Cisco Placement Paper 3

    Cisco test  Conducted on 17th sunday october at bangalore there were almost 40 technical questions and 10 analytical  questions..total 50 questions..

Analytical questions

1. find perimeter of a trapezium wit 3 sides given and distance b/w  parallel sides given...

2. A triangle ABC is given, a line DE is paralel to base side and that  cuts the triangle.. the ratio of area of triangle to the area of  trapezium .given DE/BC=3/5..

3. four concentric circles r given .the radius of 1st circle is x.next  is 2x,then 3x and 4x. given that area b/w 2nd and 1st is A and 4th  and 3rd circles being B.find ratio of A to B

4. difference b/w the perimeteres of two concentric circles is 66.find  the difference b/w radius..
   ans 10.5

5. 3/p=6,3/q=15......find p-q
   
   Technical questions.....
   

6. #define clrscr() 100
    main()
      {
      clrscr();
      printf("%d",clrscr());
     }  

7. which of the followin is used for avoidin network congestion
     bufferin 
     cachin 
     sourcequench
     all of de above

8. main()
    {
     int a;
     printf("%d",scanf(%d,&a));
   }
   wats o/p of this pgm..wat will b printed
   ans :0

9. main()
     {
      printf("as"); 
      printf("\bhi"); 
      printf("is\n");
     }  wat will b printed.

10. main()
      {
       unsigned short a=-1;
       unsigned char b=a;
       printf("%d %d ",a,b);
      }
      wat is o/p of the program
    a. 65535 -1
    b. 65535 65535
    c. -1 -1 

11. arrays base address is 1000....array is a[5][4]..then wat is de 
    correct address of a[4][3]...
    ans:1056

12. one packet is 64bytes..no of pkts send is 16000..then total no of  bytes send is 
    ans 1024000

13. #define maxval 5
    int main (void)
      {
       int i=1;
       if(i-maxval)
        {
         printf("inside");
         }
    else
       {
        printf("out"); 
       }
    find o/p???

14. #define a 3+3
    #define b 11-3
    main()
    {
      printf("%d",a*b);
    }
    wat is o/p?????

15. A question in which segment address is given ..logical address is  800..base addresses also given ..u hav 2 find physical address..

16. There was a question on processor speed in nanocycles..then it  performs a instruction in x cycles..dont remember

17. main()
     {
      int *i;
      int s=(int *)malloc(10*sizeof(int));
      for (i=0;i<10;i++)
       {
         printf("%d",i*i)
       }
    wats o/p
