str.erase(pos,len) str.clear(); 9. 交换字符串 swap(str1,str2); 10. C --> C++ char *cstr = "Hello"; string str1; cstr = cstr; string str2(cstr); 对于ACMer来说,C的字符串处理要比C++的方便、简单,尽量用C的字符串处理函数。 C++中string类常用算法 string类的构造函数: string(const...
Clear: 将bool变量设为false。 Exchange:将指定位置的值设置为传入值,并返回其旧值。 template<typenameT>TExchange(T*addr,constT&newVal){ToldVal=*addr;*addr=newVal;returnoldVal;} Compare And Swap(CAS):将指定位置的值与期望值比较,如果相等则赋值为新值,如果不等则将期望值设置为自身。返回是否设置成...

In C/C++ > Advanced, clear the "Compile As" option. This means the file will be built as Objective-C(++) based on the file extension (by not setting/TC//TPflags that otherwise cause the file to be built as C/C++ irrespective of its extension). ...
clear() Removes all elements from the container. Clone() Creates a new object that is a copy of the current instance. (Inherited from ICloneable) CopyTo(Array, Int32) Copies the elements of the ICollection to an Array, starting at a particular Array index. (Inherited from ICollection)...
当调用erase或clear释放或者说是删除里面的数据时,其内存空间并不会释放,仅仅只是清空了里面的元素。 如果需要空间动态缩小,vector<Point>().swap(pointVec); //或者pointVec.swap(vector<Point> ()),vector的默认构造函数建立临时vector对象 如果vector中存放的是指针,那么当vector销毁时,这些指针指向的对象不会被...
int main (){queue<int> a;//队列的声明a.push(1);//在队头插入一个新元素;a.pop();//弹出队尾元素a.front();//返回队头a.back();//返回队尾//优先队列中a.top();//取最大值a.pop();//去最大值//注意:队列没有clear 函数q = queue<int>();//重新初始化一个队列,起到清除队列的效果...
