Finding unique elements in an string array in C
- by LuckySlevin
Hi,
C bothers me with its handling of strings. I have a pseudocode like this in my mind:
char *data[20];
char *tmp; int i,j;
for(i=0;i<20;i++) {
tmp = data[i];
for(j=1;j<20;j++)
{ if(strcmp(tmp,data[j]))//then except
the uniqueness, store them in
elsewhere. } }
But when i coded this the results were bad.(I handled all the memory stuff,little things etc.) The problem is in the second loop obviously :D. But i cannot think any solution. How do i find unique strings in an array.
Example input : abc def abe abc def deg entered
unique ones : abc def abe deg should be found.
