有以下程序

struct S{ int n; int a[20]; };

void f(int *a,int n)

{ int i;

for(i=0;i<n-1;i++) a[i]+=i;

}

main( )

{ int i; struct S s={10,{2,3,1,6,8,7,5,4,10,9}};

f(s.a,s.n);

for(i=0;i<s.n;i++) printf("%d",s.a[i]);

}

程序运行后的输出结果是

A)2,4,3,9,12,12,11,11,18,9,

B)3,4,2,7,9,8,6,5,11,10,

C)2,3,1,6,8,7,5,4,10,9,

D)1,2,3,6,8,7,5,4,10,9,
