Often encountered some big integer calculation problem, the calculation of integers without method using mon 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(xué)院計(jì)算機(jī)科學(xué)系 課程設(shè)計(jì)報(bào)告目錄第一章 緒論 .................................................................................................................................................1 課題背景 ......................................................................................................................................................1 課題簡(jiǎn)介 ......................................................................................................................................................1 編寫目的 ......................................................................................................................................................1 課程意義 ......................................................................................................................................................1第二章 設(shè)計(jì)簡(jiǎn)介及設(shè)計(jì)方案論述 ...............................................................................................2 程序分析 ......................................................................................................................................................2 程序設(shè)計(jì) ......................................................................................................................................................2 數(shù)據(jù)的接收與存儲(chǔ) .............................................................................................................................2 計(jì)算結(jié)果位數(shù)的確定 ........................................................................................................................2 進(jìn)位處理和借位
