Arrays

I have tried writing the program exactly as it is in the video, but I keep getting an error and a warning on my build with the following statement:

int primes[] = (2, 3, 5, 7);
printf("the first 4 prime numbers %d %d %d %d\n", primes[0], primes[1], primes[2], primes[3]);

Here is the warning: /Users/vincentweimer/Documents/Development/Anatomy of C/Arrays/MyFirstCProgram/main.c:23:27: Expression result unused

Here is the warning: /Users/vincentweimer/Documents/Development/Anatomy of C/Arrays/MyFirstCProgram/main.c:23:9: Array initializer must be an initializer list or wide string literal

Any thoughts?

C arrays need to be initialized with { } around the values, not ( )

int primes[] = {2, 3, 5, 7};
printf("the first 4 prime numbers %d %d %d %d\n", primes[0], primes[1], primes[2], primes[3]);

Gotcha. Guess that is what I get for coding without my glasses on. Thanks for the help!
