C/C++ :: Testing String Against Array Of Char

I have a text file with state names, and state abbreviations, thusly:

ALASKA
AK
ARKANSAS
AR
..and so on.

I have to load the abbreviations ONLY from the file into an array of char[ - (already done and tested).

I have to get a 2 char abbreviation as a string,then test it against the state array to make sure it is a valid abbreviation. As it stands, my test is never finding an invalid abbreviation..

Here is where I get the input:

void getState() {
char state[10];
getString("Please enter the state as a 2 char abbreviation:",state,10);
printf("State Entered:%s", state);
validState(state);

[Code] ....
