Array name take the address is very fun, here to record, if you have different views, welcome message discussion:in most cases, the array name is converted by default to a pointer to the first element of the array . This is a point that we all know. For example, below:int array[3] = {n/a};cout The values for the top two outputs are the same, and at this point the array is converted by default to a pointer to the first element of the array. The value of the first element of the array is obtained

, most of the time they are the same, but there are some differences.For example,%eax registers, which are often used to store the return value of a function. For%eax,%ECX,%edx, and%EBX, they can all be accessed in separate bytes. It is also necessary to mention that these eight registers can be accessed by double-byte.In addition to the above differences, the usage practices of%eax,%ECX,%edx and%EBX,%esi, and%edi are somewhat different, as we will discuss in depth later. Here you can just get t

For those methods (static method) The parameters are zero-based, and for instance methods, 0 is reserved for this.All types occupy one slot (entry) in th

operand of OpenGL es Shader language (Official document, chapter fifth)5.1 OperandsThe OpenGL ES shader language contains the following operators.5.2 Array SubscriptThe array element is accessed through the array subscript operator ([]). This is the only operator that operates an array, and for example, an array element is accessed:Diffusecolor + = lightintensity[3] * NDOTL;5.3 Function callsIf a function has a return value, the function call is usual

structure of the modified property value is: $ (obj). CSS ("Property name", "attribute value");By the comparison between the second and the third we can simply summarize: the property value of the operand (ID, name, title ...). We can use jquery's attr method; Manipulate the object's Style property (Background,color,width,height in CSS ...). We can use jquery's CSS method.When we use jquery to facilitate the collection, we can use each method, each o

Consider: Delete p; // ... Delete p; If in ... Part does not relate to P, then the second "delete p;" Will be a serious mistake, because the implementation of C + + implementation, when referring to VC + + as the implementation of the C + + standard of specific tools can not effectively prevent this (unless through the informal means of prevention). Since delete 0 is defined as harmless, a simple solution would be to execute "deletep" wherever it is executed, followed by "P =

A throw-expression with no operand re-throws the exception currently being handled. such an expression shoshould appear only in a catch handler or in a function called from within a catch handler. the re-thrown exception object is the original exception object (not a copy ). for example: try { throw CSomeOtherException();}catch(...) { // Handle all exceptions // Respond (perhaps only partially) to exception // ... throw; // Pass ex

1. DefineA stack frame is a data structure that supports virtual machines for method invocation and method execution, which is the stack element of a virtual machine stack in a virtual run-time data area. The stack frame stores information such as the local variable table, operand stack, dynamic connection and method return address of the method.Each method starts from the call to the completion of the process, corresponding to a stack frame in the vi
