array initialization declaration c++

To initialize and declare an array in Objective-C, you can use the following syntax:

// Declare an array
NSArray *arrayName;

// Initialize an array with objects
arrayName = [[NSArray alloc] initWithObjects:object1, object2, object3, nil];

// Accessing array elements
id element = [arrayName objectAtIndex:index];

In C++, you can initialize and declare an array using the following syntax:

// Declare an array
dataType arrayName[arraySize];

// Initialize an array with values
dataType arrayName[arraySize] = {value1, value2, value3};

// Accessing array elements
dataType element = arrayName[index];

Please note that in Objective-C, NSArray is used for dynamic arrays, while in C++, you can use either static arrays or dynamic arrays using std::vector or std::array.
