std::cin

Input: Executing std::cin >> v discards any whitespace characters in the standard input stream, then reads from the standard input into variable v. It returns std::cin, which has type istream, in order to allow chained input operations.

int _tmain(int argc, _TCHAR* argv[])
{
        // ask for the person's name
        std::cout << "Please enter your first name: ";

        // read the name
        std::string name;         // define name
        std::cin >> name;         // read into

        // write a greeting
        std::cout << "Hello, " << name << "!" << std::endl;

    std::string stars(100, '*');      // construct the variable
    std::cout << stars;
    return 0;

}
