Hi all!
I'm having a trouble to exclude (substitute with the next string) repeated strings from an array:
But this code don't work properly. Mainly if the rptds[x] > rptds[x+1]Code:char hst[30][30]; /* stored strings */
int qt_hst; /* amount of strings at hst */
int rptds[10]; /* store which lines numbers are repeated strings */
int a, b;
...
a = b = 0;
while (b = rptds[a])
{
for (b; b<=qt_hst; b++)
strcpy(hst[b-a], hst[b-a+1]);
a++; qt_hst--;
}
> while (b = rptds[a])
Should probably be: while (b == rptds [a])
> b<=qt_hst
You realise that arrays have first index being 0, so perhaps it should be b < qt_st?
> strcpy(hst[b-a], hst[b-a+1]);
You could do a little debugging by printing the values of b-a and b-a+1 and then check if those values are not above 30, which is the maximum number of stored strings.
>> while (b = rptds[a])

no. is really b = rptds[a]
> b<=qt_hst
You realise that arrays have first index being 0, so perhaps it should be b < qt_st?
the counter also starts on 0.

I already did. I couldn't find the bug.
Please, let me know if someone have a solution for this code.
