    Sample Test paper

    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?
