What is the method to assign values to a dynamic array in C++?

In C++, dynamic arrays can be created using the new operator and assigned values using the assignment operator =. Here is a common method:

1. Create a dynamic array using the new operator and assign it to a pointer variable.

int size = 5; // 数组大小
int* arr = new int[size]; // 创建动态数组并分配内存

1. Traverse the array using a looping structure and assign values to its elements using the assignment operator =.

for (int i = 0; i < size; i++) {
    arr[i] = i + 1; // 给数组元素赋值
}

Caution: after using dynamic arrays, remember to use the delete operator to release memory.

delete[] arr; // 释放动态数组内存
