Question

C语言怎打开一个有内容的文件啊?

#include <stdio.h>
#include <stdlib.h>
void main()
{
FILE *fp;
char *filename = "C:\\Program Files\\Microsoft Visual Studio\\REDIST.TXT";
fp = fopen(filename,"r");
if(fp == NULL)
{
printf("File open error\n");
exit(0);
}
}
我错在哪呢?就是不显示文件的内容,望高手指教

#include <stdio.h>
#include <stdlib.h>
void main()
{
FILE *fp;
char ch;
char *filename = "C:\\Program Files\\Microsoft Visual Studio\\REDIST.TXT";
fp = fopen(filename,"r");
if(fp == NULL)
{
printf("File open error\n");
exit(0);
}
ch=fgetc(fp);
while(!feof(fp))
{
putchar(ch);
ch=fgetc(fp);
}
fclose(fp);
}
