如何输出复数文件？

[jacksonsnake]

需要把buffer[32][i]里面32行数据的每一行数据分别写进32个不同的txt文件里，每行的长度不同，应该如何输出文件名？

FILE *fp=NULL;
char filename[256];

for(k=0; k<32; k++)
{
.................
.................

[ChamPagneZ]

是这种么?

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main(){
	char filename[256];
	char *add=".txt";
	FILE *fp=0;
	int i=0;
	char a[5][256]={
		{"Hello"},
		{","},
		{"World"},
		{"!"},
		{"!!"}
	};
	for (i=0;i<5;i++){
	char *temp=filename;
	temp=itoa(i+1,temp,10);
	temp=strcat(temp,add);
	if((fp=fopen(temp,"w"))!=0)
		fprintf(fp,"%s",a[i]);
	}
	return 0;

}

是比如说第一行写进一个新的文档文件“data 1.txt”，第二行写进“data 2.txt”，第i行写进“data i.txt”

[jacksonsnake]

这样行不？
=======================================================
int sequence[32][256]={
{1,2,3,4,5,6,7,8,9},
{2,3,4,5,6,7,8,9,1},
{3,4,5,6,7,8,9,1,2)
};
char Outfile[20]="data";
char temp[10];
char word[]=".txt";
for(i=0; i < 3; i++)
{/* output each sequence to one file */
itoa(i+1, temp, 10);/* integer to array */
Outfile = strcat(Outfile, temp);
Outfile = strcat(Outfile, word);
fp = fopen(Outfile, "w")
if(fp == NULL)
printf("\nFail to write file %s", Outfile);
else
fprintf(fp, %s, sequence[i]);
fclose(fp);
}

[jacksonsnake]

不行啊，调试卡在itoa的地方
itoa(i+1, temp, 10);/* integer to array */
Outfile = strcat(Outfile, temp);/* copy the file number to the end of the path */
Outfile = strcat(Outfile, word);/* set the file as txt file */

[Quote=引用 7 楼 jacksonsnake 的回复:]
itoa(i+1, temp, 10);/* integer to array */
[/Quote]
改成这样:

temp=itoa(i+1, temp, 10);

[jacksonsnake]

还是不行啊！

因为我自己测试过了才发给你.
你的Main函数太大了,你可以单步一下看下,至少,你函数执行成功的条件下都没有设置返回呢.
你的错误信息能贴出来看看么?

我贴的这个应该就是你要的这种吧.

1楼忘了fclose

里面错误太多了,还没缩进.
能说明问题就好了.哈哈

[jacksonsnake]

我就把
temp = itoa(i+1, temp, 10);/* integer to array */
Outfile = strcat(Outfile, temp);/* copy the file number to the end of the path */
Outfile = strcat(Outfile, word);/* set the file as txt file */
去掉就能成功debug～～～～～
