本文实例讲述了C语言字符串原地压缩的实现方法，对于学习字符串操作的算法设计有不错的借鉴价值。分享给大家供大家参考。具体方法如下：
字符串原地压缩示例: "eeeeeaaaff"压缩为"e5a3f2"
具体功能代码如下：
/*

#include <iostream>
#include <iterator>
#include <algorithm>
using namespace std;
char array[] = "eeeeeaaaff";
char array2[] = "geeeeeaaaffg";
const int size = sizeof array / sizeof *array;
const int size2 = sizeof array2 / sizeof *array2;
void compression(char *array, int size)
{
int i = 0, j = 0;
int count = 0;
while(j < size) {
count = 0;
array[i] = array[j];
while(array[j] == array[i]) {
count++;
j++;
}
if(count == 1) {
i++;
}
else {
array[++i] = '0' + count;
++i;
}
}
array[i] = 0;
}
void main()
{
compression(array, size);
cout << array << endl;
compression(array2, size2);
cout << array2 << endl;
}
相信本文所述对大家C程序算法设计的学习有一定的借鉴价值。
