ALUMNUS Placement Paper Pattern :
 
1. Find the locus of the point whose sum of distance from 2 fixed points is constant.

2. [-infinity to +infinity]integration(exp(-x*x))

3. The product of any 3 consecutive nos is always divisible by _ ? options[12/6/10/24]

4  int i=0,j=50
   while (i<j)
       {
       if(<some condtn>)
        {                                             
         <body of the loop>
         i++
        }
       elseif(<some condtn>)
       {  <body of the loop>
          j--
        }
      else(<some condtn>)
      {<body of the loop>
       j--
      }
      }

   How many times the body of the loopis going to be executed? options [unknown/25/50/depends on the given condtn]

5  How can you include a library code written in C++ in a source code written in C? (Options are there)
    Ans. Some cross-linked platform(compiler) is required for this.


6  int a[20],i
    for(i=0;i<20;i++)
     {
      a[i]=i;
     }                                              
      for(i=0;i<20;i++)
      {
       a[i]=a[20-i]
     }
     What is the final content of the program.

7   Which data structure should be used for searching an element in an array in constant time in case of average case?  
Ans. Hash table(not sure)


8   One question on ISO OSI model.easy one(not remembered)          

 9   Another question abt. a protocol
Ans. Token/Ring

10  If we want to connect two systems to form a network which leyer(OSI) is of most interest to us?
     Ans. Physical layer.

When compiled from command line what are linking options?

2   You have written a code in C++, and u have to use a C library , what would u do?
    (Ans: write extern "c" in header files)

3   Fiber optic backbone is in which OSI layer?


4   void main()
      {                                        
       int x=1;
       int y=1;
       int i;
       for(i=2;i<=100;i++)
        {
        x=x+i;y=y*(i+1)/(i-1);
        }
    What are the values of x & y?

5  If we carry out operation (-3)+(-6),then which of the what will be the value of carry and sign flag?

 6  void abc(int a[])
     {
      int k=0;int j=50;
      while(k<j)
     {
     if(a[i]>a[j])                                       
      k++;
      else
      j--;
     }
     How many times the loop will occur?


 7   Integrate e^(x^-2)dx , with limits -infinity to +infinity?What is the final value?

 8   Let p be a 16 bit number.The 2\'s complement of p will be represented by?

 9   void main()
       {
      int a[]={5,4,3,2,1};
      int x,y;
      int *p=&a[2];
      *p++;
      x=++*p;
      y=*(p++);
      printf("%d %d",x,y)\'
      }
     What will be the value of x and y?

     {
      a[i]=i;

     }
      for(i=0;i<20;i++)
     {
      a[i]=a[19-i];                                       
     }
