• What will be the output of the C#.NET code snippet given below? int a = 10, b = 20, c = 30; int res = a < b? a < c? c : a : b; Console.WriteLine(res);
• Which of the following statements are correct? The conditional operator (?:) returns one of two values depending on the value of a Boolean expression. The as operator in C#.NET is used to perform conversions between compatible reference types. The &* operator is also used to declare pointer types and to dereference pointers. The -> operator combines pointer dereferencing and member access. In addition to being used to specify the order of operations in an expression, brackets [ ] are used to specify casts or type conversions.

• Which of the following statements is correct about Bitwise ^ operator used in C#.NET?
• Which of the following are NOT Relational operators in C#.NET? >= != Not <= <>=
• What will be the output of the C#.NET code snippet given below? int num = 1, z = 5; if (!(num <= 0)) Console.WriteLine( ++num + z++ + " " + ++z ); else Console.WriteLine( --num + z-- + " " + --z );
• Which of the following is NOT a Bitwise operator in C#.NET?
• Which of the following is NOT an Assignment operator in C#.NET?
• Suppose n is a variable of the type Byte and we wish to put OFF its fourth bit (from right) without disturbing any other bits. Which of the following statements will do this correctly?
• Which of the following are the correct ways to increment the value of variable a by 1? ++a++; a += 1; a ++ 1; a = a +1; a = +1;
• Suppose n is a variable of the type Byte and we wish, to check whether its fourth bit (from right) is ON or OFF. Which of the following statements will do this correctly?
• What will be the output of the C#.NET code snippet given below? byte b1 = 0xF7; byte b2 = 0xAB; byte temp; temp = (byte)(b1 & b2); Console.Write (temp + " "); temp = (byte)(b1^b2); Console.WriteLine(temp);
• Which of the following are Logical operators in C#.NET? && || ! Xor %
• Which of the following statements are correct about the following code snippet? int a = 10; int b = 20; bool c; c = !(a > b); There is no error in the code snippet. An error will be reported since ! can work only with an int. A value 1 will be assigned to c. A value True will be assigned to c. A value False will be assigned to c.
• Which of the following statements are correct about the Bitwise & operator used in C#.NET? The & operator can be used to Invert a bit. The & operator can be used to put ON a bit. The & operator can be used to put OFF a bit. The & operator can be used to check whether a bit is ON. The & operator can be used to check whether a bit is OFF.
• What will be the output of the C#.NET code snippet given below? byte b1 = 0xAB; byte b2 = 0x99; byte temp; temp = (byte)~b2; Console.Write(temp + " "); temp = (byte)(b1 << b2); Console.Write (temp + " "); temp = (byte) (b2 >> 2); Console.WriteLine(temp);
• Which of the following statements is correct about the C#.NET code snippet given below? int d; d = Convert.ToInt32( !(30 < 20) );
