请问 怎么写入文件？

[liu_qi2006]

做一个函数 fun(CString Path);

需求 用户 一旦把PATH 传进来
则 在一个a.txt写下

aPath = Path 的完整路径 Path随用户的地址可变

请大家帮帮我

[折腾_苏州]

#include <fstream.h>
fun(CString Path)
{
fstream filein;
filein.open("a.txt",ios::out);
filein<<"aPath ="<<Path<<endl;
filein.close();//关闭文件
}

如何写文件：
常用的几种类型都有了！
#include <stdio.h>
#include <process.h>

FILE *stream;

void main( void )
{
int i = 10;
double fp = 1.5;
char s[] = "c:\windows\system.ini";
char c = '\n';

stream = fopen( "fprintf.out", "w" );
fprintf( stream, "%s%c", s, c );
fprintf( stream, "%d\n", i );
fprintf( stream, "%f\n", fp );
fclose( stream );
system( "type fprintf.out" );
}

fun(CString Path)
{
CFile file;
file.Open(Path+"\\a.txt",CFile::modeReadWrite | CFile::modeCreate);
file.Write(LPCTSTR("aPath="+Path),Path.GetLength()+5);
file.Close();
}
