有以下程序#include <stdio.h>#define N 4void fun(int a[][N], int b[]){ int i;for(i=0;

有以下程序#include <stdio.h>#define N 4void fun(int a[][N], int b[]) { int i; for(i=0; i<N; i++) b[i]=a[i][i];}main(){ int x[][N]={{1,2,3},{4},{5,6,7,8},{9,10}},y[N], i; fun(x,y); for (i=0; i<N; i++) printf("%d,", y[i]); printf("\n");}程序的运行结果是A．l,2,3,4, B．1,0,7,0, C．1,4,5,9, D．3,4,8,10,
