21. Which API is used to draw a circle ?
(A) Circle ( )
(B) Ellipse ( )
(C) Round Rect ( )
(D) Pie ( )
Answer B
Explanation : In mathematics, an ellipse is a curve in a plane surrounding two focal points such that the sum of the distances to the two focal points is constant for every point on the curve. As such, it is a generalization of a circle.
22. In DML, RECONNCT command
cannot be used with
(A) OPTIONAL Set
(B) FIXED Set
(C) MANDATOR Set
(D) All of the above
Answer B
Explanation : The RECONNECT command can be used with both OPTIONAL and MANDATORY sets, but not with FIXED sets. The RECONNECT command moves a member record from one set instance to another set instance of the same set type. It cannot be used with FIXED sets because a member record cannot be moved from one set instance to another under the FIXED constraint.

11. In compiler design ‘reducing the strength’ refers to
(A) reducing the range of values of input variables.
(B) code optimization using cheaper machine instructions.
(C) reducing efficiency of program.
(D) None of the above
Answer : B
Explanation :I

n compiler design , strength reduction is a compiler optimization where expensive operations are replaced with equivalent but less expensive operations. The classic example of strength reduction converts "strong" multiplications inside a loop into "weaker" additions – something that frequently occurs in array addressing.

Most of a program's execution time is typically spent in a small section of code (called a hot spot), and that code is often inside a loop that is executed over and over.

A compiler uses methods to identify loops and recognize the characteristics of register values within those loops.

12. In which addressing mode, the effective address of the operand is generated by adding a constant value to the contents of register ?
(A) Absolute
(B) Indirect
(C) Immediate
(D) Index
Answer : D
