39,695,542 | I have three tables, `tbl_doctors_details`, `tbl_time` and `tbl_token`.
I have to select the details from `tbl_time` or `tbl_token`. That is if for particular doctor in hospital have `t_type` is `time` then select from `tbl_time` else select from `tbl_token`.
For example, for `doctor_id` is 100 and `hospital_id` 1, t... | 2016/09/26 | [

] | Second function will be called in both the cases, as the your redefining the function definition.
Also there is no function overloading in javascript, in the second case change function signature( i.e arguments it takes) will redefine the same A function (defined 1st). | In both cases the second function will be called because it overwrites the global variable `A` when declared.
It's similar to writing:
```
var a = 1;
var a = 2;
a === 2; // true

16,703,886 | Where are static local variables stored in memory? Local variables can be accessed only inside the function in which they are declared.
Global static variables go into the .data segment.
If both the name of the static global and static local variable are same, how does the compiler distinguish them? | 2013/05/23 | [

] | Static variables go into the same segment as global variables. The only thing that's different between the two is that the compiler "hides" all static variables from the linker: only the names of extern (global) variables get exposed. That is how compilers allow static variables with the same name to exist in different... | As mentioned by dasblinken, GCC 4.8 puts local statics on the same place as globals.
More precisely:
* `static int i = 0` goes on `.bss`
* `static int i = 1` goes on `.data`
Let's analyze one Linux x86-64 ELF example to see it ourselves:
```
#include <stdio.h>
int f() {
static int i = 1;
i++;
return i;... |
