stack overflow

Question

int* func() {
    int* mem = malloc(1024);
    return mem;
}

int* mem = func();

Can anyone pls explain the code?

Comments

malloc(..) is used for allocating memory. So the code allocates a memory of 1024 bytes and provides a pointer (to the first byte) to the variable (a pointer) named mem.
