统计字符的个数，记录出现最少的字符，然后再输出

#include <iostream>using namespace std;int main()
{char str[100];cin >> str;// 统计字符大小int count[256] = {0};char *p = str;while (*p != '\0'){count[*p]++;p++;}// 记录出现最少的字符 出现的次数int min = count[str[0]];p = str+1;while (*p != '\0'){if (min > count[*p])min = count[*p];p++;}// 输出p = str;while (*p != '\0'){if (min != count[*p])cout << *p;p++;}cout << endl;return 0;
}
