helo there..
i have a function called choice below and i want to use it to produce a void function do_set_time.i am not sure how to name the parameters in my function call. please help...
scroll function is as follows:it scrolls message on the screen
this is the choice function for one to be able to pick an item from a scrolling menu
this is what i tried to come up with
dont hesitate to ask if you need more clarity..

this is what i tried to come up with
Code C - [expand] 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 extern void scroll(const char *mess, unsigned char ntimes); extern void clrscr(void); extern char choice(const char *const *menu); void do_set_time (int i, const char *const menu2[]){ const char *const menu2[]={ "CLK TIME", /*parameter==0*/ "ON TIME", /*parameter==1*/ "OFF TIME", /*parameter==2*/ 0}; if(i=0){printf("set system clock"); } else if(i=1){printf("set geyser ON time"); } else if(i=2){printf("set geyser OFF time"); } }//the three parameters will have same code, and what is being pointed to will //be executed in the main code.
