An exercise about drawing a rectangle class using the printf function -

so problem next :

"write method rectangle class called draw draws rectangle using dashes , vertical bar characters. next code sequence

rectangle *myrect = [[rectangle alloc]init]; [myrect setwidth : 10 andheight : 3]; [myrect draw];

would produce next output : "

(i cant show image rectangle made out of "-" dashes , "|" bar characters. dashes width , bar characters height.)

i've started doing method :

{ int n; ( n = 1 ; n <= self.width ; ++n) printf ("-"); ( n = 1 ; n <= self.height ; ++n){ printf ("\n|"); } printf("\n"); ( n = 1 ; n <= self.width ; ++n){ printf ("-"); }

but seems not going work , cant display outer (|) lines . help me on one?

i believe working in objective-c, here simple set of code tested in c should translate on easily:

void printrectangle(int width, int height) { int n; int z; printf(" "); (n = 1 ; n <= width ; n++) printf ("-"); printf("\n"); ( n = 1 ; n <= height ; n++) { printf ("|"); for(z = 1; z <= width; z++) printf(" "); printf("|\n"); } printf(" "); ( n = 1 ; n <= width ; ++n) printf ("-"); printf("\n"); }

output width = 10, height = 5
