【单选题】
某人编写了下面的程序: Private Sub Command1_Click( ) Dim a As Integer,b As Integer a=InputBox(′′请输入整数′′) b=InputBox(′′请输入整数′′) pro a pro b Call pro(a+b) End Sub Private Sub pro(n As Integer) While (n>0) Print n Mod 10; n=n\10 Wend Print End Sub 此程序功能是:输入两个正整数,反序输出这两个数的每一位数字,再反序输出这两个数之和的每一位数字。例如,若输入123 和234,则应该输出: 3 2 1 4 3 2 7 5 3 但调试时发现只输出了前2 行(即两个数的反序),而未输出第3 行(即两个数之和的反序),程序需要修改。下面的修改方案中正确的是( )。A.
把过程pro 的形式参数n As Integer 改为ByVal n As Integer
B.
把Call pro(a+b)改为pro a+b
C.
把n=n\10 改为n=n/10
D.
在pro b 语句之后增加语句c%=a+b,再把Call pro(a+b)改为pro c
