。49)閱讀以下程序及對程序功能的描述,其中正確的描述是
#include <stdio.h>
main()
{
FILE *in,*out;
char ch,infile[10],outfile[10];
printf("Enter the infile name:\n");
scanf("%s",infile);
printf("Enter the outfile name:\n");
scanf("%s",outfile);
if((in=fopen(infile,"r"))==NULL)
{
printf("cannot open infile\n");
exit(0);
}
if((out=fopen(outfile,"w"))==NULL)
{
printf("cannot open outfile\n");
exit(0);
}
while(! feof(in))fputc(fgetc(in),out);
fclose(in);
fclose(out);
}
