program skips over getline [duplicate]

Answer 1

Adding a

cin.ignore(2000, '\n');

before the input call fixes the problem!

Answer 2

After you read choice in the displayMenu subroutine, you leave the remainder of the user's input line. Specifically, you leave the end-of-line indicator: '\n'. Later, when you read newperson->name, you are actually retrieving the remainder of the menu line, and not the name line.

You can use istream::ignore to consume the rest of menu choice line, before trying to read the name.

Replace the last two lines of displayMenu with these:

cin >> choice;
std::cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
return choice;
