Sample Question Paper

1.What is diners phylosophers algorithm.
2.What is atomicity.Explain
3. Give an example of source- level debugger in unix/linx.
4. What is Pre-emptive multitasking.
5. Do not remember this one.

DataStructures

1. Where will the parameters be stored when a function is called in a program.
2. What is recursion?What are its disadvantages.
3. Which one is the best and efficient sort?

Networking

1. ASN.1 belongs to which layer.
2. Give an example of popular Transport Layer Protocol
3. What is the netmask of Class B IP address?
4. Explain CSMA/CD.
5. Given a size from 0-7 what would be the least window size.

C Language

1. main()
{
printf("%d",printf("HelloSoft"));
} Output?

2. case 1: case 2:
typedef Struct { typedef Struct {
int a; char p;
char b; int q;
int d; char k;
char e; int l;
}A; }A;
Assuming ‘packing’ is not enabled, which case will give an error of Sizeof(A) less.

3. main()
{
int i=3;
printf("%d %d %d",i++,i,++i);
}

4. main()
{
int i=10;
int j,k=5;
int a[10];
for(j=0;j<10;j++)
a[j]=(i+k)+(i*k);
}
Optimize the above code.

5. Write In Order Tree Traversal Pseudo-code.

6. main()
{
int *p=0x100;
int *q=0x100;
int k=p*q;
printf("%xn",k);
} Output ?

7. Char* foo(Str…) {
char str[4];
strcpy(str,"HelloSoft");
return str;
} Output?

8. int a[10][20][30][40];
int *p
How to access an element of a using p?

9. main()
{
int i=10;
if(i>20)
if(i==10)
print("Hi");
else
printf("Bye");
} Output ?

10. main()
{
float f;
int i;
//something like this not remember these 4 questionsexactly
f=(float *)malloc(sizeof((float *)*4));
}
