所以,如果你有另外一个对象叫做myAppObject拥有方法,可以访问数组对象,以及插入对象到一个数组,你可以把前面的例子写成如下的样子: [[myAppObject getArray]insertObject:[myAppObject getObjectToInsert]atIndex:0]; 虽然前面的例子都是传递消息给某个类的实例,但是你也可以传递消息给类本身。当给类发消息,你指定的...
using System;publicclassHappyProgram{publicstaticvoidMain(){ Console.WriteLine("Enter a number: ");intYourNumber=Convert.ToInt16(Console.ReadLine());if(YourNumber >10) Console.WriteLine("Your number is greater than ten");if(YourNumber <=10) Console.WriteLine("Your number is ten or smaller")...
objc_setAssociatedObject(array, &overviewKey, nil, OBJC_ASSOCIATION_ASSIGN); 其中,被关联的对象为nil,此时关联策略也就无关紧要了。 使用函数objc_removeAssociatedObjects可以断开所有关联。通常情况下不建议使用这个函数,因为他会断开所有关联。只有在需要把对象恢复到“原始状态”的时候才会使用这个函数。 7.3.4...

To conform to the dynamic library naming conventions assumed by the link loader and the compilers, assign names to the dynamic libraries that you create with the prefix lib and the suffix .so. For example, libmyfavs.so could be referenced by the compiler option -lmyfavs. ...
The -xO2 level does not assign global, external, or indirect references or definitions to registers. It treats these references and definitions as if they were declared volatile. In general, the -xO2 level results in minimum code size. -xO3 Performs like -xO2, but also optimizes references...
Python C/C++ 拓展使用接口库(build in) ctypes 使用手册 ctypes 是一个Python 标准库中的一个库.为了实现调用 DLL,或者共享库等C数据类型而设计.它可以把这些C库包装后在纯Python环境下调用. 注意:代码中 c_int 类型其实只是 c_long 的别

Assign a value to a bit. If c != 0 then set bit; otherwise clear bit. void bit_array_assign_bit(BIT_ARRAY* bitarr, bit_index_t b, char c) Fast MACROs You can also use the following which are implemented as MACROs without bounds checking: bit_array_get(BIT_ARRAY *arr, bit_ind...
If you want to take an item out of an array at a given index and continue using it, usecJSON_DetachItemFromArray, it will return the detached item, so be sure to assign it to a pointer, otherwise you will have a memory leak.
