Model Test Paper Computer Application (12th Class) Time: 3 hours Theory: 60 Marks Structure of Question Paper 1. There will be three sections of Question Paper (Part- A, Part- B, and Part- C). 2. In Part- A, there will be 3 Question from Question no. 1 to 3.  Question 1 will be of 8 (sub parts) Multiple choice type questions of one mark each.  Question 2 will be of 8 (sub parts) fill in the blanks type questions of one mark each.  Question 3 will be of 8 (sub parts) True/false or full form or shortcut key type questions of one mark each. 3. In Part -B, there will be 6 Questions from Question no 4 to 9, each question will be of 4 marks. 4. In Part –C, there will be 2 questions from Question no. 10 to 11, each question will be of 6 marks. 5. All questions of Part-A, Part-B, and Part-C are compulsory. However internal choice may be given in part-C. PART - A Q 1 Multiple Choice questions 1 x 8 =8 1. A software engineering concept, in which concepts are represented as "objects" is called . (a) Object Oriented (b) Class oriented (c) Concept oriented (d) None of these 1 2. Every program in C++ has function, which is always called when your program first executes. ( a) gets() (b) puts() (c) main() (d) None of these 1 3. Reserved words called in C++ have predefined meaning to compiler. (a) Functions (b) classes (c ) Keywords (d) Inheritance 1 4. A group of characters that logically belong together is called . (a) Tokens (b) functions (c ) Objects (d) classes 1 5. Reserved memory locations to store values is called (a) Class (b) variable (c ) Constant (d) Operator 1 6. A building block of a program is known as . (a) Statement (b) Expression (c ) Logic (d) Operator 1 7. symbol that tells the compiler to perform specific mathematical or logical manipulations.

(a) Operator (b) Symbol (c ) Operand (d) Statement 1 8. is used to alter the meaning of the base type so that it more precisely fits the needs of various situations. (a) Modifier (b) Conversion (c ) Identifier (d) Modular 1 Q 2 Fill in the blanks 1 x 8 =8 1. grants operations common to both input and output 1 2. C++ allows at least levels of nesting 1 3. A function is a that together perform a task. 1 4. Variables that are declared inside a function or block are . 1 5. If a function returns a value, it must have a statement that specifies the value to return. 1 6. The keyword makes variable value stable 1 7. An array as a of the same type. 1 8. An element in 2-dimensional array is accessed by using the 1 Q 3 True/ False 1 x 8 =8 1. Array subscript is the same as the index. 1 2. Array of strings in C++ is used to store a null terminated string which is not a character array. 1 3. Classes have no similarities with data structures. 1 4. An object is an instantiation of a class. 1 5. A static member function can only access static data member. 1 6. Member functions cannot be defined within the class definition. 1 7. Information must be relevant to basic purposes. 1 8. The connections (network links) between nodes cannot be established using wireless media. 1 PART –B 4 x 6 = 24 Q4 What is an Identifier?
