strcmp()

hi, im using strcmp to compare a character pointer char *cptr with a character array
char text[100] using if(strcmp(cptr, text)==0) printf("%s", cptr);

my debugger shows this....

cptr = 0x0012F028 "orange" char*
text "orange" char[]

the result of strcmp(cptr, text)==0 will always be false... why?

Are both arrays null terminated?

show code where you initialize both strings

i used strtok to get 2 string whereby each string is seperated by SPACE. then i compare them using strcmp. is dat wat causes the error because using strtok removes the "\n" ? if so how do i actually compare the string?

show the code instead of your interpretation what is going on...
Small compileable samle representing the problem

check out the strcmp at the last while loop

Code:

---

if(strcmp(currNode->words, ptr ))

You're missing the comparison to 0.... the one that you told us you were doing.

even if i put if(strcmp(currNode->words, ptr ) == 0) still return false when my input is shown below is being compared

name, value, type

currNode->words, 0x003a1d30 "orange", char *
ptr, 0x0012fe78 "orange", char *

and what about sample file you are reading?
I suppose the problem is '\n' char you do not remove so one string contains it and another - does not...

hmmm i dun understand. which part did i removed the \n? isit the strtok ?

if one string is
"orange apple\n"
and second
"apple orange\n"

with your strtok approach you finish with comparing

"orange" to "orange\n"
and "apple\n" to "apple"

both comparisomns will fail

no wonder.. one of my text file is like and essay and the other is one word per line...
so.. any advise on how to solve the problem or is there other way to compare the string without using strcmp?

yea i already fixed that. now its jus only the strcmp issue :(

Read the last post, I've already attempted to sort some of your issues out.

You obviously haven't done what I've suggested.

Thanks for the advice everyone, i manage to solve it
