为什么在B文件中是乱码
main()
{FILE *p1,*p2;
int i=5,j;
int a[10],b[10];
if((p1=fopen("d:\\aa","w"))==NULL)
printf("the file can't open");
if((p2=fopen("d:\\bb","w"))==NULL)
printf("the file can't open");
for(i=0;i<10;i++)
{scanf("%c",&a[i]);
fputc(a[i],p1);}
rewind(p1);
for(i=0;i<10;i++)
{fputc(fgetc(p1),p2);
}
fclose(p1);
fclose(p2);

fputc 只对字符型起作用。不对整形。。。。。。

我把int a[10],b[10];变成了char a[10],b[10];还是不行呀

/*请你试试这个*/
#include<stdio.h> /*文件处理时决不能省*/
main()
{ FILE *p1,*p2;
int i=5;
int a[10];
if((p1=fopen("d:\\aa","w+"))==NULL)/*添+号*/
printf("the file can't open");
if((p2=fopen("d:\\bb","w"))==NULL)
printf("the file can't open");
for(i=0;i<10;i++)
{ scanf("%c",&a[i]);
fputc(a[i],p1);
}
rewind(p1);
for(i=0;i<10;i++)
{
fputc(fgetc(p1),p2);
}
fclose(p1);
fclose(p2);
}

大概问题如一二楼所讲
[CODE]
#include "stdio.h"

int main()
{
FILE *p1,*p2;
int i,j;
char a[10]; /*要处理数字的话要用fwrite()*/

if((p1=fopen("d:\\aa.txt","wt+"))==NULL)
printf("the file can't open\n");
if((p2=fopen("d:\\bb.txt","w"))==NULL)
printf("the file can't open\n");
for(i=0;i<10;i++)
{
scanf("%c",&a[i]);
fputc(a[i],p1); /*只针对字符*/
}
rewind(p1);
for(i=0;i<10;i++)
fputc(fgetc(p1),p2);
fclose(p1);
fclose(p2);

return 0;
}
[/CODE]

谢谢了哈
