C语言完美演绎9-29
/* 范例：9-29 */
#include <stdio.h>
#include <stdlib.h>
void main(int argc,char *argv[])
{
FILE *fp1;
int ch;
if(argc!=2)
{
printf("Syntax Error!\n\tp9-29 filename");
exit(1);
}
if((fp1=fopen(argv[1],"r"))==NULL)
{
printf("Read file %s Error!\n",argv[1]);
exit(1);
}
while(!feof(fp1))
{
ch = getc(fp1);
if(ch!=-1)
putchar(ch);
}
fclose(fp1);
}
