How can I preserve the assign order in a structure in ColdFusion <2016

问题 ColdFusion doesn't preserve the order in which elements were assigned to the structure. This gives a problem when, in my particular case, I need to create a SOAP envelope from this structure and the receiver needs to data in the envelope in a particular order. Starting from ColdFusion 2016 and higher, there is a "type" option in the StructNew() method where you can specify "Ordered". Unfortunately, I'm still on CF9.02... For example (in CF9): <cfscript> myStruct=StructNew(); myStruct.one

Unlogical C6001 warning: Using uninitialized memory warning in C with Visual Studio

问题 Given this code: #include <stdlib.h> typedef struct { int *p; } MyStruct; MyStruct Test() { MyStruct ms; ms.p = malloc(sizeof(int) * 5); if (!ms.p) exit(-1); return ms; } int main(void) { while (1) { MyStruct t = Test(); free(t.p); // C6001: Using uninitialized memory 't.p'. } } Visual Studio shows C6001 warning on the free call line. However, I see there is no way to achieve the free line with the memory t.p uninitialized. What am I missing ? 回答1: Some points: sometimes SAL warnings can be

C Compile Error: array type has incomplete element type

问题 #include <stdio.h> typedef struct { int num ; } NUMBER ; int main(void) { struct NUMBER array[99999]; return 0; } I'm getting a compile error: error: array type has incomplete element type I believe the problem is that I'm declaring the array of struct incorrectly. It seems like that's how you declare it when I looked it up. 回答1: struct NUMBER array[99999]; should be NUMBER array[99999]; because you already typedef ed your struct. EDIT: As OP is claiming that what I suggested him is not

Nested structure in c

问题 I have to build a nested structure to store some basic information about some person (name, age, address). So I created a structure called "info" and to hold the address I created another nested structure inside "info" called "address". But whenever I prompt to store the values using a for loop, I get errors. What is the problem here and how can I solve it? [Error] 'struct Info' has no member named 'address' [Warning] declaration does not declare anything [enabled by default] #include <stdio

How to interpret address_space struct in `# define __percpu __attribute__((noderef, address_space(3)))`

问题 I am looking scheduling algorithm in static void __sched notrace __schedule(bool preempt) (__schedule) Along the way, I find # define __percpu __attribute__((noderef, address_space(3))) (address_space) However, I cannot understand why struct address_space can be initialized by using round brackets ( ) since I look through struct syntax in c language. How to initialize a struct in accordance with C programming language standards. struct should be initialized by { } for each filed. So, what

How to store data from pointer returned by strtok into struct without it being lost?

时光怂恿深爱的人放手 提交于 2021-02-08 10:25:56
问题 I have a malloced string that I needed to parse. I did all of the parsing using strtok() . Strtok has returned a pointer to me and if I printf using that pointer the correct part of the parsed string gets printed. Afterwards I will be freeing the malloced string that the pointer returned by strtok was pointing too. How do I store what the pointer was pointing at into a struct such that the value remains in the struct variable even after the main string has been freed. String: Tommy-1234567 My
