Shit in C

I'm trying to set the contents of a string based on what random number is generated by my srand.

dice = rand() % 10 + 1;

if ( dice = 1 )
word[20] = "Success";

^-- this shit doesn't work, though.

tl;dr. I want my "dice rolls" to generate a random number, random number corresponds to a pre-set word, and the preset word to be printed.

I'm probably going about it the wrong way. Suggestions from experts?

6. Compilers often give more memory to arrays than you asked for. Here's how to check how big an array actually is (memset returns a null pointer if the size you passed to it is bigger than the size of the array you passed to it):
int arr[256];
size_t realsize;
for (realsize = 0; realsize <= SIZE_MAX; ++realsize)
        if (!memset(arr, 0, realsize)) break;
/* now you know that arr actually has realsize / sizeof (int) elements */
If you combine this with #5, your program will be faster in the long run (but this usually doesn't work for short programs).
