For-Loop Skipping getline C++

Question

I'm having a problem where my for-loop skips over the getline function. If I replace it with std::cin then it works, so I think it's something related to what I inputted in getline.

Here's my code.

void setLocations(int amount) {
    locations = new std::string[amount];
    locations[0] = startingLocation;

    // starts at 1 because we want to skip first index. The amount is set at 2 by default, so the loop should iterate at least once.
    for (int x = 1; x < amount; x++)
        std::getline(std::cin, locations[x]);    
}

May be you use 'std::cin>>someVar' before 'setLocations' function call, which doesn't consume newline. To resolve, use this code segment before 'for' loop

std::cin.ignore(1, '\n');

I got an error where it says I cannot initialize a parameter of int_type when using the cin.ignore(1, "\n"); – Jacob Macallan Sep 30 '15 at 20:49
@Xari, sorry my mistake use '\n' not "\n". – ashiquzzaman33 Sep 30 '15 at 20:57
