The correct way to initialize an array in C++ is:

int arr[3] = {1, 2, 3};

and

int arr[] = {1, 2, 3};

The first one explicitly defines the size of the array and initializes it. The second one lets the compiler determine the size of the array based on the number of elements in the initialization Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
