structure

问题 My structure definition is, typedef struct { int taxid; int geneid; char goid[20]; char evidence[4]; char qualifier[20]; char goterm[50]; char pubmed; char category[20]; } gene2go; I have tab-seperated text file called `"gene2go.txt". Each line of this file contains taxID , geneID , goID , evidence , qualifier , goterm , pubmed and category information. Each line of the file will be kept in a structure. When the program is run, it will first read the content of the input file into an array of

问题 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! 回答1: Follow the link below and you will get your answer about different icons and

问题 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

问题 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

问题 can any one tell me how to convert the string content into X509 structure . i am using openssl to read the X509 Structure. example : certificate string -----BEGIN CERTIFICATE----- MIIExDCCA6ygAwIBAgIJAK0JmDc/YXWsMA0GCSqGSIb3DQEBBQUAMIGcMQswCQYD VQQGEwJJTjELMAkGA1UECBMCQVAxDDAKBgNVBAcTA0hZRDEZMBcGA1UEChMQUm9j a3dlbGwgY29sbGluczEcMBoGA1UECxMTSW5kaWEgRGVzaWduIENlbnRlcjEOMAwG A1UEAxMFSU1BQ1MxKTAnBgkqhkiG9w0BCQEWGmJyYWphbkBSb2Nrd2VsbGNvbGxp

问题 For a simulation program I'm working in Delphi 2010. The simulation isn't a problem but I need to use large collection of data which gives a problem. The data is available in excel sheets, so there is no need to edit this data in Delphi, but collecting this data from the excel sheets takes around 10min. This isn't a problem as long as you don't need to collect the data every time the program runs. So I made a program which collects all the data makes it visible, not problems here,and then

问题 Structure 1: typedef struct _wfs_cdm_cu_info { USHORT usTellerID; USHORT usCount; LPWFSCDMCASHUNIT * lppList; } WFSCDMCUINFO, * LPWFSCDMCUINFO; Structure 2: typedef struct _wfs_cdm_cashunit { USHORT usNumber; USHORT usType; LPSTR lpszCashUnitName; CHAR cUnitID[5]; CHAR cCurrencyID[3]; ULONG ulValues; ULONG ulInitialCount; ULONG ulCount; ULONG ulRejectCount; ULONG ulMinimum; ULONG ulMaximum; BOOL bAppLock; USHORT usStatus; USHORT usNumPhysicalCUs; LPWFSCDMPHCU * lppPhysical; } WFSCDMCASHUNIT,

问题 I am trying to find out how (using a quicksort algorithm) to sort an struct array by 2 criterias. For example say I had a struct of: struct employee{ char gender[12]; char name[12]; int id; }; Say my input is: struct employee arr[3]= { {"male","Matt",1234}, {"female","Jessica",2345}, {"male","Josh",1235} }; I am wanting to sort the elements by gender first then the IDs in ascending order. An example would be have all the males printed first with their IDs in order and then all the females

问题 I want to count the number of members in a structure. For example: typedef struct { char MrChar; int MrInt; long MrLong; } Bg_Typedef; Bg_Typedef FooStr; I create a function prototype that should return number of members in the structure int NumberOfMem(Bg_Typedef *psStructure); => NumberOfMem(&FooStr) should return 3 回答1: It can be done with X_MACRO's. Do something like this: #define X_BG_MEMBERS \ X(char, MrChar) \ X(int, MrInt) \ X(long, MrLong) typedef struct { #define X(type, member)

问题 I have used bit field with a structure like this, struct { unsigned int is_static: 1; unsigned int is_extern: 1; unsigned int is_auto: 1; } flags; Now i wondered to see if this can be done with a union so i modified the code like, union { unsigned int is_static: 1; unsigned int is_extern: 1; unsigned int is_auto: 1; } flags; I found the bit field with union works but all those fields in the union are given to a single bit as I understood from output. Now I am seeing it is not erroneous to use
