使用find 和replace 方法 这种方法不直接替换子串,而是先找到子串的位置,然后基于这个位置和子串的长度来替换。 cpp #include <iostream> #include <string> std::string replaceSubstring(std::string& source, const std::string&
replace(6, 3, "STL"); // "Hello STL World" size_t pos = s.find("STL"); if (pos != string::npos) { cout << "Found 'STL' at position: " << pos << endl; } string sub = s.substr(6, 3); // "STL" cout << "Substring: " << sub << endl; return 0; } ...
string_replace(strinfo, "Winter", "wende"); cout<<"After replace Winter with wende, the string is :\n"<<strinfo<<endl; return0; } string.erase(pos,srclen);//srclen是删除的长度 string.insert(pos,strdst); //pos是定位,strdst是插入的函数 voidstring_replace(string & strBig,conststring...
