structure

Consider these two cases : struct customType { dataType1 var1; dataType2 var2; dataType3 var3; } ; customType instance1; // Assume var1, var2 and var3 were initialized to some valid values. customType * instance2 = &instance1; dataType1 firstMemberInsideStruct = (dataType1)(*instance2); class CustomType { public: dataType1 member1; dataType2 member2; retrunType1 memberFunction1(); private: dataType3 member3; dataType4 member4; retrunType2 memberFunction2(); }; customType object; // Assume member1, member2, member3 and member4 were initialized to some valid values. customType *pointerToAnObject

When I click on 'Structure' sidebar in Android Studio, it displays the contents of the current class. However there are certain icons & symbols used to indicate different members, e.g., a circle with letter m for methods, etc. Where do I get the complete list and the details for all the icons & symbols? (something like a legend/key that explains the various icons & symbols is what I'm looking for) Thanks! Follow the link below and you will get your answer about different icons and symbols in Android Studio's Structure sidebar: https://developer.android.com/tools/studio/index.html http://www

I have created a couple of different structures in a program. I now have a structure with nested structures however I cannot work out how to initialize them correctly. The structures are listed below. /***POINT STRUCTURE***/ struct Point{ float x; //x coord of point float y; //y coord of point }; /***Bounding Box STRUCTURE***/ struct BoundingBox{ Point ymax, ymin, xmax, xmin; }; /***PLAYER STRUCTURE***/ struct Player{ vector<float> x; //players xcoords vector<float> y; //players ycoords BoundingBox box; float red,green,blue; //red, green, blue colour values float r_leg, l_leg; //velocity of

I need to add a table to store user settings. For the first time users will have about 10 different settings, but I'm sure there will be more. What scalable structure of database table to store user settings would you suggest? Any help would be greatly appreciated. Thank you! Settings table columns -: setting_id | setting_code | setting_name | setting_description User table columns -: user_id | user_name | user_password | etcetera User-settings table columns -: user_setting_id | user_id_fk | setting_code_fk | setting_value structure like so: Users --> User Settings <---- Settings Hope this

I am working on turbo C on windows where char takes one byte.Now my problem is with the below union. union a { unsigned char c:2; }b; void main() { printf("%d",sizeof(b)); \\or even sizeof(union a) } This program is printing output as 2 where as union should be taking only 1 byte. Why is it so? for struct it is fine giving 1 byte but this union is working inappropriately. And one more thing how to access these bit fields. scanf("%d",&b.c); //even scanf("%x",b.c); is not working because we cannot have address for bits.So we have to use another variable like below int x; scanf("%d",&x); b.c=x;

In a project I am working on I am structuring my code as follows MyLib = { AField:0, ASubNamespace:{ AnotherField:"value", AClass:function(param) { this.classField = param; this.classFunction = function(){ // stuff } } }, AnotherClass:function(param) { this.classField = param; this.classFunction = function(){ // stuff } } } and so on like that to do stuff like: var anInstance = new MyLib.ASubNamespace.AClass("A parameter."); Is this the right way to go about achieving namespacing? Are there performance hits, and if so, how drastic? Do performance degradations stack as I nest deeper? Are there

I have this structure Data = struct('trials',{},'time',{},'theta_des',{},'vel_des',{},'trials_number',{},'sample_numbers',{}); Data(1).trials = cell(1,trials_number); for i=1:trials_number Data.trials{i} = struct('theta',{},'pos_err',{},'vel',{},'vel_err',{},'f_uparm',{},'f_forearm',{},'m_uparm',{},'m_forearm',{},... 'current',{},'total_current',{},'control_output',{},'feedback',{},'feedforward',{},'kp',{}); end but when I want to add a value Data.trials{i}.theta = 27; I get this error... A dot name structure assignment is illegal when the structure is empty. Use a subscript on the structure.

I need to find out a size of a generic structure (I can not do it like sizeof(T) or using Marshal.SizeOf(...) 0> gives me an error) So I wrote: public static class HelperMethods { static HelperMethods() { SizeOfType = createSizeOfFunc(); } public static int SizeOf<T>() { return SizeOfType(typeof(T)); } public static readonly Func<Type, int> SizeOfType = null; private static Func<Type, int> createSizeOfFunc() { var dm = new DynamicMethod("SizeOfType", typeof(int), new Type[] { typeof(Type) }); ILGenerator il = dm.GetILGenerator(); il.Emit(OpCodes.Ldarg_0); il.Emit(OpCodes.Sizeof); //needs to be
