Keywords and indentation are used to signify particular control structures C. Each set of instructions is written from top to bottom, with only one entry and one exit D. Try to keep each instruction/step as short as possible 6. What is an example of the information-receiving operation of a computer? A. Read (information from a file) B. Write (information to a file) C. Use actual mathematical symbols or the words for the symbols (+, -, *, /) D. Giving data an initial value: Initialize, Set
- 2. 7. Please select one item which is not a guide when writing pseudo code A. Keywords are written in CAPITALS B. Structural elements might come separately C. Indenting is used to show structure in the algorithm D. The names of subprograms are underlined 8. What can we do with the Circle symbol when drawing the flowchart to represent the algorithm? A. Use it to represent an event which occurs automatically. Such an event will trigger a subsequent action, for example `receive telephone call’, or describe a new state of affairs. B. Use it to represent an event which is controlled within the process. Typically this will be a step or action which is taken. In most flowcharts this will be the most frequently used symbol C. Use it to represent a decision point in the process. Typically, the statement in the symbol will require a `yes' or `no' response and branch to different parts of the flowchart accordingly D. Use it to represent a point at which the flowchart connects with another process. The name or reference for the other process should appear within the symbol 9. Please select the best variable name for an employee's last name A. empLastName B. lastNameOfTheEmployeeInQuestion. C. emplastname D. empLstNm 10. Which structure theorem is used n a computer program or algorithm to determine which particular step or set of steps is to be executed? A. Sequence B. Selection C. Repetition D. Subprogram 11. What is incorrect function of the parameter using in communicating between modules? A. To pass information from a calling module to a subordinate module B. To pass information from a subordinate module to its calling module C. To fulfil a two-way communication role D. To store the reference data 12. In below definitions on the global data, which one is incorrect? A. Data that can be used by all the modules in a program B. Every module in the program can access and change data C. Variables which are defined within the sub module D. Lifetime of a global variable spans the execution of the whole program 13. Please choose correct definition of the module parameters A. Reference parameters pass a copy of the value of a parameter from one module to another B. Value parameter pass the memory address of a parameter from one module to another
- 3. C. Formal parameters are the one that appear when a submodule is defined D. Variables and expressions that are passed to a submodule in a particular call are called formal parameters 14.

What type of coupling if “Modules pass data structures but only use part of them.”? A. Content Coupling B. Common Coupling C. Control Coupling D. Stamp Coupling 20. What type of coupling when “Modules communicate only through data which is used”? A. Common Coupling B. Control Coupling C. Stamp Coupling D. Data Coupling 21.
