C++ examples for STL:string
Insert into string by using the iterator version of insert()
#include <iostream> #include <string> #include <cctype> #include <algorithm> #include <vector> using namespace std; int main()//from w ww. j a va 2s.c o m { string strA("This is a test. another test test test"); // Create an iterator to a string. string::iterator itr; // Insert into a string via an iterator. // use find() algorithm to obtain an iterator to the start of the first 'a'. itr = find(strA.begin(), strA.end(), 'a'); // Next, increment the iterator so that it points to the character after 'a', which in this case is a space. ++itr; // Insert into str by using the iterator version of insert(). cout <<"Insert into a string via an iterator.\n"; string strB(" bigger"); strA.insert(itr, strB.begin(), strB.end()); cout << strA << "\n\n"; return 0; }
