Baekjun, question 2588

Baekjun, I tried to solve question 2588 in a clueless way, but A and B came up with strange numbers I thought if I put 472, 385, I would get a multiplier, but I got a - or a 10 million digit number, so what's the reason? Is there anything wrong?

The problem is that if you are given three digits, such as 472,385, you will print 472X5472X8472X3472X385 over four lines! //

#include <stdio.h>
int main()
{


 int a,b,c,d,e,f,A,B;

A = 100*a+10*b+c;
B = 100*d+10*e+f;
scanf("%d,%d,%d",&a,&b,&c);
scanf("%d,%d,%d",&d,&e,&f);
printf("\n%d,%d,%d\n",A,B,A*B);
printf("%d\n%d\n%d\n%d",A*f+A*e,A*d,A*B);
return 0;
}...
