【正文】 microputers directly by the integer programming language is existing types of storage and calculation, this research work to bring a barrier. So long integer solutions for the storage and operation, I put forward its own design solutions, using string array of long integers, store, the processing with numerical instead, because the string string length, and not just in each character strings can be one of the corresponding ultralong integer number, the long integers, add, subtract, multiply and divide into a string of add, subtract, multiply and divide. Use of long integer array stores. The advantages of puting is easier.After the design, this paper realized the long integer data storage and operation procedures, and analyses the testing system, various performance can achieve the desired level. Based on this program at the end of the detailed presentation.Keywords： long integer；string；array西安文理學院計算機科學系 課程設計報告目錄第一章 緒論 .................................................................................................................................................1 課題背景 ......................................................................................................................................................1 課題簡介 ......................................................................................................................................................1 編寫目的 ......................................................................................................................................................1 課程意義 ......................................................................................................................................................1第二章 設計簡介及設計方案論述 ...............................................................................................2 程序分析 ......................................................................................................................................................2 程序設計 ......................................................................................................................................................2 數(shù)據(jù)的接收與存儲 .............................................................................................................................2 計算結(jié)果位數(shù)的確定 ........................................................................................................................2 進位處理和借位處理 ........................................................................................................................3 商和余數(shù)的求法 ................................................................................................................................4第三章 詳細設計 ......................................................................................................................................5 超長整型數(shù)據(jù)的接收與存儲 ....................................................................................................................5 超長整數(shù)加法運算 .....................................................................................................................................5 超長整數(shù)減法運算 .....................................................................................................................................6 超長整數(shù)乘法運算 .....................................................................................................................................6 超長整數(shù)的整除、求余運算 ....................................................................................................................7第四章 設計結(jié)果及分析 ...................................................................................................................10 基本界面 ....................................................................................................................................................10 運行過程 ....................................................................................................................................................10 數(shù)據(jù)存儲運算范圍 ....................................................................................................................................10總 結(jié) ...
