C++字符串数组

字符串数组的使用：

1. 字符串数组的定义: 指针 + 一维数组：const char* season[] = { "Spring", "Summer",  "Fall", "Winter" }。season中每个元素都是一个指针。

2. 调用字符串数组中的每一个字符。season[0] = "Spring";

// chapter7.8.cpp : Defines the entry point for the console application.//#include "stdafx.h"#include <iostream>using namespace std;// 定义字符串数组(* array[], 指针加一维数组)const int num = 4;const char* season[num] = { "Spring", "summer", "Fall", "Winter" };struct Expense{double expense[num];};void fill_array(Expense& e, const int n) {for (int i = 0; i < n; i++) {// 字符串数组的使用, 如何调用字符串数组中的一个字符串cout << "Enter " << season[i] << " expense:" << endl;cin >> e.expense[i];}}void show_array(const Expense e, const int n) {for (int i = 0; i < n; i++) {cout << season[i] << ":\t";cout << e.expense[i] << endl;}}int _tmain(int argc, _TCHAR* argv[]) {Expense exp = { { 0 } };fill_array(exp, num);show_array(exp, num);return 0;}

// lesson5.20.cpp : Defines the entry point for the console application.// 二位数组的几种形式#include "stdafx.h"#include <iostream>using namespace std;const int Cities = 5;const int Years = 4;int _tmain(int argc, _TCHAR* argv[]) {// 字符串数组const char* cities[Cities] = {"Gribble City","Gribbletown","New Gribble","San Gribble","Gribble vista"};int maxTemperature[Years][Cities] = {{ 96, 100, 87, 101, 105 },{ 96, 98, 91, 107, 104 },{ 97, 101, 93, 108, 107 },{ 98, 103, 95, 109, 108 } };cout << "Maximum temperature for 2008-2011:" << endl;for (int i = 0; i < Cities; i++) {cout << cities[i] << ":\t";for (int j = 0; j < Years; j++) {cout << maxTemperature[j][i] << "\t";}cout << endl;}return 0;}
