c언어 질문있습니다

# include<stdio.h>
 
int main(void)
{	//char nowHou =0, nowMin =0, nowSec =0;  StackOverFlow Error Why? 
	//short nowHou =0, nowMin =0, nowSec =0;  StackOverFlow Error
	int nowHou =0, nowMin =0, nowSec =0;
 
	scanf("%d %d %d",&nowHou,&nowMin,&nowSec); //현재시간입력 범위지정 할 수 없을까?
	printf("%d %d %d",nowHou,nowMin,nowSec); 
 
	return 0;
}
