Development c++ need help

hi,
the below program is for a lab that i am doing in college, it suppose ask user to enter hour, minutes, is it am or pm, then adds 1 minute to it. hour and am/pm also advance as pass 59mins or 12 hours.

everything else seems to be working but i couldnt get the prompt for am or pm (highlight in red), if i use scanf("%2s",&ampm), the value in minute will become 0 somehow. so can anyone help me with it?

thx

Code:

#include <stdio.h>
#include <conio.h>
void add_minute(int *hour, int *minute, char *ampm);

main()
{
	clrscr();
	int hour,min,x;
	char ampm;
	printf("Please the hour:\n");
	scanf("%i",&hour);
	printf("Minute:\n");
	scanf("%i",&min);
	[COLOR=DarkRed]printf("am or pm:");
	scanf("%c",&ampm);[/COLOR]
	add_minute(&hour,&min,&ampm);
	printf("\nThe new time is:\n");
	printf("%ihour(s) %iminute(s) %cm",hour,min,ampm);
	getch();

}

void add_minute(int *hour, int *min, char *ampm)
{
	*min=*min+1;
	if(*min>59)
	{
		*min=0;
		*hour=*hour+1;
	}
	if(*hour>12)
	{
		*hour=1;
		if(*ampm=='a')
			*ampm='p';
		if(*ampm=='p')
			*ampm='a';
	}

}
	

 

I can't see why it would reset the minute variable, but have you tried using cin >> ampm; (#inlcude <iostream.h>) instead of scanf? thats how I generally get values from standard I/O.

It's because when you call scanf("%c", %ampm), it is reading in the new line/caridge return when you hit enter from when you entered in the minutes. So a simple way would just to add a getchar() before you read in the ampm.

 

ok, got it

thx all
