replace() 函式

試以 replace() 函式，將字串中的目標對象以特定字串取代。
<string> 標頭檔與 <algorithm> 標頭檔皆有提供 replace() 函式，但其用法與效果略有不同。

#include<iostream>
#include<cstdlib>
#include<string>
#include<algorithm>
using namespace std;
int main()
{
string str1="honolulu";
cout<<str1.replace(5,1,"a")<<endl; //honolalu
string str2="honolulu";
cout<<str2.replace(str2.find("u"),1,"a")<<endl; //honolalu
string str3="honolulu";
replace(str3.begin(),str3.end(),'u','a');
cout<<str3<<endl; //honolala
system("pause");
return 0;
}
