The result appears that the company is growing bomb.
tịrmās̄ 2 Year 2019 Income 13,612 million baht.
tịrmās̄ 2 Year 2020 Income 27,528 million baht.
Think of growth up to 102 %
The company has income coming from
Game business 44 %
Ecommerce Business 41 %
Business to sell other products 15 %
Now if we separate the details of each business, starting from
Game business which the company is called together Digital Entertainment
This group of businesses are serving games in the Southeast Asia.
On PC like PUBG LITE, League of Legends and FIFA Online 4
On smartphones like ROV, Call of Duty, Speed Drifters and Free Fire
Game revenue grows 67 % as a result of quarterly players.
Aka the company called Quarterly Active Users. It explodes through 500 million accounts.
Increased to over 100 million accounts compared to the same period of last year.
Apart from the game the company brought to the service of the collaboration.
With partners like Tencent will grow well
Free Fire's developed game is well done by making a record.
Players simultaneously reached 100 million accounts in one day. The last quarter.
It's not sold out just yet..
If we think Sea Limited's game business will grow the most, we might be wrong.
Because another business is growing well. That's an eCommerce business.
Under the brand we are familiar with, Shopee
Did you know that Shopee has orders this quarter?
Up to 615.9 million orders have grown by over 150 %
With regard to total trading volume (GMV)
Total of over 2.5 hundred thousand baht
Such a matter resulting in income only in Shopee's section.
Up to 1.1 ten billion baht in the last quarter.
However, behind the growth of the company explosion.
Important part of COVID-19 plague crisis
That makes us spin on more online trading platforms
Including more free time to play games on PC and on smartphone.
Another part comes from sales and marketing expenses.
Including research and development costs that have risen as well.
That's why even Sea Limited is making 102 % of explosive income.
But the company is still a 41 % loss or worth
A loss of over 1.2 billion baht.
But it seems that investors don't give that much importance to the loss.
And focus on the number of gaming business accounts and orders from ecommerce businesses that are more exploding.
Because after announcement of results in this quarter, Sea Limited's value spikes 9 % immediately.
Make the present Sea Limited owner of Shopee and Garena
I have just founded a business for 11 years. It has a company worth up to 2 trillion Baht.
More than PTT. The most valuable company in Thailand is 2 times better..

call by reference 在 Re: [理工] 想請問97清大資最後一題- 看板Grad-ProbAsk 的八卦
※ 引述《jas1123kimo (傑森)》之銘言：
: https://ppt.cc/og7m
: call by value by value-result by reference的差別在哪裡~
: 要怎麼呢?~麻煩大加了!感謝
幾個參考資料
https://c2.com/cgi/wiki?CallByValueResult
https://c2.com/cgi/wiki?CallByReference
https://0rz.tw/aSrf4
(1) Call by value: "you get a copy of the data or object"
以題目的舉例而言，swap將參數first、second以pass by value的方式傳進來，
也就是說，在swap裡面不管將first、second這兩個變數如何更改，
原本的caller中的變數並不會被改變；
舉例:
int x = 1; //global variable
void foo(int a) //a被copied成1
{
// a is 1; x is 1
a = 3;
// a is 3; x is 1
x = 4;
// a is 3; x is 4
}
void main()
{
// x is 1
foo(x);
// x is 4
}
(2)Call by reference:"you get an alias of the data or object"
A ParameterPassing mode where a reference (or if you want to be politically
incorrect, a pointer) to the actual parameter is passed into the formal
parameter; when the callee needs the formal parameter it dereferences the
pointer to get it.
以題目舉例而言，swap將參數first、second以pass by reference的方式傳進來，
那麼這兩個參數在swap中如果被更改，那原本caller中的變數也會被改變；
以上面的例子來說，那一行就會印100。
舉例:
int x = 1; //global variable
void foo(int a) //有aliasing，a和x都指向同一個位置
{
// a is 1; x is 1
a = 3
// a is 3; x is 3
x = 4
// a is 4; x is 4
a = 5
// a is 5; x is 5
}
void main()
{
// x is 1
foo(x);
// x is 5
}
(3)Call by value-result
In CallByValueResult, the actual parameter supplied by the caller is copied
into the callee's formal parameter; the function is run; and the (possibly
modified) formal parameter is then copied back to the caller.
The (semantic) differences between CallByReference and CallByValueResult are:
"No alias is created between the formal and actual parameters. If lexical
scoping is used, the difference can be apparent."
舉例:
int x = 1; //global variable
void foo(int a) //因為沒有aliasing，foo將1 copied給a，
a最後被assigned成3，foo再將3 copied回main。
{
// a is 1; x is 1
a = 3;
// a is 3; x is 1
x = 4; //因為沒有aliasing，雖然這行將x改為4，
但當foo結束之後，會把3 copied回main，因此x最後為3
// a is 3; x is 4
}
void main()
{
// x is 1
foo(x);
// x is 3
}
附註:
lexical scoping:
也叫做static scoping，簡單來說就是變數的scope只在它定義的那個區塊，
離開了那個區塊，那個變數就不再存在。
來看這個例子:
x=1 # this is a global variable
function g () { echo $x ; x=2 ; }
function f () { local x=3 ; g ; }
f # does this print 1, or 3?
echo $x # does this print 1, or 2?
如果是lexical scoping的話，
最後兩行分別會印1、2，
因為g的定義在f的外面，所以g他不知道f將 x assign成3，
所以先echo $x，會印1，然後再將 x assign成2
最後一行的echo $x會印2；
順便一提，相反的就是叫做dynamic scoping，
其變數的scope只要function還在running就會存在，
因此，上面的例子就會先印3(看得見f將x assign成3)
再印1(global variable的scope是整個程式)
總結，Call by reference和Call by value-result的差別在於，
Call by reference有引進aliasing，Call by value-result沒有。

後來想起來以前老師上課說的，
「Aliasing」的意義就像是綽號，
也就是caller裡給的變數，它的綽號就是callee傳進來的參數，
對程式來說，這兩個變數會被視為同一個~
所以callee的參數被改變，caller中的變數也會跟著被改變。
印象中macro是在compile time的時候把程式碼展開預先處理吧，
藉由compiler的preprocessor~
call by value-"result" 好像名字就有隱含著它的意義了XDD
傳參數方式是call by value，但是當副程式執行完會把result複製回去
