https://stackoverflow.com/questions/633549/how-to-copy-the-contents-of-stdvector-to-c-style-static-array-safely The problem is that you're adding things to the vector so it ends up with more elements than were in themyarrarray that you initialized it with. If you want to copy the vect...
我正在写一段代码,其中我需要复制一个指向向量或它的某个部分的指针-定义如下: std::unique_ptr<std::vector<unsigned int>> filtered_profile_ptr = std::make_unique<std::vector<unsigned int>>((int)baselength); 指向另一个指向向量的指针-定义为: std::unique_ptr<std::vector<unsigned int>...

方法1:vector<int>v1(v2); 或vector<int> v1= v2; 方法2:使用swap进行赋值: vector<int> v1(); v1.swap(v2);//将v2赋值给v1,此时v2变成了v1 方法3:使用函数assign进行赋值: vector<int> v1(); v1.assign(v2.begin(), v2.end());//将v2赋值给v1...
// printing new vector cout << "The new vector elements entered using copy() : "; for(int i=0; i<v2.size(); i++) cout << v2[i] << " "; cout << endl; // using copy_n() to copy 1st 4 elements copy_n(v1.begin(), 4, v3.begin()); ...
C++ STL | Copying a vector: Learn - different ways to copy a vector in C++ STL, Shallow copy vs Deep copy, Different copy methods, etc.
For example, the following code uses copy to both copy the contents of one vector to another and to display the resulting vector: vector《int》 from_vector; for( int i = 0; i 《 10; i++ ) { from_vector.push_back( i );
