How do I handle white-space and return-key if the program expects the user to enter text (a name for instance).
char ch[100];
cout << "enter something: ";
cin >> ch;
cout << ch << endl;
How can the program be notified if the user
Like this:
#include <iostream>
#include <string>
int main()
{
for (std::string line; std::getline(std::cin, line); )
{
if (line.empty())
{
// handle blank input
}
std::cout << "You said: " << line << "\n";
}
}
This doesn't trim whitespaces yet; that can be done easily by modifying line at the beginning of the loop, e.g. using this code and adding trim(line); at the beginning.
