TArray Resize is a method used in the C++ programming language to resize a dynamic array. It resizes the array to a specified size by either increasing or decreasing its size. This method can be used in various packages and libraries depending on the implementation.

Example 1: Using the TArray Resize method to increase the size of an array

#include 
#include 

int main() {
   std::vector v;
   v.push_back(10);
   v.push_back(20);
   v.push_back(30);
   
   std::cout << "Original Vector: ";
   for(auto i : v) {
      std::cout << i << " ";
   }

   v.resize(5);
   
   std::cout << "\nResized Vector: ";
   for(auto i : v) {
      std::cout << i << " ";
   }
   
   return 0;
}

In this example, we are using the std::vector package to create a dynamic array. The method resize() is used to increase the size of the array to 5. The output displays both the original vector [10 20 30] and the resized vector [10 20 30 0 0].

Example 2: Using the TArray Resize method to decrease the size of an array

#include 
#include 

int main() {
   std::array arr{1, 2, 3, 4, 5, 6};
   
   std::cout << "Original Array: ";
   for(auto i : arr) {
      std::cout << i << " ";
   }

   arr.resize(3);
   
   std::cout << "\nResized Array: ";
   for(auto i : arr) {
      std::cout << i << " ";
   }
   
   return 0;
}

In this example, we are using the std::array package to create a static array. The method resize() is used to decrease the size of the array to 3. The output displays both the original array [1 2 3 4 5 6] and the resized array [1 2 3]. The package library used in both these examples is the Standard Template Library (STL).
