下面程序运行后的结果是（ ）。#includeint main(){ FILE *fp; int i,m=9,n=9; fp=fopen("d:\\test.txt","w"); for(i=0;i<5;i++)fprintf(fp,"%d",i); fclose(fp); fp=fopen("d:\\test.txt","r"); fscanf(fp,"%d%d",&m,&n); fclose(fp); printf("m=%d,n=%d\n",m,n); return 0;}
有以下程序#includeint main(){ FILE *fp; fp=fopen("filea.txt","w"); fprintf(fp,"abc"); fclose(fp); return 0;}若文本文件filea.txt中原有内容为“hello”，则运行以上程序后，文件filea.txt中的内容为（ ）。
