Detecting ENTER key in C++

Question

I have a program like this,

char name[100];
char age[12];
cout << \"Enter Name: \";
cin >> name;

cout << \"Enter Age: \";
cin >> age         


        

Answer 1

One way to do it is to use getline to read the input, then test the length of the input string. If they only press enter, the length of the line will be 0 since getline ignores newlines by default.

std::string myString = "";

do {
     std::cout << "Press ENTER to exit" << std::endl;
     std::getline(std::cin, myString);
} while (myString.length() != 0);

std::cout << "Loop exited." << std::endl;
