利用fgets和fputs实现文件拷贝

#include <stdio.h>

int main()
{
FILE *fpSrc=NULL;
FILE *fpDst=NULL;
char str[11];
if ((fpSrc=fopen("src.txt","r"))==NULL)
{
printf("Can't open the file!\n");
exit(0);
}
if ((fpDst=fopen("dst.txt","w"))==NULL)
{
printf("Can't open the file!\n");
exit(0);
}
while(fgets(str,10,fpSrc)!=NULL)
{
puts(str);
fputs(str,fpDst);
}
if (fpSrc!=NULL)
{
fclose(fpSrc);
}
if (fpDst!=NULL)
{
fclose(fpDst);
}
getchar();
return 0;
}
