Question 3

What is the output of following code :

[sourcecode] #include using namespace std; int main() { try { throw 10; } catch (char *excp) { cout << "Caught " << excp; } catch (...) { cout << "Default Exception\\n"; } return 0; } [/sourcecode]

• Compiler Error
• Caught Default Exception
• Caught Integer Exception
• Default Exception

Question 4

• 5 4 2 3 1 0
• 0 1 3 2 4 5
• 5 0 1 2 3 4
• 5 0 4 1 2 3

Question 5

A student started studying Competitive programming from his senior and will study for 7 days. What is the minimum number of cuts he can have on gold bar so that his senior gets 1 unit of gold at the end of everyday as return.

• 7
• 2
• 3
• Not Possible

Question 6

• True
• False

Question 7

Time Complexity to find smallest element in Binary Max Heap?

• O(logN)
• O(N)
• O(N * logN)
• O(1)

Question 8

Given following three values, What is the total number of maximum chocolates you can eat ?

1. Total Money you have to buy chocolates = 50
2. Price of single chocolate = 3
3. Number of wrappers to be returned for getting one extra chocolate = 4

• 20
• 19
• 22
• 21

Question 9

Consider the procedure below for the Producer-Consumer problem which uses Semaphores and choose the correct statement:

C

semaphore n = 0;
semaphore s = 1;

// Producer Function
void producer(){
    while(true){
        produce();
        semWait(s);
        addToBuffer();
        semSignal(s);
        semSignal(n);
    }
}

C

// Consumer function
void consumer(){
    while(true){
        semWait(s);
        semWait(n);
        removeFromBuffer();
        semSignal(s);
        consume();
    }
}

• The producer will be able to add an item to the buffer, but the consumer can never consume it.
• The consumer will remove no more than one item from the buffer.
• Deadlock occurs if the consumer succeeds in acquiring semaphore s when the buffer is empty.
• The starting value for the semaphore n must be 1 and not 0 for deadlock-free operation.

Question 10

What is the output of following code?

C

#include <stdio.h>
      int main()
      {
             const int x;
             x = 10;
             printf(\"%d\", x);
      
        return 0;
       }

• Compiler Error
• 10
• 0
• Runtime Error
