    encrypt

    I'm trying to encrypt this char array using pointer subscript notation and I need help with the algorithm. I don't understand how the ENCRYPTION_KEY affects the encryption and how to utilize it.
    Code:
    #include<iostream>
    #include<conio.h>
    #include<string>
    #include<cstring>
    
    using namespace std;
    
    
    //encrypt(char *ptr);
    const int ENCRYPTION_KEY = 1;
    void main()
    {
    
    char temp1[26];
    char temp2[26];
    char password[11];
    char *ptr;
    
    cout<<"Please enter a password no more than 25 characters in length: ";
    cin>>temp1;
    cout<<temp1;
    cout<<"Re-enter your password: "<<endl;
    cin>>temp2;
    cout<<temp2<<endl;
    cout<<strcmp(temp1, temp2)<<endl;
         while (strcmp(temp1, temp2) !=0){
                cout<<"Invalid Password"<<endl;
                cout<<"Re-enter your password: "<<endl;
    	        cin>>temp2;
    			}
    
    	 strncpy (password, temp1, 11);
    	 password[10]='\0';
                     cout<<password<<endl;
                     ptr=password;
    
     //encrypt(ptr);
     getch();
     }
    
    //void encrypt(char *ptr)
          //{
           //for (i =0; i<11; i++)
           //ptr[i] 
    	//}

    I don't know what you meant by the encryption key?
    But I think that it should be the base you will do the encryption based on.
