Counter value changes within loop when assigned to a new variable


Counter value changes within loop when assigned to a new variable

To fix the issue you can do Since there is no block scope in javascript, after both loops finish execution, the value of variable i is 5 in both cases.
However the value of the x in the second case is 4 because this is the last iteration index and i++ happens after x = i assignment.

I think the issue was by ths following , I don't have the faintest idea what the program is supposed to do (comments don't help very much, the variable names are not that descriptive). The main problem appears to be the *lenght++; statement, which bumps the pointer beyond recognition. A subsequent *length = 1; does the dirty work.
Extra comment on style: it is preferable to perform bit operations on unsigned types; sign-extention could cause '1' bits to appear at unwanted places. Also: it is advisable to use unsigned types for counters and indexes; that will cause the program to crash more rigorously on underflow.
code :
int Datasample (int *state, int *length, char *d, int *type, unsigned location, int data)
{
    int match = 1;                                  // if data sample and delayed tx match,
    int devflag = 1;        /* hoisted this variable from inner loop */
    unsigned bitpos ;     /* renamed and changed to unsigned ( location as well) */

                          /* Note: shift by zero (or negative) is undefined */
    if ( ((d[0] >> location) & 1) != data) {
        match = 0;
        if(data) type[2]++;
        else type[1]++;
    } 
                        /* Again: shift by zero is undefined */
    for( bitpos = 8; bitpos-- > 0; )                           
    {
          // find an edge
        if ( ((d[0] >> bitpos) & 1) == *state) *length += 1;
        else
        {
            int distance, deviation;
                                  // distance the edge is from the sample point. should be about 4
                                  // deviation is how far the distance then is from 4
            distance = (location > 3) ?  location - bitpos : bitpos - location;
            deviation = abs(4-distance);

            if (deviation >= devmax && match && devflag)
            {
                devflag =0;    
                if (data) type[2]++;
                else type[1]++;
            }
            *state = ((d[0] >> bitpos) & 1);
            *length = 1;
        }

    }

    return ((d[0] >> location) & 1);
}

I hope this helps you . So here's my simple C code: , I modified your code like this:
code :
void PrintText(const char txt[])
{
    if (j<i) {
        while(j<i) printf("%c",txt[j++]);
        printf("\n");
        }
}

void PrintText_StripLeft(const char txt[])
{
    for (; (j < i) && (32 == txt[j]); ++j);
    PrintText(txt);
}
for(i; i<strlen(txt); i++){
    if(txt[i] == 32) k=i;
    if(i!=0 && (i-j)%limit == 0){
        if(txt[i] != 32 && k){i=k;k=0;}
        PrintText_StripLeft(txt);
        }
    }

PrintText_StripLeft(txt);

To fix this issue In your while loop you are looping over the HTTP headers and the data line by line and overwrite deviceToken each time. This is ok, except that each line ends with \r\n and not only \r - (also, you probably only want to write the token to the eeprom, not every header).
So the last token that gets read is a single \n which is then put into deviceToken. You will need to read that extra byte after each line.

wish helps you Here's my current code snippet: , Like this?
code :
Iterable<HashMap<String, EntityProperty>> results =
        cloudTable.execute(query, propertyResolver);

int counter;
if (results == null) {
    System.out.println("No files processed");
    exit_code = "exit_code=1";
} else {
    counter = 0;
    for (HashMap<String, EntityProperty> entity : results) {
        // don't know how to start the loop here 
        counter++;
    }
    //int size = results.size();
}

To fix the issue you can do C# needs variables to be definitely assigned. Meaning, variables must been set with an initial value before you it can be read.
