open file
我想打开d:\try\wzw.txt(txt里是一个字符串I love flowers)把这个字符串读出来显示到屏幕上;这是dos下的
main()
{
FILE *fp;
if((fp=fopen("d:\\try\wzw.txt","r"))==NULL)
{
printf("文件不存在\n");exut(0);
};
while(!feof(fp));
putchar(fgetc(fp));
fclose(fp);
printf("\n");
}
VC2008这样改过不了,不知道为什么.#include <iostream>
int main()
{
FILE *fp;
if((fp=fopen("d:\\try\wzw.txt","r"))==NULL)
{
printf("文件不存在\n");exut(0);
};
while(!feof(fp));
putchar(fgetc(fp));
fclose(fp);
printf("\n");
return 0;
}

int main()
{
FILE *fp;
char * _MyFileName;
_MyFileName ="d:\\新建 文本文档.txt";
fp = fopen(_MyFileName,"r");
if(fp==NULL)
{
printf("文件不存在\n");
}
else
{
while(!feof(fp))
{
putchar(fgetc(fp));
//printf("\n");
}
fclose(fp);
}
system("pause"); //暂停控制台，防止一闪而过
return 0;
}参考下吧…… 谢谢 老大.我就去开vc2008.
