Explanation:
Dynamic Memory Allocation:
int *arr = (int *)malloc(3 * sizeof(int));
Allocates memory for an array of three integers using malloc.
The sizeof(int) ensures that the correct size of an integer is allocated.
The cast (int *) is used to cast the void pointer returned by malloc to an int pointer.
Assigning Values to Array Elements
arr[0] = 1;
arr[1] = 2;
arr[2] = 3;
Assigns the values 1, 2, and 3 to the elements of the dynamically allocated array.
Printing the Value of the First Element:
printf("%d\n", *arr);
Prints the value of the first element in the array using printf and dereferencing (*arr).
Freeing Dynamically Allocated Memory:
free(arr);
Releases the memory previously allocated by malloc using the free function. This step is important to prevent memory leaks.
Return 0:
return 0;
Indicates successful execution of the program.
The output of the program will be 1
