将向量附加到向量中可以简单地通过向量insert()
方法来完成。
Begin Declare a function show(). Pass a constructor of a vector as a parameter within show() function. for (auto const& i: input) Print the value of variable i. Declare vect1 of vector type. Initialize values in the vect1. Declare vect2 of vector type. Initialize values in the vect2. Call vect2.insert(vect2.begin(), vect1.begin(), vect1.end()) to append the vect1 into vect2. Print “结果向量为:” Call show() function to display the value of vect2. End.
#include <iostream> #include <vector> #include <algorithm> using namespace std; void show(vector<int> const &input) { for (auto const& i: input) { std::cout << i << " "; } } int main() { vector<int> v1 = { 1, 2, 3 }; vector<int> v2 = { 4, 5 }; v2.insert(v2.begin(), v1.begin(), v1.end()); cout<<"结果向量为:"<<endl; show(v2); return 0; }
输出结果
结果向量为: 1 2 3 4 5
