Ittiam Written Test Questions

Round 1(30 mins): Written Test It was a written round (pen-paper). It started just after the company’s ppt (pre-placement talk). There were a total of 20 Mcqs (with negative marking), 10 from quantitative aptitude and 10 from technical aptitude to be solved in 30 mins. Quant questions were from time&work, speed-distance(tricky one), few maths quesns viz. related to area of circle, mathematical reasoning (like questions on propositional logic, there exists and for all ->these type of questions can be found in discrete mathematics). Overall it was of average difficulty level. 1) What is the return value of count when the function start() is called with num value of 2017 in the following program:

CPP

int start(int num) {
    int count = 0;
    while (num > 0) {
        ++count;
        num = (num - 1) & num;
    }
    return count;
}

Java

    public static int start(int num) {
        int count = 0;
        while (num > 0) {
            ++count;
            num = (num - 1) & num;
        }
        return count;
    }

Python3

def start(num):
    count = 0
    while num > 0:
        count += 1
        num = (num - 1) & num
    return count

JavaScript

function start(num) {
    let count = 0;
    while (num > 0) {
        count++;
        num = (num - 1) & num;
    }
    return count;
}

a)25 b)1 c)7 d)8 Ans) c 2)Global Variables can be shared between : a)Between both two process and two threads b)By processes only but not between Threads c)By Threads only but not between processes d)By neither processes nor threads Ans) c 3)You have 3 baskets, one with apples, one with oranges and one with both apples and oranges mixed. Each basket is closed and is labeled with ‘Apples’, ‘Oranges’ and ‘Apples and Oranges’. However, each of these labels is always placed incorrectly. How many fruits would you pick only one fruit from a basket to place the labels correctly on all the baskets? a)3 b)1 c)4 d)2 Ans) d 4)

C++

#include <iostream>

int main() {
    // Declare and initialize variables
    int x = 10;
    int y = 0;

    // While loop to decrement x and increment y until x becomes 0
    while (x > 0) {
        x--;  // Decrement x by 1
        y++;  // Increment y by 1
    }

    // Print the final value of y
    std::cout << y << std::endl;

    return 0;
}

C

#include <stdio.h>

int main(void) {
    unsigned int x = 10;
    unsigned int y = 0;
    while (x > 0) {
        --x;
        ++y;
    }
    printf("%u", y);
    return 0;
}

Java

public class Main {
    public static void main(String[] args) {
        int x = 10;
        int y = 0;
        while (x > 0) {
            x--;
            y++;
        }
        System.out.printf("%d", y);
    }
}

Python3

x = 10
y = 0

while x > 0:
  x -= 1
  y += 1

print(y)

JavaScript

// JavaScript equivalent of the Java code

// Declare and initialize variables
let x = 10;
let y = 0;

// While loop to decrement x and increment y until x becomes 0
while (x > 0) {
    x--;  // Decrement x by 1
    y++;  // Increment y by 1
}

// Print the final value of y
console.log(y);

Output

10
