Character Array Complement

I would write a complement() function.
Use switch-case syntax could help here

char DNA_complement(char base)
{
   switch (base) {
     case 'A':
       return 'T';
     case 'G':
       return 'C';
     case 'T':
       return 'A';
     case 'C':
       return 'G';
   }
   // might also want to handle some error if it's not A,G,T, or C.
}

And then you would call complement() inside a for loop that goes through each character.

This tutorial talks about control statements and loops:
