错误：“类std :: stack <>”没有名为“ pop_back”的成员

Question

void MazeSolver::solveMaze()
{
    stack<Cell> myStack;
    Cell current = myVector.getAt(0, 0);
    myStack.push_back(current);
    int x, y;
    while (myStack.size() != 0)
    {
        current = myStack.pop_back();
        x = current.x_coord;
        y = current.y_coord;
    }
}

I am getting the following compile time error:

/Users/snihalani/dev/c++rec/c++hw at 7:11PM

➜ main.cpp: In member function 'void hw1::MazeSolver::solveMaze()':

main.cpp:55:17: error: 'class std::stack<hw1::Cell>' has no member named 'push_back' main.cpp:59:31: error: 'class std::stack<hw1::Cell>' has no member named 'pop_back'

[1] + 18262 exit 1 g+ --std=c++11 main.cpp

Thanks in advance for the help.

Answer 1

Change push_back to push and pop_back to pop . For more information, use a good reference .

Answer 2

std::stack<> has a member function named pop , and another named push . The stack can only do operations on the back, it is just push and pop .
