exit(0);4：調(diào)試分析調(diào)試過程中，會有很多的錯誤。語句和函數(shù)的運用不到位，還存在許多的小錯誤。5：測試結(jié)果 通過我想同學(xué)求助，向老師咨詢，查找書籍，在網(wǎng)絡(luò)上查找，最終使得程序順利運行。1：歡迎界面2：密碼輸入3：系統(tǒng)菜單選擇界面4：商品信息錄入及保存5：商品信息的修改6：商品信息的刪除及剩余物品記錄7：物品信息的查詢8：商品信息輸出9：系統(tǒng)環(huán)境顏色的選擇10：退出系統(tǒng) 課程設(shè)計總結(jié)上學(xué)期學(xué)習(xí)了C語言，所以對于C語言有了初步和基礎(chǔ)的認(rèn)識。這次做程序設(shè)計，許多的程序過程都是通過咨詢老師，同學(xué)，查詢網(wǎng)絡(luò)，查找書籍做的。感到自己的C語言知識還是很欠缺。程序中許多都是自己設(shè)計的簡單的語句，很少有精彩的部分，但是很知足，畢竟是自己第一次做，感覺挺好。但是總結(jié)下來，自己可是漏洞百出。通過一周多的實習(xí)設(shè)計，使我對于C語言有了更深刻，更多的了解，也是我認(rèn)識到C語言的難度，但是，我又感覺到了這門課程的樂趣，看著自己的成果一天天出現(xiàn)，那種喜悅是不可言語的。過程中，我發(fā)現(xiàn)自己的基礎(chǔ)知識薄弱，英語很多不認(rèn)識，知識做的過程中還要上查詢英語方面的知識，很是費事。還有就是有些概念很模糊，但是通過這次實習(xí)，我對于C語言有了新的認(rèn)識。在這一周時間里，經(jīng)過不斷的與同學(xué)和老師的討論，是我的C語言水平有了很大的提高。此次我還感覺到，C語言是一門實用性很強的課程。其實真正的程序過程就是頭文件，主函數(shù)，模塊函數(shù)。這些東西的組合才構(gòu)成了一個完整的函數(shù)體系。雖然說只有這幾項，但是就是這簡單的幾項，在一起通過邏輯，順序，等關(guān)系羅列開來，構(gòu)成了復(fù)雜的函數(shù)體。我就是在程序作業(yè)工程中老是在各種邏輯順序中迷糊，所以浪費了很長時間。這次的實驗設(shè)計，讓我對C語言有了很大的興趣。我相信我還會去自學(xué)的，因為我知道只是一門可以武裝子的課程。相信，通過這次的學(xué)習(xí)，還有以后的學(xué)習(xí)，會是我的C語言有很大的提高。 源程序#include <stdio.h> #include <stdlib.h>#include <conio.h>#include <string.h>#define COUNT 30 /*聲明商品的種類為30中*/#define N 30void start();
