Why scanf asks for one more entry/value?

[minduser]

Here`s a simple program to convert time into seconds. For ex. 23:00:59-->82859.
The problem is that the scanf always ask for a 4th value, which is not used in the conversion. Why? I`m using gcc.

int convert(int hora, int minuto, int segundo){
int i;

i = hora*3600 + minuto*60 + segundo;
return i;
}

int main(void){
int h,m,s;
scanf("%d\n", &h);
scanf("%d\n", &m);
scanf("%d\n", &s);

printf("%d\n",c onvert(h,m,s));
return 0;

}

Take out those "\n" characters from the scanf() calls.

What do you mean "scanf always asks for a 4th value"?
scanf doesn't display a prompt, so it isn't clear to me that it can ask for anything.
