一段代碼開始新的學習

1.int quotient, numertor, denominator;
定義整形的變量，object-c中常見數據類型如下：
1.1 整型 int integerType = 1;
1.2 浮點型 float floatType = 3.14;
1.3 雙浮點型 double doubleType = 3.1415;
1.4 短整型 short int shortType = 50;
1.5 長整型 long long int longlongType = 123456789L;
2.quotient = numertor/denominator;
變量相除（numertor/denominator）然后將得到的值賦給商（quotient）
3.NSLog(@"The fraction is %i/%i /nthe quotient is %i", numertor, denominator, quotient);
NSLog中%i的使用方法與C語言中相同，即只要在NSLog的例程中發現%i字符，會自動用例程中的對應變量替換顯示。/n為換行符。
程序運行結果如下：
