C language programming> Eleventh week③ Assume that the input string only contains letters and "#" signs. Please write the function fun. Its function is to move all the leading "#" signs in the string to the end of the string.

Example: Assume that the input string only contains letters and "#" signs. Please write the function fun. Its function is to move all the leading "#" signs in the string to the end of the string.

例如，若字符串中的内容为 “###a#b#c#d###”,
移动后，字符串中的内容应当是 “a#b#c#d######”。
在编写函数时，不得使用C语言提供的字符串函数。
请勿改动主函数main与其它函数中的任何内容，仅在函数fun的花括号中填入所编写的若干语句。

代码如下：

#include<stdio.h>
#include<conio.h>
void fun(char*s)
{
    
    
	int i=0,n=0;
	char*p;
	p=s;
	while(*p=='#')
	{
    
    
		n++;
		p++;
	}
	while(*p)
	{
    
    
		s[i]=*p;
		i++;
		p++;
	}
	while(n!=0)
	{
    
    
		s[i]='#';
		i++;
		n--;
	}
	s[i]='\0';
}
main()
{
    
    
	char str[81],*p;
	FILE*out;
	char test[2][80]={
    
    "###A###B#CD######","###a#b#c#d###"};
	int i;
	printf("Enter a string:");
	gets(str);
	fun(str);
	printf("The string after moveing:");
	puts(str);
	out=fopen("outfile.dat","w");
	for(i=0;i<4;i++)
	{
    
    
		fun(test[i]);
		fprintf(out,"%s\n",test[i]);
	}
	fclose(out);
}

The output running window is as follows:
