2、）時間最短（2）費用最小（3）中轉(zhuǎn)次數(shù)最少，以使上述業(yè)務(wù)可以借助計算機來完成。2、要求：該程序所做的工作的是模擬全國交通咨詢，為旅客提供三種最優(yōu)決策的交通咨詢。此程序規(guī)定：（1） 在程序中輸入城市名稱時，需輸入10個字母以內(nèi)的字母串；輸入列車或飛機編號時需輸入一個整型數(shù)據(jù)；輸入列車或飛機的費用時需輸入一個實型數(shù)據(jù)；輸入列車或飛機開始時間和到達時間時均需輸入兩個整型數(shù)據(jù)（以hh：mm的形式）；在選擇功能時，應(yīng)輸入與所選功能對應(yīng)的一個整型數(shù)據(jù)。（2）程序的輸出信息主要是：最快需要多少時間才能到達，或最少需要多少旅費才能到達，或最少需要多少次中轉(zhuǎn)到達，并詳細說明依次于何時乘坐哪一趟列車或哪一次班機到

3、何地。（3）程序的功能包括：提供對城市信息的編輯，提供列車時刻表和飛機航班表的編輯，提供三種最優(yōu)決策：最快到達、最省錢到達、最少中轉(zhuǎn)次數(shù)到達。三、程序設(shè)計步驟全國交通咨詢模擬問題描述：處于不同目的的旅客對交通工具有不同的要求。例如，因公出差的旅客希望在旅途中的時間盡可能的短，出門旅游的游客則期望旅費盡可能省，而老年旅客則要求中轉(zhuǎn)次數(shù)最少。編制一個全國城市間的交通咨詢程序，為旅客提供兩種或三種最優(yōu)決策的交通咨詢。 #include#include #include #define err 0 #define ok 1 #define dij_maxn 33 #define max_vertex_
