Yes or No decision problem

hi guys! i'm kinda new programming , need help.



keep getting "exc_bad_access" every time enter "y"

code:

  take bmi using meters(height) &   kilograms(weight)? (y/n): y  current language:  auto; minimal  (gdb)   

i appreciate guys

 

you're passing char scanf. scanf expect receive ? char appropriate ?

here, i'll give strong hint, appropriate lines in man page :

quote

each successive pointer argument must correspond each suc-
cessive conversion specifier (but see * conversion below). con-
versions introduced % (percent sign) character.
