24）阅读下列程序,则执行后的结果为 #include "stdio.h" main() { int c[][4]={1,2,3,4,5,6,7,34,213,56,62,3,23,12,34,56}; printf("%x,%x\n",c[2][2],*(*(c+1)+1));} (A)3e,6 (B)62,5 (C)56,5 (D)3E,6

30）有以下程序 #include main() {FILE *fp;int k,n,a[6]={1,2,3,4,5,6}; fp=fopen("d2.dat","w"); fprintf(fp,"%d%d%d\n",a[0],a[1],a[2]); fprintf(fp,"%d%d%d\n",a[3],a[4],a[5]); fclose(fp); fp=fopen("d2.dat","r"); fscanf(fp,"%d%d",&k,&n);printf("%d%d\n",k,n); fclose(fp); } 程序运行后的输出结果是 (A)1 2 (B)1 4 (C)123 4 (D)123 456
