vector类

vector类是一个能够存放各种数据类型的动态数组，熟练掌握vector能够帮助我们帮一些问题简单化。 vector的头文件#include 一.vector类的构造 1.无参构造 2.初始化n个值的构造 3.拷贝构造 4.用区间构造 5.迭代器构造 int main() { vectorv1; vectorv2(10,2);//10个2的数组 vectorv1(10,'c'); vectorv3(v2); int arr[] = { 1, 2, 3, 4, 5 }; vectorv4(arr,arr+5); vectorv5(v4.begin()+1,v4.end()-1);

are discouraged. What does this mean and how can it be fixed? This is a warning message in Java which suggests that using raw types, such as "Vector," without generic types is not recommended. It is recommended to use generic types to ensure type safety and avoid potential errors. To fix this warning, you can specify the generic type of the vector, for example, "Vector<String>," to indicate that the elements stored in the vector are of type "String."
