Dynamic Memory Allocation for Binary Tree in C

This statement dynamically allocates memory for a new BinaryTree structure using the 'malloc()' function. The size of the allocated memory is determined by the 'sizeof(BinaryTree)' function, which evaluates to the number of bytes required to store a BinaryTree structure.

The 'malloc()' function returns a pointer to the allocated memory block, which is then assigned to the variable Bt. This allows the program to access and modify the newly created BinaryTree structure.
