Answer: a) int varName;
Explanation: In C#, the correct way to declare a variable is to specify its data type followed by the variable name. For example, “int” specifies the data type of the variable as an integer, and “varName” is the name of the variable.
Which of the following is not a primitive data type in C#?
a) int
b) char
c) string
d) double
Answer: c) string
Explanation: In C#, a string is not a primitive data type. It is a reference type that represents a sequence of characters.
What is the output of the following code in C#?
int a = 10;
int b = 5;
int c = a % b;
Console.WriteLine(c);
a) 2
b) 5
c) 0
d) 1
Answer: d) 0
Explanation: The “%” operator in C# is the modulo operator, which returns the remainder of dividing two numbers. In this example, the remainder of dividing 10 by 5 is 0, so the output will be 0.
Which of the following is not a control structure in C#?
a) if-else
b) while
c) do-while
d) class
Answer: d) class
Explanation: A class is not a control structure in C#. It is a fundamental programming construct used to define an object’s properties and methods.
Which of the following is a valid C# array declaration?
a) int[] arr = {1, 2, 3};
b) int arr[3] = {1, 2, 3};
c) int arr[] = new int[3] {1, 2, 3};
d) int arr[3] = new int[] {1, 2, 3};
Answer: a) int[] arr = {1, 2, 3};
Explanation: This is a valid C# array declaration. The curly braces are used to initialize the array’s elements without specifying the size of the array.
What is the output of the following code in C#?
int x = 10;
int y = 20;
bool result = (x > y);
Console.WriteLine(result);
a) true
b) false
c) 10
d) 20
Answer: b) false
Explanation: The comparison operator “>” is used to compare two values in C#. In this example, the value of “x” is not greater than the value of “y”, so the output will be false.
Which of the following is not a valid access modifier in C#?
a) public
b) private
c) protected
d) static
Answer: d) static
Explanation: Static is not an access modifier in C#. It is used to declare a member that belongs to a type itself rather than to a specific instance of that type.
What is the output of the following code in C#?
for (int i = 0; i < 5; i++) { Console.WriteLine(i); } a) 0 1 2 3 4 b) 1 2 3 4 5 c) 0 1 2 3 4 5 d) 1 2 3 4 Answer: a) 0 1 2 3 4 Explanation: The “for” loop is used to iterate through a block of code a specified number of times. In this example, the loop runs 5 times, and the variable “i” is incremented by 1 each time. So, the output will be the values of “i” from 0 to 4. What is the output of the following code in C#? int[] arr = {1, 2, 3}; Array.Reverse(arr); Console.WriteLine(arr[0]); a) 1 b) 2 c) 3 d) Compilation error Answer: c) 3 Explanation: The “Array.Reverse” method is used to reverse the order of elements in an array. In this example, the array “arr” is reversed, and the first element is 3. So, the output will be 3. Which of the following is not a valid way to declare a method in C#? a) public void methodName() b) static int methodName() c) private string methodName(string arg) d) methodName(string arg) Answer: d) methodName(string arg) Explanation: This is not a valid way to declare a method in C#. A method declaration should include the access modifier, return type (if any), method name, and parameters (if any). What is the output of the following code in C#? string str = “Hello World”; Console.WriteLine(str.Length); a) 11 b) 12 c) 10 d) Compilation error Answer: a) 11 Explanation: The “Length” property is used to get the number of characters in a string. In this example, the string “Hello World” has 11 characters, so the output will be 11. Which of the following is not a valid way to initialize a variable in C#? a) int x = 10; b) int y = new int(); c) int[] arr = {1, 2, 3}; d) int z; Answer: b) int y = new int(); Explanation: This is not a valid way to initialize a variable in C#. The “new” keyword is used to create a new instance of an object, but it cannot be used to initialize a variable of a primitive data type. What is the output of the following code in C#? int a = 10; int b = 5; int c = (a > b) ? a : b;
Console.WriteLine(c);
a) 5
b) 10
c) 15
d) Compilation error
Answer: b) 10
Explanation: The ternary operator “?” is used to simplify an “if-else” statement in C#. In this example, if “a” is greater than “b”, the value of “c” will be “a”, otherwise it will be “b”. Since “a” is greater than “b”, the output will be 10.
Which of the following is a valid way to declare a class in C#?
a) class ClassName
b) void ClassName
c) int ClassName
d) string ClassName
Answer: a) class ClassName
Explanation: The “class” keyword is used to declare a new class in C#. The class name should follow immediately after the keyword.
What is the output of the following code in C#?
int x = 10;
int y = 5;
if (x > y)
{
Console.WriteLine(“x is greater than y”);
}
else
{
Console.WriteLine(“y is greater than x”);
}
a) x is greater than y
b) y is greater than x
c) 10
d) 5
Answer:a) x is greater than y
Explanation: The “if-else” statement is used to conditionally execute a block of code in C#. In this example, the condition “x > y” is true, so the code inside the “if” block is executed, which outputs “x is greater than y”.
Which of the following is a valid way to create an object in C#?
a) ClassName obj = new ClassName();
b) obj ClassName = new ClassName();
c) ClassName obj = ClassName();
d) obj ClassName = ClassName();
Answer: a) ClassName obj = new ClassName();
Explanation: The “new” keyword is used to create a new instance of a class in C#. The class name should be followed by parentheses, and any constructor parameters (if any) should be passed inside the parentheses.
What is the output of the following code in C#?
for (int i = 0; i < 10; i++)
{
if (i == 5)
{
break;
}
Console.WriteLine(i);
}
a) 0 1 2 3 4 5
b) 0 1 2 3 4
c) 5
d) Compilation error
Answer: b) 0 1 2 3 4
Explanation: The “break” keyword is used to exit a loop in C#. In this example, the loop runs from 0 to 9, but when “i” is equal to 5, the “break” statement is executed, which exits the loop. So, the output will be the values of “i” from 0 to 4.
Which of the following is a valid way to declare a constant in C#?
a) const int x = 10;
b) int const x = 10;
c) int x = 10; readonly
d) int x = const 10;
Answer: a) const int x = 10;
Explanation: The “const” keyword is used to declare a constant in C#. The constant value should be assigned at the time of declaration and cannot be changed later.
What is the output of the following code in C#?
string str1 = “Hello”;
string str2 = “World”;
Console.WriteLine(str1 + ” ” + str2);
a) HelloWorld
b) Hello World
c) Hello+World
d) Compilation error
Answer: b) Hello World
Explanation: The “+” operator is used to concatenate two strings in C#. In this example, the two strings “Hello” and “World” are concatenated with a space in between, so the output will be “Hello World”.
Which of the following is not a valid access modifier in C#?
a) public
b) private
c) protected
d) static
Answer: d) static
Explanation: “Static” is not an access modifier in C#. It is used to declare a member of a class that can be accessed without creating an instance of the class. The access modifiers in C# are “public”, “private”, and “protected”.
