c++ copy pointer vector to static

To copy a pointer vector to a static vector in C++, you can follow these steps:

1. Create a pointer vector: First, create a vector that holds pointers to the desired objects. For example, if you want to copy a vector of integers, you can declare a vector of integer pointers:

std::vector<int*> pointerVector;

1. Populate the pointer vector: Next, populate the pointer vector with the addresses of the objects you want to copy. For each object, use the & operator to get its address and push it to the pointer vector. For example:

int num1 = 10;
int num2 = 20;
pointerVector.push_back(&num1);
pointerVector.push_back(&num2);

1. Create a static vector: Declare a static vector of the same type as the objects you want to copy. For example, if you want to copy integers, declare a static vector of integers:

std::vector<int> staticVector;

1. Copy the objects: Iterate over the pointer vector and dereference each pointer to access the objects. Use the dereferencing operator * to obtain the object value and push it to the static vector. For example:

for (const auto* ptr : pointerVector) {
    staticVector.push_back(*ptr);
}

1. Access the copied objects: You can now access the copied objects in the static vector using its regular vector operations. For example, to print the copied integers:

for (const auto& num : staticVector) {
    std::cout << num << " ";
}

This should result in the output: 10 20.

By following these steps, you can copy a pointer vector to a static vector in C++.
