有如下程序:
#include＜iostream.h＞
void main( )
char ch[2] [5] ＝"6937","8254"，* p[2] ;
int i,j,s＝0;
for(i＝0;i＜2;i＋＋) p[i] ＝ch[i] ;
for(i＝0;i＜2;i＋＋)
for(j＝0;p[i] [j] ＞’\0’;j＋＝2)
s＝10 * s＋p[i] [j] －’0’;
cout ＜ ＜ s;
该程序的输出结果是

A．7
B．8
C．11
D．12

A．double x[5] ＝2.0,4.0,6.0,8.0,10.0;
B．int y[5] ＝0,1,3,5,7,9;
C．char c 1[ ] ＝'1','2','3','4','5';
D．char c 2 [C] ＝，'\x10','\xa','&
