2、供鍵盤式選擇菜單實現(xiàn)功能選擇。三、總體設(shè)計根據(jù)需求分析，可以將系統(tǒng)分為五大模塊：制卡、發(fā)卡、登陸、報表、積分。四、詳細設(shè)計1、主函數(shù)目的在于系統(tǒng)執(zhí)行將 main() 函數(shù)體內(nèi)的界面選擇部分語句單獨抽取出來作為一獨立函數(shù)，目的在于系統(tǒng)執(zhí)行 完每部分功能模塊后能夠方便返回到系統(tǒng)界面。void menu() int v,w1;doprintf("tt*MENU*nn");printf("tttt 1.card-maden");printf("tttt 2.card-lifen");printf("tttt 3.card-enter
