Xcode error

Hi! I am following along with the Pointer Power video and Xcode is giving me errors and not sure why... this is my code (identical to the video, as far as I can tell):

int main() { char *letter;

char c = 'k';

letter = &c;
printf("%c is always the same as %c\n", c, *letter);

char c = 'q';
printf("%c is always the same as %c\n", c, *letter);

char c = 'x';
printf("%c is always the same as %c\n", c, *letter);

return 0;

}

when I ask Xcode to run, I get a "build failed" and a red error message that says "redefinition of 'c'". unsure of how to proceed, any help appreciated! thank you!

try using 

char *letter;

char c = 'k';

letter = &c;
printf("%c is always the same as %c\n", c, *letter);

 c = 'q';
printf("%c is always the same as %c\n", c, *letter);

 c = 'x';
printf("%c is always the same as %c\n", c, *letter);

return 0;

instead. you only need to declare c as a char once, you can just reference it as c after that
