谁能够告诉我这题c怎么做得?

#include <stdio.h>
<br>
<br>main()
<br>
<br>{
<br>
<br>int k=0; char c=‘A’;
<br>
<br>do{
<br>
<br>switch(c++)
<br>
<br>{
<br>
<br>case ‘A’: k++; break;
<br>
<br>case ‘B’: k--;
<br>
<br>case ‘C’: k+=2; break;
<br>
<br>case ‘D’: k=k%2; continue;
<br>
<br>case ‘E’: k=k*10; break;
<br>
<br>default: k=k/3;
<br>
<br>}
<br>
<br>k++;
<br>
<br>}while(c&lt;‘G’);
<br>
<br>printf(“k=%dn”,k);
<br>
<br>}
<br>
<br>A）k=3 B）k=4 C）k=2 D）k=0
