Company: Cisco Systems

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(“isn”);
} 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..then wat is de
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?????
