THIS PAPER CONSISTS 6 PARTS. all are multiple choice q's 

1 general
2 c/unix
3 c++/motif 
4 database 
5 x-windows
6 ms-windows
we have written q's not acc. to each part.total 50. q's. time is sufficient. if u have basic idea about all of the u can easily answer the questions.

2. #include<iostream.h>
main()
{
printf("Hello World");

swap(x,y);
}
after calling swap ,what are yhe values x&y?

}
struct derv2 : base 
{int a,e;
}
base::base()
{
a=2;b=3;
}
derv1::derv1(){
b=5;
c=10;d=11;}
base::function1() 
{return(100);
}
derv1::function1() 
{
return(200);
