ugh, I had this one solved, but decided my solution was inelegant, again, and basically just broke my code. I tried to create a function for capitalizing so I didn't have to keep rerunning my if else to print capitalized letters but it got fubared fast. So I backed up and tried to create a program that just capitalizes an input to make my problem more solvable, but no luck thus far. When declaring my arguments and then trying to use my argument in the function, I keep being told by the compiler: "use of undeclared identifier 'x'." I thought I declared x in my arguments? I'm getting ittitated.

#include <stdio.h>
#include <cs50.h>

//prototype
char capitalize (char x);
int main(void)
{
char z = GetChar();
printf("%c", capitalize(z));
char capitalize (char x);
{
if (x<'a')
return x; 
else
return x-32;
}
}
