I'm working on the check() part of dictionary.c. I wanted to use strcasecmp() to compare the text word and the word in my dictionary. Nevertheless, it doesn't work. It keeps pop up the error :
dictionary.c:115:19: error: implicit declaration of function 'strcasecmp' is invalid in C99 [-Werror,-Wimplicit-function-declaration] result = strcasecmp(cursor,word);
Then, I used the sandbox to test code with strcasecmp(), and there is a weird bug.
I believe these two codes are 100% identical, but the one with the comment is able to compile, while the one without comment can't compile. And it's the same error with the code in my dictionary.c
