数据的简单加密和解密

#include<iostream>
using namespace std;
int main()
{
	//数组的简单加密(+5)
	char a[100] = { 0 };
	char b[100] = { 0 };
	cout << "请输入要加密的信息:" << endl;
	cin >> a;
	int i = 0;
	while (a[i] != '\0')
	{
		b[i] = a[i] + 5;
		i++;
	}
	b[i] = '\0';
	cout << "加密后的数据为:"<<endl << b << endl;

	//数组的简单加解密(-5)
	i = 0;
	while (b[i] != '\0')
	{
		a[i] = b[i] - 5;
		i++;
	}
	a[i] = '\0';
	cout << "解密后的数据为:" << endl << a << endl;
	return 0;
