C语言题目

输入一组字符串 判断字符出现次数，并且有序输出？

#include"stdio.h"

char data_code[]={"zzzzxxxxddddeeeeaaaarrrr"} ,data_temp[256]={'\0'};
int i,lock[128],lock_number=0,j;

void Bubble_Sorting(int data[], int len)
{
	int i,k,data_;
	for (i = 0; i < len; i++)
	{
		for (k = 0; k < len - i-1; k++)
		{
			if (data[k] > data[k + 1])
			{
				data_ = data[k + 1];
				data[k + 1] = data[k];
				data[k] = data_;
			}
		}
	}
}
int main()
{
	for(i=0;data_code[i];i++)
	{
		j=0;
		if(data_temp[data_code[i]] == '\0')  //data not in data_temp 
		{
			data_temp[data_code[i]]=1;
	    	lock[lock_number++]=data_code[i];  //new data asc 
		}
		else //if data in data_temp
		{
			data_temp[data_code[i]]++;
		}
	}	
	Bubble_Sorting(lock,lock_number-1);
	for(j=0;j<lock_number;j++)
	{
	    printf("%c:%d\n",lock[j],data_temp[lock[j]]);
	}
	for(j=0;j<lock_number;j++)
	{
	    printf("%c",lock[j]);
	}
	return 0;
