请教各位高手怎样将一个整型数组保存到一个txt文档中？

好像有一些对文件读写的函数可以用的吧~

飘过，就是文件操作嘛，Google！

你可以参考文件操作

[beginsoft_nj]

fopen(filename,"wb+");
fwrite(buf,1,size,pf);

[xx说就叫这个名字]

方法不少：
int fprintf(FILE *stream, const char *format, ...);
上面这函数可以！
size_t fwrite(const void *ptr, size_t size, size_t nmemb,FILE *stream);
这个函数也可以做到！

// crt_fprintf.c
/* This program uses fprintf to format various

*/

#include <stdio.h>
#include <process.h>

FILE *stream;

int main( void )
{
int i = 10;
double fp = 1.5;
char s[] = "this is a string";
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" );
}

正解。不过把FILE *变量命名为stream不如f或pF好。
