C int mapping string

Encoding scheme defined by the following mapping: 

1->'A',
2->'B',
3->'C',
...,
9->'I',
0->'J'.

Input A three-digit integer N

Output The encoding result



int main(void) {

char dict[10] = {'A', 'B', 'C', 'D', 'E', 'F', 'G', 'I', 'J'};

int i;
while(EOF != scanf("%d", &i)) {

if (100 <= i && i <= 999) {

char data[3];
data[0] = dict[i/100-1];
i = i%100;
data[1] = dict[i/10-1];
i = i%10;
data[2] = dict[i-1];

printf("%s\n", data);
}
}
return 0;
