Unit-I
a)      Why study the programming languages? Give some effective reasons? [Marks 8]
b)      Explain the different language paradigms with suitable examples? [Marks 8]
OR
a)      Explain the organization of conventional computer with block diagram? [Marks 8]
b)      Explain the stages of translation i.e. in a compiler with following examples?
      Real A:=B+C*10;               [Marks 8]
Unit-II
       a)      Describe the example of an operation in a programming languages that: [Marks 8]
   i)                    Is implemented directly in hardware.
  ii)                   Is implemented as a subprogram.
  iii)                 Is implemented as a inline code sequence.
b)      Explain implementation of structure data type with following example:
             Char array[10];                  [Marks 8]
OR
a)      What are the different elements of specification of a elementary data types? Give general signature of specification of an operation. [marks 8]
b)      What are the arrays & variant records? How they differ from the conventional arrays and records. Explain with suitable example. [Marks 8]
Unit-III

a)      If (N>final val) {….}
Return (20*X+M(N)); }
Now explain the components of an activation of the subprogram which are needed at runtime. [Marks 8]
b)      Define the structured sequence control statements. Explain the conditional statements and its implementation with suitable example. [Marks 8]
OR
a)      Explain the difference between Emlicit and  Explicit sequence control. [Marks 4]
b)      Differentiate between unification & substitution. [Marks 4]
c)       What are the problems are occurs in evolution of tree representation of expression. [Marks 8]
Unit-IV

a)      Give a program fragment that produces different result under each of the following parameter passing techniques:  [Marks 8]
i)                    Call by value
ii)                   Call by reference
iii)                 Call by name.
b)      Explain the block structure with suitable example? [Marks 8]
OR

a)      Consider the following subprogram definition in Pascal:
Procedure SUB(X: integer);
Var Y: real;
                Z:array [1..3] of real;
Procedure SUB 2;
Begin
                …….
End {SUB 2}..;
Befing…….
                End {SUB};                                          [Marks 8]
b)      Explain the static and dynamic scope with suitable example? [Marks 8]
Unit-V
a)      Explain the heap storage management with
i)                    Fixed size storage management.
ii)                   Variable size storage management.         [Marks 8]
b)      What are the elements requiring in storage explain. [Marks 8]
