Finding unique elements in an string array in C

Question

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 = da

Think a bit more about your problem -- what you really want to do is look at the PREVIOUS strings to see if you've already seen it. So, for each string n, compare it to strings 0 through n-1.

print element 0 (it is unique)
for i = 1 to n
  unique = 1
  for j = 0 to i-1 (compare this element to the ones preceding it)
    if element[i] == element[j]
       unique = 0
       break from loop
  if unique, print element i
