编程题25：正整数转换为罗马数字公开课教案教学设计课件资料.docx

编写一个函数，将一个正整数转换为罗马数字。例如，输入数字4,输出字符串“IV”。usingSystem;usingSystem.Collections.Generic;classProgram(staticstringIntToRoman(intnum)(Dictionary<int,string>romanDict=newDictionary<int,string>0(1000,"M",900,"CM",500,D")l400,"CD",100,"C"),90,XC",50,"L",40,"XL",10,"X"),9,"IX"lS,"V"),4,"IV"LLTstringromanNumber=",;foreach(varpairinromanDict)(while(num>=pair.Key)(romanNumber+=pair.Value;num-=pair.Key;)returnromanNumber;)staticvoidMainO(intnum=4;stringromanNumber=IntTRoman(num);Console.WriteLine("TheRomannumeralrepresentationof0is1",num,romanNumber);)这些题目旨在考察你对C#编程语言的深入理解。它们涵盖了字符串处理、递归、字典等不同的概念。希望对你有帮助！如果你需要更多的题目或者有其他问题，请随时告诉我。
