 #define  MIN_PER_HOU 60 // There are... Every hour 60 minute 
 int  main (int argc,char *argv[]){
 	int hours, minutes, input;
	printf("CONVERT MINUTES  TO HOURS!\n");
	printf("PLEASE INPUT THE NUMBER OF MINNUTES(<=0 TO QUIT):“);
	scanf("%d",&input);
	while(input >0){
		hours=input/MIN_PRT_HOU:
		printf("CONVERT TO %d HOUT AND %dMINUTES\n",houts,minutes);
		printf("PLEASE CONTINUE INPUT UHE NUMBER OF MINUTES (<=0TO  QUIT):");
		scant("%d",&input);
	}
	printf("PROGRAM EXIT!\n");

The second question is

   /*huang
   */
   #include<stdio.h>
