Performs a very weak form of "encryption" by adding 13 to each character of the string.
string encrypt(const char* input)
{
char* encrypted = new char[strlen(input) + 1];
for (unsigned int i = 0; i < strlen(input); i++) {
encrypted[i] = input[i] + 13;
}
encrypted[strlen(input)] = '\0';
string result(encrypted);
delete[] encrypted;
return result;
}
