assignment makes integer from pointer without a cast

This warning message is related to C language and it usually occurs when a pointer is used in a context where an integer is expected or vice versa.

For example, consider the following code snippet:

int *ptr;
int num = ptr; // Attempting to assign a pointer to an integer

In this case, the `ptr` is a pointer to an integer, but it is being assigned to an `int` variable `num` without being dereferenced. This results in the warning "assignment makes integer from pointer without a cast".

To fix this issue, you can either dereference the pointer to get its value or cast the pointer to the desired integer type. For instance:

int *ptr;
int num = *ptr; // Dereferencing the pointer to get its value

// OR

int *ptr;
int num = (int)ptr; // Casting the pointer to an integer type

It's important to note that casting a pointer to an integer type should be done with caution as it can result in unexpected behavior if the pointer doesn't point to a valid memory location.
