成功应用void addElement(int val)
{
if(first == null)
{
first = new Element(val, null, null);
last = first;
}
else
{
Element ref = first;
while(ref.next != null)
ref = ref.next;
ref.next = new Element(val, ref, null); //added to the end of the list
last = ref.next; //set the last Element to the one we just created
}
}
当我尝试运行以下/home/uday/ns-allinone-2.35/ns-2.35/DYMO-03-all__ns235.patch
代码时,它会出错,我无法解决该错误。我尽了最大努力,但我失败了......请有人看看代码并帮助我解决错误。测试代码如下:

您的错误:似乎您使用的是 ns 的错误副本,即没有Dymoum的“ns”......或者您的构建失败。安全的方法:使用系统中存在的可执行文件“ns-name”PATH = / usr / local / bin /.
