My phase looks like this :
enum Gait_cycle_states {
HEEL_STRIKE,
FLAT_FOOT,
MID_STANCE,
HEEL_OFF,
TOE_OFF,
MID_SWING
};
My struct looks like this :
struct State {
Gait_cycle_states current_state;
uint8_t next_state; //index of the next state
uint8_t ay_num_criteria;
State_criterion *ay_criteria_for_state;
unsigned int gy_num_criteria;
State_criterion *gy_criteria_for_state;
};
and my function looks like this :
void initialize_FSM(State states_array[]){
//Heel strike----------------------------------------------------------
State heel_strike = {
.current_state = HEEL_STRIKE,
.next_state = 1, //the index of the next state
.ay_num_criteria = 1,
.ay_criteria_for_state = new State_criterion[1],
.gy_num_criteria = 2,
.gy_criteria_for_state = new State_criterion[2]
};
//The features to look for in accel_y and gyro_y, and how old they can be to count (in ms)
heel_strike.ay_criteria_for_state[0] = { NO_FEATURE, 150 };
heel_strike.gy_criteria_for_state[0] = { NEGATIVE_TROUGH, 150 };
heel_strike.gy_criteria_for_state[1] = { BREACHED_HIGH_THRESHOLD, 30 };
//putting the state we just configured into the state array
states_array[0] = heel_strike;
};
It seems Visual studio 2015 is not letting me assign the value to my types using "." or in the fashion, I am doing it.
It is throwing me a bunch or error and warnings like this :

could someone please suggest me what could be done?
State heel_strike = {
HEEL_STRIKE,
1, //the index of the next state
1,
new State_criterion[1],
2,
new State_criterion[2]
};
What you are trying to use is known as "designated initializers". They are a feature of C language (since C99), not part of standard C++. Some compilers support it for C++ as an extension, but MSVC does not.

Doesn't look like it was parced correctly even. But it looks fine to me.
Maybe it doesn't like newlines? Tried without them.
Maybe it must be in UPPER CASE? I honestly have no idea.
Maybe it doesn't like ////comments?

It looks like your post is mostly code, please add some more details.
Here is how I use it:
float* p = (float*)malloc(999);
fill(i_im_x, i_im_x + 512.0f,
i_im_y, i_im_y + 512.0f,
0.0f, 1.0f,
0.0f, 1.0f);
You need to do this:
Replace all ////xx comments by /* xx */
Remove the stray space character after the \ in following line:
*p++ = where_l; \
^ stray space here
This was not obvious because you cannot see that stray space unless you put the cursor there.
Remove the final \ in the very last line of the macro:
*p++ = what_b; \
^ remove this
Working example:
#define fill(where_l, where_r, where_t, where_b, what_l, what_r, what_t, what_b) \
\
/*lt*/ \
*p++ = where_l; \
*p++ = where_t; \
*p++ = 0.5f; \
*p++ = 1.0f; \
*p++ = what_l; \
*p++ = what_t; \
\
/* rt */ \
*p++ = where_r; \
*p++ = where_t; \
*p++ = 0.5f; \
*p++ = 1.0f; \
*p++ = what_r; \
*p++ = what_t; \
\
/*lb*/ \
*p++ = where_l; \
*p++ = where_b; \
*p++ = 0.5f; \
*p++ = 1.0f; \
*p++ = what_l; \
*p++ = what_b; \
\
/*rb*/ \
*p++ = where_r; \
*p++ = where_b; \
*p++ = 0.5f; \
*p++ = 1.0f; \
*p++ = what_r; \
*p++ = what_b;
int main(int argc, char **argv) {
float* p = (float*)malloc(999);
fill(1, 2, 3, 4, 5, 6, 7, 8)
}
I am making a program to simulate a game show, randomly. The program picks 1 of three doors for the prize to be hidden behind randomly. The computer picks a door to see if it won or not. This is looped over 10000 times to see how many times I win if I change my pick versus not changing it.
I am getting a bunch of syntax
#include <path-spec>
#include <stdio.h>
#include <time.h>
void count(Status result, Door* pLast_pick, Door* pPick, int* pWin_unchanged, int* pWin_changed);
void randomize_door(Door* pJackpot);
void pick_door(Door* pPick);
Status check(Door* pPick, Door* pJackpot);
enum status {WIN=1,LOSE};
enum door { FIRST=1, SECOND, THIRD };
typedef enum door Door;
typedef enum status Status;
int main(int argc, char* argv[]){
int i = 0;
srand(time);
Status result;
Status* pResult = &result ;
Door jackpot, pick, last_pick=NULL;
Door* pJackpot = &jackpot, * pPick=&pick, *pLast_pick;
int win_unchanged = 0, win_changed=0;
int* pWin_unchanged = &win_unchanged, *pWin_changed=&win_changed;
while (i < 10000){
last_pick = NULL;
randomize_door(pJackpot);
pick_door(pPick);
result = check(pPick, pJackpot);
count(result, pLast_pick, pPick, pWin_unchanged, pWin_changed);
i++;
}
printf("Wins when changed choice: %d , wins when choice is unchanged: %d", win_changed, win_unchanged);
return 0;
}
void randomize_door(Door* pJackpot){
*pJackpot = rand() % 3 + 1;
}
void pick_door(Door* pPick){
*pPick = rand() % 3 + 1;
}
Status check(Door* pPick, Door* pJackpot){
if (*pPick == *pJackpot){
return WIN;
}
else{
return LOSE;
}
}
void count(Status result, Door* pLast_pick, Door* pPick, int* pWin_unchanged, int* pWin_changed) {
if (*pLast_pick == *pPick){
if (result == WIN){
*pWin_unchanged++;
}
}
else{
if (result == WIN){
*pWin_changed++;
}
}
*pLast_pick = *pPick;
}
Below are the errors and which lines its happening at. most of them are forgot } or ; which doesn't make any sense in a function header.

C99 support added visual studio 2013, but I cant use complex.h in my "C" code.
#include <stdio.h>
#include <complex.h>
int main(void)
{
double complex dc1 = 3 + 2 * I;
double complex dc2 = 4 + 5 * I;
double complex result;
result = dc1 + dc2;
printf(" ??? \n", result);
return 0;
}
I get syntax errors.
Edit: Sorry for the missing part.

In case anyone is searching a year later, try
_Dcomplex dc1 = {3.0, 2.0};
for the variable declaration.
From looking inside VS2013's "complex.h" header, it seems that Microsoft decided on their own implementation for C complex numbers. You'll have to implement your own arithmetical operators using the real() and imag() functions, i.e.:
double real_part = real(dc1) + real(dc2);
double imag_part = imag(dc1) + imag(dc2);
_Dcomplex result = {real_part, imag_part};
Another way is to define like:
/*_Fcomplex */ _C_float_complex a = _FCbuild(5.0F, 1.0F);
printf( "z = %.1f% + .1fi\n", crealf(a), cimagf(a));
/*_Dcomplex*/ _C_double_complex b = _Cbuild(3.0, 2.0);
printf("z = %.1f% + .1fi\n",creal(b), cimag(b));
I'm writing an application in ANSI C (Visual Studio 2010)
my library looks like this:
#include <stdio.h>
#include <stdlib.h>
#ifndef _MYLIB_
#define _MYLIB_
typedef enum {false, true} bool;
// some structures and function prototypes...
#endif
I include this library in every .c file (I've got like 4 .c files - 1 main.c with main() and the rest with functions).
I get an error:

What's more - when I paste all functions and structures into main.c - it works properly...
I have no idea how to fix it...
I strongly believe that you are interfering with the C++ built-in false and true, so you are trying to redefine them in your enum.
Try to replace false and true with FALSE and TRUE and bool with BOOL.
#include <stdio.h>
#include <stdlib.h>
#ifndef _MYLIB_
#define _MYLIB_
typedef enum {FALSE, TRUE} BOOL;
// some structures and function prototypes...
#endif
This code is working fine in c++.I need the solution for C.
This is my sample.
FileName:Mail.c
This is the declaration I made in the file mail.c
#ifdef __cplusplus
typedef int (__cdecl *SetIpAddressFun)(char* , int , int );
typedef bool (__cdecl *SendMailFun)(char * , char *);
#endif
I used this function pointers in the function called func() in the same file mail.c
void func()
{
SendMailFun sendMailFuncPtr;
SetIpAddressFun setIpAddressFuncPtr;
}
EDIT
If i remove the #ifdef lines in the file mail.c then it is showing the following error.

This is because when you declared the function
#ifdef __cplusplus
typedef int (__cdecl *SetIpAddressFun)(char* , int , int );
typedef bool (__cdecl *SendMailFun)(char * , char *);
#endif
you do it conditionally only for __cplusplus which is typically not defined when compiling C files
EDIT
I think your second problem is to do with the presence of bool which to my knowledge is not C keyword. Considering replacing it with an int
The #ifdef __cplusplus means that bit of code will only be complied when using a C++ compiler.
It's the bit that defines the function pointer type SendMailFun, so the compiler errors are complaining that SendMailFun and SendMailFun don’t exist.
You could start by removing the lines
#ifdef __cplusplus
and
#endif
