[6/8 作業4] replace() 函式

試以 replace() 函式，將字串中的目標對象以特定字串(或字元)取代。
<string> 標頭檔所提供的 replace() 函式可將字串中特定位置及長度的字串，以另一個字串取代；而 <algorithm> 標頭檔所提供的 replace() 函式可將字串中所有的特定字元，以另一個字元取代。
  1. #include<iostream>
  2. #include<cstdlib>
  3. #include<string>
  4. #include<algorithm>
  5. using namespace std;
  6. int main()
  7. {
  8.     string str1="honolulu";
  9.     cout<<str1.replace(1,3,"a")<<endl;  //halulu

  11.     string str2="honolulu";
  12.     cout<<str2.replace(str2.find("u"),1,"a")<<endl;  //honolalu

  14.     string str3="honolulu";
  15.     replace(str3.begin(),str3.end(),'u','a');
  16.     cout<<str3<<endl;     //honolala

  18.     system("pause");
  19.     return 0;
  20. }
