Cin.getline and char arrays

Question

Testing with combing two char arrays together.

Used this and only prints enter your name. Please help:

#include <iostream>

using namespace std;

int main()
{

char str[20];

cout << "Enter Your Name::";

// see the use of getline() with array

// str also replace the above statement

// by cin >> str and see the difference

// in output

cin.getline(str, 20);

cout << "\nYour Name is:: " << str;

return 0;
}

Answer 1

Unfortunately sololearn's code playground doesnt understand what "std::cin::getline()" is and doesn't ask for input, hence an empty input file goes to the server.

One way to counter is to use an alternative method of taking input ( as Ipang pointed out )

Or

Put a deceptive "cin" or "std::getline" somewhere in your program to force code playground to prompt the input dialog box.

Answer 2

std::cin::getline() is not supported in Code Playground. Use C++ std::string instead of char[] and std::getline().

std::string str {};
std::getline(std::cin, str);
std::cout << str << '\n';
