading.
Code :
