I lost my rant :(

I logged in, started a new topic ranting about my life's programming experience and how difficult it was because I have a learning disability that prevents me from actually learning C. I hit preview and it sent me to the login screen losing my post. So you get the scaled way back version. I have to relearn how to do things in C every time I set down to write code. Initialization code is most difficult because it can be quite esoteric. The problem for me is not finishing it in one day. The next day I often look at the code and wonder who wrote it. I just did not remember writing it or how it was supposed to work. So I had to start over. Today I was able to simplify the code so I could write it in one day. It took me about 8 hours to complete. The code is the initializing of a move lookup table--just the bishop as it had to be a 'small task' if I were to finish it before bed.

Code: Select all

``````typedef struct {
int ts;
int ns;
int nd;
} mt;

mt m[10000];

void InitMovTbl();
void Initialize();
int main();

void InitMovTbl() {
int sq, ns, y, x, dy, dx, o, p, i;

for (sq = ns = 0; sq < 64; sq++) {
y = sq >> 3;
x = sq & 7;

for (p = ns, dy = 1, dx = -1; y + dy < 8 && x + dx > -1; dy++, dx--) {
o = p;
m[ns].ts = sq + (dy << 3) + dx;
m[ns].ns = ns + 1; ns++;
} for (i = p; i < ns; i++) m[i].nd = ns;

for (p = ns, dy = 1, dx = 1; y + dy < 8 && x + dx < 8; dy++, dx++) {
o = p;
m[ns].ts = sq + (dy << 3) + dx;
m[ns].ns = ns + 1; ns++;
} for (i = p; i < ns; i++) m[i].nd = ns;

for (p = ns, dy = -1, dx = -1; y + dy > -1 && x + dx > -1; dy--, dx--) {
o = p;
m[ns].ts = sq + (dy << 3) + dx;
m[ns].ns = ns + 1; ns++;
} for (i = p; i < ns; i++) m[i].nd = ns;

for (p = ns, dy = -1, dx = 1; y + dy > -1 && x + dx < 8; dy--, dx++) {
o = p;
m[ns].ts = sq +  (dy << 3) + dx;
m[ns].ns = ns + 1;
m[ns].ns = 0; ns++;
} for (i = p; i < ns; i++) m[i].nd = ns;

m[ns - 1].ns = 0;
for (i = o; i < ns; i++) m[i].nd = 0;
}

}

void Initialize() {
InitMovTbl();
}

int main() {
Initialize();
}

I hate if statements. Pawns demand if statements. Therefore I hate pawns.

Yes, this used to happen to me as well. It taught me to always copy the whole post to the clipboard before previewing/posting.

never happened to me in this forum but the in a different forum when it happened there were cases when I could return back to the previous screen so I did not lose my post.

I recommend additionally saving what you write to the file (if the text is very large). Then just don't lose what you write.

Re: I lost my rant :(

Part of the problem is your coding style. Your function names are OK, but your variable names are not informative at all. I have no idea what `ts', `ns', `nd', `mt', or `m' mean. Chances are you won't know when you encounter the code in a couple of days either. You should write code that is easy for a human to read. Getting the compiler to understand you is the easy part, but that's not good enough.
