 程序代码：#include <iostream> 似乎只能用这个方法了，何不直接用char[]？这样似乎还更有效。#include <string> #include <cstring> #include <cstdlib> using namespace std; int cmp(const void* cp1, const void* cp2) { return *(char*)cp1 - *(char*)cp2; } int main() { string str; char* temp; int n; cin >> n; while (n--) { cin >> str; temp = new char[str.size() + 1]; strcpy(temp, str.c_str()); qsort(temp, str.size(), sizeof (char), cmp); str = temp; cout << str << endl; delete temp; } } |
#include <iostream>
#include <string>
#include <cstdlib>
using namespace std;
int maxcmp(const void *a,const void *b)
{
printf("OK");
return *(char *)a-*(char *)b;
}
int main()
{
string a;
int n,i,len,sum;
cin>>n;
while (n--)
{
sum=0;
cin>>a;
len=a.size();
qsort(&a,len,sizeof(a[0]),maxcmp);
cout<<a;
}
return 0;
}
