I have no idea what does this code means even though the book explained it. I think maybe it didn't explain well enough. Can anyone tell me what does this code means?
I also have no idea about the char 256 thing =,=Code://This programme shows an example of using an if statement to check for no input #include <iostream> #include <string> int main() { using namespace std; char response[256]; cout<< "What is your name? "; cin.getline(response,256); if (strlen(response) == 0) cout<< "You must tell me your name..."; else cout<< "It's nice to meet you, "<< response; return 0; }
