Japonca Dersi / Dai 1-ka

 

Almış olduğum alan dışı seçmeli dersi olan Japonca (JPN 201) dersinde öğrendiklerimi paylaşayım dedim, belki birilerinin işine yarar. Ancak biz Japoncayı İngilizce tarzı yazarak öğrendik, Japonca harflerle değil. O yüzden ben de o şekilde yazacağım.
(Soldaki resim de Japonca’da Z harfi, kendimden bir iz=) )
Haydi ilk dersten başlayalım!
Dai 1-ka (1.Ders)
Japonca ekleri bakımından Türkçe?ye benziyor. Mesela bunu göstermek için bir cümle yazalım…

x=3;
if(! (x>10) )
printf(?%d?,x); //it will print ?3?.
if(!0)
printf(?hey?); //it will print ?hey?.
if(!x)
printf(?%d?,x); //it will print nothing.

C / C++ Courses ? 10 (Pre-increment and Post-increment)

Pre-increment and Post-increment

Pre-increment changes the value of the variable, and then makes the calculation or processes which should be done. (It?s written like this: ?++x ?)

Post-increment makes the processes and then changes the value of the variable. (It?s written like this: ?++x ?)

Decrement versions of these are the same. (?–x? or? x–?)

int x=3;

printf(?%d?, ++x); //it will change the value of x to 4 and then print 4…
