C + + line string processing

Sometimes programming needs to process a string of strings, including a row of spaces connected together. If you read the blanks directly with CIN, you will stop.

The practical approach is to use the Getline function with a stringstream flow operation, the simple code is as follows.

#include <iostream> #include <sstream> #include <string>using namespace Std;int main () {string str; while (Getline (CIN,STR)) {Cout<<endl;istringstream get (str); string Substring;while (get>>substring) { Cout<<substring<<endl;}} return 0;}

In the above program, you first use Getline to read a line of strings, and then use Istringstream get (str) to associate the read str with GET, and then you can loop the data from get to read. Very convenient.
