lesson2/25_B_return_pointer.c: misleading C example for pointer semantics

[p4sttt]

on slide 61 of lesson 2 (sub-theme Pointers), an example C code snippet is presented to illustrate pointer behavior, specifically returning the address of a local variable

int* get_pointer(void) {
    int i = 42;
    return &i;
}

the slide then juxtaposes this with a Go equivalent, implying similar behavior or direct analogy:

func getPointer() *int {
    var i int = 42
    return &i
}

the C code example for get_pointer() that returns the address of a stack-allocated variable int i immediately leads to Undefined Behavior upon dereferencing the returned pointer in main printf("%d\n", *p);

actually this example is there on purpose to show how Go is DIFFERENT from C. Probably we need to make sure what's on slides.
