蓝桥杯算法提高VIP-文本加密 （C++和python代码）

解题思路:

注意事项:

参考代码:

//C++

#include<iostream>

#include<string>

using namespace std;

string EncryptChar(string str)

{

int len;

len = str.length();

for (int i = 0; i < len; i++)

{

if ((str[i] >= 'A' && str[i] < 'Z') || (str[i] >= 'a'&&str[i] < 'z'))

{

str[i] += 1;

}

else if (str[i] == 'Z')

str[i] = 'a';

else if (str[i] == 'z')

str[i] = 'A';

}

return str;

}

int main()

{

string str;

while(cin >> str)

cout << EncryptChar(str) << endl;

return 0;

}

#python

def EncryptChar(str):

    length = len(str)

    num = []

    for i in range(0,length):

        num.append(ord(str[i]))

    for i in range(0,length):

        if ((num[i] >= 65 and num[i] < 90) or (num[i] >= 97 and num[i] < 122)):

            num[i] += 1

        elif num[i] == 90:

            num[i] = 97

        elif num[i] == 122:

            num[i] = 65

    for i in range(0,length):

        num[i] = chr(num[i])

    str = ''.join(num)

    return str

while True:

    str = input()

    str1 = EncryptChar(str)

    print(str1)
