I've created an array of structs but I'm getting the error written on the title of this question. I'm still new to this so I was wondering if I could get some help.
Code:
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
lcd.begin(16, 2);
i = 0;
}
#define LIMIT 27
struct protocol {
char create[16];
char character;
int values;
int minimum;
int maximum;
};
struct protocol channels[LIMIT];
int i;
void create_channels() {
if (Serial.available() > 0) {
Serial.print("Enter the channel description");
channels[i].create = Serial.read();
Serial.print("Enter the starting character: ");
channels[i].character = Serial.read();
if (i == LIMIT) {
for (i = 0; i < LIMIT; i++)
{
Serial.println(channels[i].create);
Serial.println(channels[i].character);
}
i = 0;
}
}
}
Error:
cw.ino:24:38: error: incompatible types in assignment of 'int' to 'char [16]'
channels[i].create = Serial.read();

The error is generated in this part of the code and precisely here:
writeVal[j] = RBF1[i+1];
I am attaching the code:

I tried to generate a new, simpler project by inserting only the code I entered above and I don't get any errors. At this point I have always added on the new project through CubeIDE FILEX, THREADX and SDMMC1 the latter generates the same error written above. For FILEX, THREADX and SDMMC1 the code is only the one generated by CubeIDE.
I am trying to transfer the elements from a source stack to a destination stack. And for that i am using some variables and making sure that get transfered into the destination stack in the same order as they were in the source stack. I wrote the following code
#include <iostream>
#include <stack>
using namespace std;
template <typename S>
void transferByVar(stack<S> &source, stack<S> &dest)
{
int var = 0;
S topVal;
if (source.empty())
return;
else if (source.size() == 1)
{
dest.push(source.top());
source.pop();
}
int size = source.size();
while (count != size)
{
topVal = source.top();
source.pop();
while (source.size() != count)
{
dest.push(source.top());
source.pop();
}
source.push(topVal);
while (!dest.empty())
{
source.push(dest.top());
dest.pop();
}
++count;
}
}
int main()
{
stack <int> s1;
stack<int> s2;
s1.push(0);
s1.push(1);
s1.push(2);
s1.push(3);
s1.push(4);
s1.push(5);
s1.push(6);
s1.push(7);
s1.push(8);
s1.push(9);
transferByVar(s1, s2);
int size = s2.size();
for (int i = 0; i < size; i++)
{
cout << s2.top() << " ";
s2.pop();
}
return 0;
}
but it gives me an error of C2563: mismatch of formal parameter list. What can I do to fix this?
I am having debug assertion error as soon as I input two elements. The program was giving me access reading or sometimes writing violation error after taking 7-8 entries but after I deleted the dynamic array, it is showing debug assertion failed after taking first two inputs and breaks down. Any idea for how to solve it? I am copying only my air class here. I have similar Fire, earth and water classes too.
The error is BLOCK_TYPE_IS_VALID (pHead->nBlockUse)
Someone else too asked this question but i can't figure out My program errors. Kindly help would be appreciated.

BLOCK_TYPE_IS_VALID (pHead->nBlockUse)
Assertion means a corrupt heap at deleting/clearing.
As far as I see, you missed the virtual deconstructor of Element.
Try something like:
virtual ~Element() {}
in class Element.
And please post also the Element class.
Good luck!
I'm trying to compile a code in Visual Studio, but I keep getting the following error:

You will have to use gcroot See http://msdn.microsoft.com/en-us/library/481fa11f.aspx
struct nativeMindSetFormHandle
{
nativeMindSetFormHandle(MindSet::Form1 ^ h) : handle(h) {}
gcroot<MindSet::Form1 ^> handle;
};
static void handleDataValueFuncProxy(unsigned char extendedCodeLevel,
unsigned char code, unsigned char valueLength, const unsigned char *value,
void *customData)
{
static_cast<nativeMindSetFormHandle *>(customData)->handle->handleDataValueFunc(extendedCodeLevel, code, valueLength, value, NULL);
}
And update IniciarCaptura_Click to include:
nativeMindSetFromHandle * nativeHandle = new nativeMindSetFormHandle(this);
THINKGEAR_initParser(&parser, PARSER_TYPE_PACKETS, handleDataValueFuncProxy, nativeHandle);
And don't forget to delete nativeHandle when you are done.
While working in client-server programming, I have passed 3 strings in client, which will be received by server and it should be printed in there 3 times. (i.e I have used a 'for' loop which will do the read & write operations in client & server side respectively.), but in server only the 1st string is getting printed.
Please explain,
Here is my code
server.c
#include "head.h"
void readstr(int connfd ,char [][20]);
//void writestr(char * ,int);
int main(int c ,char *v[])
{
// socket declarations,etc
sd =socket( AF_INET ,SOCK_STREAM ,0);
// Binding socket
retbind =bind(sd ,(struct sockaddr*)&serveraddress ,sizeof(serveraddress
));
listen(sd ,4);
for(;;)
{
printf("i am waiting for client\n");
len =sizeof(cliaddr);
connfd = accept(sd ,(struct sockaddr*)&cliaddr ,&len);
readstr(connfd ,databuf);
close(connfd);
}
return 0;
}
void readstr(int connfd ,char str[3] [20])
{
int pointer=0 ,i=0, n,pos=0;
memset(str ,'\0',sizeof(str));
for(i=0;i<3;i++)
{
while((n=read(connfd ,str[i] ,20)) >>0)
{
printf("Looping while\n");
pos =pos +n;
}
str[i][pos] ='\0';
}
for(i=0;i<3;i++)
{
printf("\n%s",str[i]);
}
}
client.c
#include "head.h"
void send1(int ,char*);
int main(int c,char*v[])
{
//Socket declarations, etc..
sd = socket(AF_INET ,SOCK_STREAM ,0);
//Connect
if(connect(sd,(struct sockaddr*)&serveraddress ,sizeof(serveraddress)) <
0)
{
printf("cannot connect to server");
exit(1);
}
for(i=0;i<3;i++)
{
memset(buf ,'\0',sizeof(buf));
printf("\n Enter the string : ");
fgets(buf[i],20,stdin);
len =strlen(buf[i]);
if(buf[i][len] =='\n')
buf[i][len]='\0';
send1(sd ,(char *)buf);
}
shutdown(sd ,SHUT_WR);
}
void send1(int sd ,char *str)
{
int n ,byteswritten =0, wr;
char buf[1024];
strcpy(buf ,str);
n =strlen(buf);
while(byteswritten < n)
{
printf("\nStarting to write in client side\n");
wr = write(sd , buf+byteswritten ,(n-byteswritten));
byteswritten+=wr;
}
printf("\n string sent %s" ,buf);
}
In server.c in readstr() you are not setting pos to zero before the next for iteration.
Also, there is strange line:
while((n=read(connfd ,str[i] ,20)) >>0)
Note ">>".
