字串處理 (一)

我們在宣告字串的時候要注意它的長度,以免位數不夠造成程式錯誤。事實上,每個字串後面都有一個 '\0' 的字元,例如 "tw" 字串,事實上總共用了 3 Bytes,若為中文字,則每個字要佔兩個字元。
例如:
char str[3]="tw";
char str[9]="字串處理";
//字串處理 (4種方式)
#include<iostream>
#include<cstdlib>
using namespace std;
int main()
{
string str1="Hello! My name is Tony!";
cout<<str1<<endl;
char str2[7]={"Hello!"};
cout<<str2<<endl;
char str3[6]={'H','e','l','l','o','!'};
for(int i=0; i<=5; i++)
cout<<str3[i];
cout<<endl;
string str4[5]={"Hello! ","My ","name ","is ","Tony!"};
for(int i=0; i<=4; i++)
cout<<str4[i];
cout<<endl;
system("pause");
return 0;
}
