shell变量的子串的删除/替换

${#string} 返回$string的长度

${string:position} 在$string中，从$position位置之后开始提取子串

${string:position:length} 在$string中，从$position位置之后开始提取$length长度的子串

VAOs act similarly to VBOs and textures with regard to how they are bound. Having a single VAO bound for the entire length of your program will yield no performance benefits because you might as well just be rendering without VAOs at all. In fact it may be slower depending on how the implementation intercepts vertex attribute settings as they're being drawn.

The point of a VAO is to run all the methods necessary to draw an object once during initialization and cut out all the extra method call overhead during the main loop. The point is to have multiple VAOs and switch between them when drawing.

In terms of best practice, here's how you should organize your code:

initialization:
    for each batch
 generate, store, and bind a VAO

	#include <stdio.h>
	#include <stdint.h>
	#include <fcntl.h>

	#include <unistd.h>

	int main(int argc, const char *argv[])
	{

	#include <time.h>
	#include <iostream>
	#include <limits>

	int TimeZoneOffsetSecond()
	{
	// cache, need compute only once
	static int offset = std::numeric_limits<int>::min();
	if (offset != std::numeric_limits<int>::min())
	{

	# Hello, and welcome to makefile basics.

	# You will learn why `make` is so great, and why, despite its "weird" syntax,
	# it is actually a highly expressive, efficient, and powerful way to build
	# programs.

	# Once you're done here, go to
