In function ‘int returnShortestWeightedBranch(std::vector<route,std::allocator<route> >*)’:
error: name lookup of ‘jj’ changed for ISO ‘for’ scoping
note: (if you use ‘-fpermissive’ G++ will accept your code)

代码是：

for (int i = 0; i< routeVector.size(); i++)
        {
            if (routeVector[i].exitPoint == exitPointDetailsVector[preserveL].exitPoint)
            {
                cout << "\n-----------parent: " << routeVector[i].exitPoint;
                branch obj;
                obj.connectedExitPoint = exitPointDetailsVector[preserveI].exitPoint;
                routeVector[i].selectedBranchesVector.push_back (obj);

                for (int jj = 0; jj < routeVector[i].selectedBranchesVector.size(); jj++);
                {
                    cout << "\n-----------branch: " << routeVector[i].selectedBranchesVector[jj].connectedExitPoint;
                }
            }
        }

这里有什么问题？

编辑1：

我改变了以下几点：

for (int jj = 0; jj < routeVector[i].selectedBranchesVector.size(); jj++);

至：

int jj;
for (jj = 0; jj < routeVector[i].selectedBranchesVector.size(); jj++);

现在正在工作！我不明白原因.
