Question

自从我上次使用向量和其他结构（大多数在大学）编程以来，已经有好几年了，现在我遇到了一个问题，我无法确定这个知识差距。< / p>

所以，这里是代码的一部分，我认为它有问题：

if (pos == -1) {
    cout<< "New Neighbor\n";
    neighborRecord newRec; //declaring newRec as type struct neighborRecord

    newRec.id = nodeID; //receiving values
    newRec.x = x_ngb;
    newRec.y = y_ngb;
    newRec.z = z_ngb;
    newRec.x_dst = x_dst; //L
    newRec.y_dst = y_dst;
    newRec.z_dst = z_dst;
    newRec.ts = simTime().dbl();
    newRec.timesRx = 1;
    newRec.ic = IC;
    cout<< "NEW REC IC" << newRec.ic<<"\n"; //until here i checked and it's all ok with variables

    neighborTable.push_back(newRec);

但是当我创建一个循环来读取矢量时，我得到了错误的值。这是循环：

for (int i = 0; i < neighborTable.size(); i++){

   trace()<< "ID: "<< neighborTable[i].id <<"\n";
   trace()<< "X : "<< neighborTable[i].x<<"\n";
   trace()<< "Y : "<< neighborTable[i].y<<"\n";
   trace()<< "Z : "<< neighborTable[i].z<<"\n";
   trace()<< "XDST: "<< neighborTable[i].x_dst<<"\n";
   trace()<< "YDST: "<< neighborTable[i].y_dst<<"\n";
   trace()<< "ZDST: "<< neighborTable[i].z_dst<<"\n";
   trace()<< "TS: "<< neighborTable[i].ts <<"\n";
   trace()<< "TIMESRX: "<< neighborTable[i].timesRx<<"\n";
   trace()<< "IC:  "<< neighborTable[i].ic<<"\n";


}

结果之一：

ID：30

X：26.4458

Y：38.1514

Z：0

XDST：5.43472e-323

YDST：51.8989

ZDST：50.9054

TS：1.13635e-322

TIMESRX：20615843

IC：0

我不知道访问该向量时是否有什么，我不知道如何使其工作。有趣的是，我用较少的变量进行了测试，并且工作正常。当我向结构中添加更多变量时，我才刚刚看到这个错误。

从C ++中的结构向量中获取错误的值
