[程序填空题]下面程序从一个二进制文件中读入结构体数据,并把结构体数据显示在终端屏幕上。请填入适当内容。 #include
struct rec { int num; float total; }; int main() { FILE *f; if((f=fopen("bin.dat","rb"))==NULL); {printf("cannot open\n");exit(0);} reout(f); fclose(f); return 0; } void reout( ) { struct rec, r; fread(&r, ,1,f); while(!feof(f)) { printf("%df,%f\n", ); fread( ,1,f); } }
