stringstream string to int

Question

The C++ code below does int to string and a string to int conversions. Then, it repeats these steps again. The stringst

Answer 1

I'm a C guy most of the day, so I would simply use atoi() do to the conversion:

#include  // header for atoi()

//stream1 >> i3;  // replace this for the line below
i3 = atoi(stream1.str().c_str());

cout << "i3-- " << i3 << endl;

What I'm doing is retrieving a std::string from the stringstream, and from that, getting a const char* to be used as argument for atoi(), which converts a C string to an integer.
