Common output methods of stringWithFormat:
NSString*height
Height= [NSString stringWithFormat:@ "Yourheightis%dfeet,%dinches.", 5J 11]
NSLog (@ "% @", height)

How to output multiple characters (take two characters as an example):
NSString*str
NSString * str1= @ "123"
NSString*str2=@ "465"
Str= [NSStringstringWithFormat:@ "% @,% @", str1,str2]
NSLog (@ "% @", str)
