Compare Strings in C

Question

OMG, I know this should be extremely simple and I have tried everything I have researched but nothing works. I am missing something simple, please help. I just want to declare a string and then later compare it to another string.

I want to declare a key of something like 9 characters. Then I want to compare this string to another one submitted later. Below is what I have and no matter what I change I get errors from incompatible types to missing token.

char key[] ="kjherres";
char f[];

F="kjherres";    

if (key==f) {
 //run my code
}

I have also tried (strcmp) to no avail. What am I missing? Please help.

Answer 1

The way you compare strings is with the strcmp function.

if ( strcmp(key,f) == 0 ) {
    /* strings are the same */
}

You should have a good book or online tutorial to learning C. If you're coming from PHP or some other high-level language, you have a LOT to learn and if you don't do it right, you're asking for big problems. Strings are not as trivial in C as they are in PHP etc.

Also, C is case-sensitive. F and f are different names.

Answer 2

OK, this was a stupid thing I missed as always. Sometimes my mind is going faster than my fingers.

What the problem was is that I assigned f from a url param but I was only reading the first char of the param. Forgive me for the ignorance, it can happen often when going too fast.
