question about "scanf"

[news]

Hi
I have problem:
My program reads 3 digits from keyboard using scanf("%d", &a)
then calculate it,everything is OK until I put "1,2,3,4,5,6,7,8,9,0"
but if I put "char " like "a,b,c,d etc" my program terminates
So,Is any method to verfity what kind of data is used(digits or chars)
if digits then OK if chars then show messege" use digits"
I'm beginer in C++

hi
the problem is that u r entering more integers than required
so first three integers are being used by scanf and the remaining are
implicitly given to the character input that is the reason u r not
getting the chance to input for the characters

ok bye
