Line 82 calc_baking_time(char bread_type, char loaf, char manual);
   }// instructions_white_single_manual

I'm trying to call the function calc_baking_time, but i don't see what else is missing?
bread.c: In function 'instructions_white_single_manual':
bread.c:82:19: error: expected expression before 'char'
bread.c:82:19: error: too few arguments to function 'calc_baking_time'
bread.c:12:8: note: declared here


i do apoligize for the lines not appearing correctly
