一段代码开始新的学习

1.int quotient, numertor, denominator;
定义整形的变量，object-c中常见数据类型如下：
1.1 整型 int integerType = 1;
1.2 浮点型 float floatType = 3.14;
1.3 双浮点型 double doubleType = 3.1415;
1.4 短整型 short int shortType = 50;
1.5 长整型 long long int longlongType = 123456789L;
2.quotient = numertor/denominator;
变量相除（numertor/denominator）然后将得到的值赋给商（quotient）
3.NSLog(@"The fraction is %i/%i /nthe quotient is %i", numertor, denominator, quotient);
NSLog中%i的使用方法与C语言中相同，即只要在NSLog的例程中发现%i字符，会自动用例程中的对应变量替换显示。/n为换行符。
程序运行结果如下：
2014-10-27 21:30:48.556 Demo1[1521:67965] The fraction is 10/2 the quotient is 5PRogram ended with exit code: 0
