Int changing value for no reason at runtime.....

[jaredgalen]

I'm new to C, today being my first day really.
Here's the prob:

BYTE indexes[11]; <-- putting ints between zero and 4096 into this array.
In one hand I have a variable X.
I'm looking at indexes[0], I want to I push everything down and put X in at indexes[0].

However, somehow X is getting changed.

Before reordering - Inserting X=3236 <-variable X
225 161 98 164 225 161 100 96 37 36 33

X=164<- variable X has changed to this, somehow

After reordering
164 225 161 98 164 225 161 100 96 37 36

164 is what indexes[0] contains now, it should be 3236.

Should I be using pointers or something?? I really haven't a clue, this whole 'C' thing is very confusing.
What am I missing or have a made a really silly mistake that I just can't see....

Here's the bit of source that corresponds to this, there is only a print statement between...
The code is really crappy I know, I don't really know any major functions so it's very basic.

for(i=0;i<4096;i++)
{
if(keyCounter>largestKeyCount)
{
printf(&quot;\nBefore reordering - Inserting &quot;
printf(&quot;%d&quot;,i);
printf(&quot;\n&quot;
for(j=0;j<11;j++)
{
!!XXXX Here it has the right value XXX!!
printf(&quot;%d&quot;,indexes[j]);
printf(&quot; &quot;
}

tempIndex1 = indexes[0];
indexes[0] = i;
printf(&quot;\n&quot;<-!!XXXX Here it has changed XXXX!!
printf(&quot;%d&quot;,indexes[0]);
for(j=1;j<11;j++)
{
tempIndex2 = indexes[j];
indexes[j] = tempIndex1;
tempIndex1 = tempIndex2;
}
printf(&quot;\nAfter reordering\n&quot;
for(j=0;j<11;j++)
{
printf(&quot;%d&quot;,indexes[j]);
printf(&quot; &quot;
}
}
Hope someone can help me.
Thanks

the size of a byte is 8 bits. That is a value from 0-255. Change your array type to short or int.

Oh for the love of god......
I feel like a right goon.

It has happened to the best of us :-D Sometimes it just requires a second pair of eyes. The one that used to bite me in the butt was assigning instead of comparing in if statements.

if(value = <some value other then zero>)
