How do I declare a one-dimensional array in C++?

To declare a one-dimensional array in C++, you can use the syntax: dataType arrayName[arraySize]; For example, int myArray[10]; declares an array of 10 integers.

Can you give me an example of initializing it?

Sure! You can initialize it at the time of declaration like this: int myArray[3] = {1, 2, 3}; This creates an array with three elements.

What if I want to declare an array without specifying the size?

You can initialize an array without specifying the size by providing the values directly: int myArray[] = {1, 2, 3, 4}; The compiler will determine the size based on the number of elements.

Are there any limitations on the size of the array?

Yes, the size of an array in C++ is limited by the available memory and the maximum size defined by the compiler, which is typically a few million elements.
