C++ 在C+中初始化我自己的类的向量+；在Xcode IDE中

我目前遇到的问题如下：

我试图在main.cpp文件中构造一个只包含SingleBox对象的向量（SingleBox是我定义的一个类），但是，当我试图填充或调整该向量的大小时，该向量从不包含任何SingleBox对象，并且在my main.cpp文件中从未执行填充或调整向量大小的尝试下面的代码

提前感谢您为解决此问题提供帮助的任何人

文件main.cpp

#include <iostream>
#include "SingleBox.h"
#include "NineBox.h"

int main( int argc, const char * argv[] )
{
    std::vector< SingleBox > vec;
    std::cout << "Below is the attempt to populate: \n";
    vec.push_back( SingleBox( 0, 0 ) );
    std::cout << "Nothing from this point onward executes...\n";
    std::cout << "The size: " << vec.size() << std::endl;

    return 0;
}

#include "SingleBox.h"

// SingleBox constructor initializes each data member
SingleBox::SingleBox( int nineBoxNum, int boxVal )
{
    setNineBoxNum( nineBoxNum );
    setBoxValue( boxVal );
    setIndicator( false );
    possibilities = {1, 2, 3, 4, 5, 6, 7, 8, 9};
} // end SingleBox constructor

// set new NineBox number
void SingleBox::setNineBoxNum( int nineBoxNum )
{
    nineBoxNumber = nineBoxNum;
} // end function setNineBoxNum

// set new BoxValue number

    boxValue = boxVal;

}

// return the BoxValue

// set value to zero if in possibilities vector

{
    int zeroCnt = 0;
    int value = 0;

    for ( int i = 0; i < possibilities.size(); i++ ) {
        if ( possibilities[ i ] == number ) {
            possibilities[ i ] = 0;
            break;

        }
        else {

        }
    }

    if ( zeroCnt == possibilities.size() - 1 ) {
        boxValue = value;
        setIndicator( true );
    }
} // end function updateProbs

// print all data members of the class to the console
void SingleBox::debugPrinter(  )
{
    std::cout << std::endl;
    std::cout << "SingleBox class contains the following \n";
    std::cout << " - Completion status = " << completionStatus << std::endl;
    std::cout << " - NineBoxNumber     = " << nineBoxNumber << std::endl;
    std::cout << " - BoxValue          = " << boxValue << std::endl;

标准：：向量vec；
std:：coutXcode IDE没有运行我的部分代码，因为设置了断点。通过g++编译运行代码验证了我的代码是可操作的，从Xcode中删除断点允许我的代码在IDE中操作。
你说下面的代码永远不会执行是什么意思？发生了什么？编译中有错误吗er？XCode是否会立即让您进入调试模式，尝试找出哪里出了问题（AKA
gdb
）？请阅读Xcode并不表示任何错误或警告。在尝试初始化向量后，它只是不向控制台输出任何消息。我复制了您的程序，将其粘贴到单个文件中，然后编译并执行它：它似乎对我来说运行良好。您是否尝试在IDE之外对其进行编译？不，我没有尝试使用g++编译器。但是，我会继续，并尝试这样做，因为这是有效的一点。
