Explanation:
Creating a dynamic array of integers with the given size is what the provided code snippet does. Let's break down the explanation:
int* createArray(int size) {
- This line defines a function called createArray that takes an integer size as a parameter and returns a pointer to an integer.
int* arr = new int[size];
- Inside the function, a dynamic array of integers is created using the 'new' keyword with the size specified by the input parameter.
- The pointer to the array is stored in the variable 'arr'.
return arr;
- Finally, the function returns the pointer to the dynamically allocated integer array.
In conclusion, the code snippet creates a dynamic array of integers with the size specified as an input parameter and returns a pointer to the allocated array.
