ProgramGuruTo append a vector to another vector in C++, you can use the `insert` method, `push_back` method, or range constructor.
In this example,
vector1 and vector2 with different values.insert method on vector1, passing the iterator pointing to the end of vector1 and the iterators of vector2.insert method inserts all elements from vector2 into vector1 at the position indicated by the iterator.vector1 to standard output.#include <iostream>
#include <vector>
int main() {
std::vector<int> vector1 = {1, 2, 3, 4};
std::vector<int> vector2 = {5, 6, 7};
vector1.insert(vector1.end(), vector2.begin(), vector2.end());
for (int num : vector1) {
std::cout << num << " ";
}
return 0;

In this example,
vector1 and vector2 with different values.push_back method on each element of vector2 to append them to vector1.push_back method adds each element from vector2 to the end of vector1.vector1 to standard output.#include <iostream>
#include <vector>
int main() {
std::vector<int> vector1 = {1, 2, 3, 4};
std::vector<int> vector2 = {5, 6, 7};
for (int num : vector2) {
vector1.push_back(num);
}
for (int num : vector1) {
std::cout << num << " ";
}
return 0;

In this example,
vector1 and vector2 with different values.vector2 to vector1 constructor.vector2 to vector1.vector1 to standard output.#include <iostream>
#include <vector>
int main() {
std::vector<int> vector1 = {1, 2, 3, 4};
std::vector<int> vector2 = {5, 6, 7};
vector1.insert(vector1.end(), vector2.begin(), vector2.end());
for (int num : vector1) {
std::cout << num << " ";
}
return 0;
