阅读以下程序,对程序功能的描述中正确的是 #icnlude int main() { FILE *in, *out; char ch, infile[10], outfile[10]; printf("Enter the infile name:"); scanf("%s", infile); printf("Enter the outfile name:"); scanf("%s", outfile); if ((in = fopen(infile, "r")) == NULL) { printf("cannot open infile."); exit(0); } if ((out = fopen(outfile, "w")) == NULL) { printf("cannot open outfile."); exit(0); } while (!feof(in)) { fputc(fgetc(in), out); } fclose(in); fclose(out); return 0; }

阅读以下程序,对程序功能的描述中正确的是 #icnlude int main() { FILE in, out; char ch, infile[10], outfile[10]; printf("Enter the infile name:"); scanf("%s", infile); printf("Enter the outfile name:"); scanf("%s", outfile); if ((in = fopen(infile, "r")) == NULL) { printf("cannot open infile."); exit(0); } if ((out = fopen(outfile, "w")) == NULL) { printf("cannot open outfile."); exit(0); } while (!feof(in)) { fputc(fgetc(in), out); } fclose(in); fclose(out); return 0; }

阅读以下程序,对程序功能的描述中正确的是
#icnlude
int main()
{
FILE *in, *out;
char ch, infile[10], outfile[10];
printf("Enter the infile name:");
scanf("%s", infile);
printf("Enter the outfile name:");
scanf("%s", outfile);
if ((in = fopen(infile, "r")) == NULL)
{
printf("cannot open infile.");
exit(0);
}
if ((out = fopen(outfile, "w")) == NULL)
{
printf("cannot open outfile.");
exit(0);
}
while (!feof(in))
{
fputc(fgetc(in), out);
}
fclose(in);
fclose(out);
return 0;
}
