local-variables

问题 I know this is a very basic question but I am really stuck on it. In fact I am absolutely newbie in GCC syntax. I want to have local variables (Stack addresses with labels) without using extended inline assembly. Something like the following code in Intel syntax: DATA1 DB 100 MOV AL, DATA1 This is the code I guess may substitute in GCC: int someFunction(int x) { __asm__ volatile( "function1:" ".data;" ".2byte $4 data1 ;" ".text;" "pushq %rbp;" "movq %rsp , %rbp ;" "movl var , %eax;" // this

问题 The following code works in Python 2.7, to dynamically inject local variables into a function scope: myvars = {"var": 123} def func(): exec("") locals().update(myvars) print(var) func() # assert "var" not in globals() It's a bit subtle, but the presence of an exec statement indicates to the compiler that the local namespace may be modified. In the reference implementation, it will transform the lookup of the name "locals" from a LOAD_GLOBAL op into a LOAD_NAME op, enabling addition to the

问题 I am creating some small programs with x86 assembly, and it's my first time using a low level language so I'm not used to it. In high level languages I rarely use global variables, but I've seen a lot of tutorials using global variables in assembly, so I'm not sure when to use global variables instead of local variables. By global variables I mean data created in the .bss and .data segments, and by local variables I mean data allocated on the stack of the current procedure, using the stack

问题 I'm a little Confused about this code result: #include <stdio.h> int g; void afunc(int x) { g = x; /* this sets the global to whatever x is */ } int main(void) { int g = 10; /* Local g is now 10 */ afunc(20); /* but this function will set it to 20 */ printf("%d\n", g); /* so this will print "20" */ return 0; } Why the result is 10 Not 20 ? 回答1: Calling afunc changes the global g , and main retains its local g . Entering a function doesn’t swap its scope with the global scope. Each function*

问题 I am a young programmer that is learning python and struggling to implement an AI (using minimax) to play TicTacToe. I started watching a tutorial online, but the tutorial was on JavaScript and thus couldn't solve my problem. I also had a look at this question ( Python minimax for tictactoe ), but it did not have any answers and the implementation was considerably different from mine. EDIT: the code you will find below is an edit suggested by one of the answers (@water_ghosts). EDIT #2: I

问题 ASP.NET 4.0 Webforms project. I have the following in my code-behind. public partial class _Default : System.Web.UI.Page { private string testVar; protected override void OnInit(EventArgs e) { string testVar = "test"; } protected void Page_Load(object sender, EventArgs e) { var whatsTheValue = testVar; } } I'm setting a break point inside each method. When the local variable, testVar , is set in OnInit , if I quick watch the instance variable, it also has the value "test". When I play through

问题 I have a nested if in Lua. I have a variable inside the second if layer that I want to use in the first layer. The variable is npcSpecimen . if conditions then local npcType = util.pickRandom(self.npcTypes) local npcSpecimen = "" if npcType == "spacebandit" then local npcSpecimen = util.pickRandom(self.npcSpecies) else local npcSpecimen = util.pickRandom(self.npcSpeciesMutant) end local npcId = space.spawnNpc(spawnPosition, npcSpecimen, npcType) end If written this way, npcSpecimen will
