做了一下华为机试，代码可能还有些问题，先传上去，第三题会有些问题。第一题
#include<iostream>
#include<vector>
#include<string>
#include<algorithm>
using namespace std;
int main()
{
int p1, p2, p3;
cin >> p1>>p2>>p3;
string str;
cin >> str;
vector<char>res;
for (int i = 0; i < str.size(); i++)
{
if (str[i] != ‘-‘)
{
res.push_back(str[i]);
}
else
{
if (0<i<str.size()-1&&abs(str[i + 1] - str[i - 1]) > 25)
{
res.push_back(str[i]);
}
if (0 < i < str.size() - 1 && abs(str[i + 1] - str[i - 1] <= 0))
{
res.push_back(str[i]);
}
int flag = 0;
for (int j = str[i - 1] + 1; j < str[i + 1]; j++)
{
char addNums;
switch (p1)
{
case(1) :
addNums = j;
break;
case(2) :
addNums = toupper(j);
break;
case(3) :
addNums = ‘*‘;
break;
}
for (int k = 0; k < p2; k++)
{
res.push_back(addNums);
flag++;
}
}
if (p3 == 2)
{
int m;
m = res.size() - flag;
reverse(res.begin() + m , res.begin() + m+flag);
}
}
}
for (int i = 0; i < res.size(); i++)
{
cout << res[i];
}
cout << endl;
system("pause");
return 0;
}
第二题
#include<iostream>

else
return false;
}
}

}
}
}

}

{

}
第三题
#include<iostream>
#include<string>
#include<sstream>
#include<vector>
using namespace std;
struct PeopleIntroction
{

};
vector<string> peopleTemp(string &p)
{

}
return temp;
}

{

}
if (res.size() == 2)
{

if (res[0] == temp[0] && res[1] == temp[1])
{
cout << people[i].name << "\t" << people[i].phone;
}
temp.clear();
//按照首字母组合
for (int i = 0; i < nums; i++)
{
vector<string> temp;
temp = peopleTemp(people[i].name);
if (res[0][0] == temp[0][0] && res[1][0] == temp[1][0])
