An algorithm is a finite sequence of well-defined, computer-implementable instructions, typically to solve a class of specific problems or to perform a computation Algorithms are always unambiguous and are used as specifications for performing calculations, data processing, automated reasoning, and other tasks In contrast, a heuristic is a technique used in problem solving that uses practical methods and/or various estimates in order to produce solutions that may not be optimal but are sufficient given the circumstances An example about an algorithm 2) Represent a small and simple problem Firstly, I will introduce the C# language It used in algorithm to solved problem C# is a general object-oriented programming (OOP) language for networking and Web development C# is specified as a common language infrastructure (CLI) language In January 1999, Dutch software engineer Anders Hejlsberg formed a team to develop C# as a complement to Microsoft’s NET framework Initially, C# was developed as C-Like Object Oriented Language (Cool) The actual name was changed to avert potential trademark issues In January 2000, NET was released as C# Its NET framework promotes multiple Web technologies II Analyse the problem and design the solutions by the use of suitable methods 1) Analyse the problem There is a basic example about a problem that can solve by algorithm A teacher wants to manage grade of his class He asks you to help him to create a small application to manage them He needs to enter name, ID, grade of students Then he needs to print information and grade together After read clearly the scenario, I solved it by using an algorithm based on C# language to create a program must have full option that satisfy the requirement of teacher We need to create an application to enter name, score, ID 2) Flowchart Step 1: START Step 2: DECLARED the variable n, ID[], grade[], name[], flag Step 3: SET flag=false Step 4: Print menu Step 5: Input option in Step 6: If option=1 then Step 6.1: Call input() Step 6.2: SET flag=true Step 6: ELSE (flag=false) is true, return Step Step 7: IF option=2 then CALL showInfo() Step 8: WHILE option != 3, repeat Step Step9: STOP Main of application Step 1: START Step 2: PRINT (“Input total student (3-30) ”) Step 3: PRINT ("1 Input information") Step 4: PRINT ("2 Show information") Step 5: PRINT ("3 Exit") Step 6: PRINT (“Input your choice: “) Step 7: STOP Menu list of application Step 1: START Step 2: DECLARE the variable i Step 3: INPUT n; Step 4: WHILE n30 is true , return Step Step 6: SET i=0 Step 7: WHILE i
