                                              TH
                              CLASS: 6

                                   1.  …Machine….language is the only language that a computer can 
                                        understand. 
                                   2.  …..Compiler…..translates a program at once and generates a list of 
                                        errors, if any. 
                                   3.  Value of a……..Variable…..can change throughout the program. 
                                   4.  An operator is applied on one or more……Operands…. 
                                   5.  A pseudo code must start with the keyword….begin…. 
                               D. ANSWER THE FOLLOWING QUESTIONS: 
                                    1.  List the name of 4 generations of computer programming 
                                         languages. 
                                         Ans- 1. Ist generation Machine language 
                                                      nd
                                                  2. 2   generation Assembly language  
                                                     rd
                                                3. 3  generation High level language 
                                                     th
                                                4. 4  generation Modern language 
                                    2.  How a program is different from a pseudo code? 
                                         Ans- Program is a set of instructions which tells the computer what to 
                                         do. 
                                         Pseudo code is an artificial code to understand program flow. 
                                    3.  What do you mean by data, data type, and variable? 
                                         Ans- Data is divided into three parts: 
                                              1.  Numbers(0-9) 
                                              2.  Alphabets(A-Z, a-z) 
                                              3.  Special symbols(+,-,<,>,=,etc) 
                                              Data type in programming language is asset of data with values 
                                              having predefined characteristics. For example, integers, float, 
                                              character & string. 
                                              Variable is a named storage location which is used to store the 
                                              values. Its value can be changed throughout the program. 
                                    4.  Explain NOT operator with suitable example. 
                                         Ans- Not (!) It returns the opposite Boolean value of its evaluating 
                                         operand .e.g.  
                                         Not (7==5)//evaluate to true because (7==5) would be false 
                                         Not (5>4)//evaluate to false because (5>4) would be true. 
                                         Not true// evaluate to false 
                                         Not false// evaluate to true 
               
            5.  List the steps required in planning of a program. 
              Ans-     1. Define the output & data flows. 
                            2. Develop the logic to get to that output 
                            3. Write the program. 
                                   
                                  OR 
               
                         1. Design a solution. 
                       2. Draw a flow chart. 
                       3. Write pseudo code. 
                      4. Write code. 
                      5. Test & debug 
                      6. Test with real world users 
                      7. Release program
