1 : Predict and write output for the following code.
using System;
namespace DecisionMaking
{
class Program
{
static void Main(string[] args)
{
/* local variable definition */
int a = 10;
/* check the boolean condition using if statement */
if (a < 20)
{
/* if condition is true then print the following */
Console.WriteLine("a is less than 20");
}
Console.WriteLine("value of a is : {0}", a);
Console.ReadLine();
}
}
}
2 : Write missing statement to get the desired output.
using System;
namespace DecisionMaking
{
class Program
{
static void Main(string[] args)
{
/* local variable definition */
int a = 100;
/* check the boolean condition */
if (a < 20)
{
/* if condition is true then print the following */
Console.WriteLine("a is less than 20");
}
else
{
/* if condition is false then print the following */
//………………………………Missing statement-1……………………………….//
}
//………………………………Missing statement-2……………………………….//
Console.ReadLine();
}
}
}
Output
a is not less than 20
value of a is : 100
3 : Correct the following code and write output for the corrected code.
using System;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
char firstName = "John";
char lastName = "Doe";
Console.WriteLine("Name: " + firstName + " " + lastName);
Console.WriteLine("Please enter a new first name:")
firstName = Console.ReadLine();
Console.WriteLine("New name: " firstName " " lastName);
Console.ReadLine();
}
}
}
4 : Input two number A and B. perform different operations using different operators and different data types available in C#. (Note : Follow all the operators and data types to do above task. Use Online help whenever necessary.)
5 : Rearrange the given code to correct the program. The resultant program will be to enter 5 elements into an array and print sum of these elements.
using System;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
for (int i = 0; i < 5; i++)
{
string str = Console.ReadLine();
}
for (int i = 0; i < 5; i++)
{
sum = sum + arr[i];
}
Console.WriteLine("Sum of Elements : {0}",sum);
int[] arr = new int[5];
int sum = 0;
arr[i] = Convert.ToInt32(str);
Console.Write("Enter Element {0}: ", i);
Console.Read();
}
}
}
Output:
Enter Element 0: 1
Enter Element 1: 2
Enter Element 2: 3
Enter Element 3: 4
Enter Element 4: 5
Sum of Elements : 15
6: Write missing statement to get the desired output.
using System;
public class Hello3
{
public static void Main(string[] args)
{
Console.WriteLine("Hello, World!");
Console.WriteLine("You entered the following {0} command line arguments:",
args.Length );
//………………………………Missing statement-1……………………………….//
//………………………………Missing statement-2……………………………….//
//………………………………Missing statement-3……………………………….//
//………………………………Missing statement-4……………………………….//
}
}
Output:
-------------------
Hello, World!
You entered the following 4 command line arguments:
A
B
C
D
7 : Predict and write the output of the given code.
using System;
namespace CalculatorApplication
{
class NumberManipulator
{
public void swap(ref int x, ref int y)
{
int temp;
temp = x; /* save the value of x */
x = y; /* put y into x */
y = temp; /* put temp into y */
}
}
class TestRef
{
static void Main(string[] args)
{
NumberManipulator n = new NumberManipulator();
/* local variable definition */
int a = 100;
int b = 200;
Console.WriteLine("Before swap, value of a : {0}", a);
Console.WriteLine("Before swap, value of b : {0}", b);
/* calling a function to swap the values */
n.swap(ref a, ref b);
Console.WriteLine("After swap, value of a : {0}", a);
Console.WriteLine("After swap, value of b : {0}", b);
Console.ReadLine();
}
}
}
8 : Find out error code and correct it. Write the output of the corrected code.
using System;
namespace CalculatorApplication
{
class NumberManipulator
{
public int getValues(out int x, out int y, out int z )
{
Console.WriteLine("Enter the first value: ");
x = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("Enter the second value: ");
y = Convert.ToInt32(Console.ReadLine());
sum = “x” + “y” + “z”;
return “sum”;
}
}
class TestOut
{
static void Main(string[] args)
{
NumberManipulator n = new NumberManipulator();
/* local variable definition */
int a , b, c, sum;
/* calling a function to get the values */
sum = n.getValues(out a, out b, out c);
Console.WriteLine("After method call, value of a : {0}", a);
Console.WriteLine("After method call, value of b : {0}", b);
Console.WriteLine("After method call, value of c : {0}", c);
Console.WriteLine("Sum : {0}", );
}
}
}
9 : Given an array A containing 2*N+2 positive numbers, out of which 2*N numbers exist in pairs whereas the other two number occur exactly once and are distinct. Find the other two numbers.
Example 1:Input:
N = 2
arr[] = {1, 2, 3, 2, 1, 4}
Output:
3 4
Explanation:
3 and 4 occur exactly once.
Example 2:
Input:
N = 1
arr[] = {2, 1, 3, 2}
Output:
1 3
Explanation:
1 3 occur exactly once.
10: Given a matrix mat[][] of size N x M, where every row and column is sorted in increasing order, and a number X is given. The task is to find whether element X is present in the matrix or not.
Example 1:
Input:
N = 3, M = 3
mat[][] = 3 30 38
44 52 54
57 60 69
X = 62
Output:
0
Explanation:
62 is not present in the
matrix, so output is 0
Example 2:
Input:
N = 1, M = 6
mat[][] = 18 21 27 38 55 67
X = 55
Output:
1
Explanation:
55 is present in the
matrix at 5th cell.
Your Task:
You don't need to read input or print anything. You just have to complete the function matSearch() which takes a 2D matrix mat[][], its dimensions N and M and integer X as inputs and returns 1 if the element X is present in the matrix and 0 otherwise.
Expected Time Complexity: O(N+M).
Expected Auxiliary Space: O(1).
Constraints:
1 <= N, M <= 1005
1 <= mat[][] <= 10000000
1<= X <= 10000000
11: Write a program to find the sum of N elements of an Array.
12: Write a program to find the element from an Array and print 1 if element is found else print 0.
13. Write a Program that will accept the amount and find how many minimum
no of notes you required for that.
(Using the rupee notes of 1, 2, 5, 10, 20, 50, 100, 200, 500, 2000)
Input: 5748
Output:
Notes of Rs.2000 = 2 Notes of Rs.500 = 3 Notes of Rs.200 = 1
Notes of Rs.20 = 2 Notes of Rs.10 = 0 Notes of Rs.5 = 1
Notes of Rs.2 = 1 Notes of Rs.1 = 1
14. Write a Program to find the eligibility of admission for a professional course
based on the following criteria:
Marks in Maths >=65
Marks in Phy >=55
Marks in Chem>=50 and
Total in all three subject >=180 or
Total in Math and Physics >=140
INPUT:
Input the marks obtained in Maths :72
Input the marks obtained in Physics :65
Input the marks obtained in Chemistry :51
OUTPUT:
The candidate is eligible for admission.
15.Write a Program which accepts name from the user and prints the same
INPUT : R K University
OUTPUT: R K University
