We have been discussing arrays in the past week.
Our assignment was to create a program that took the first and last name of the user and output it in reverse order.



 
   

   
    cout << "please enter your first name: " << endl;
    char str1[30];
    cin >> str1;
   
   
    cout << "please enter your last name: " << endl;
    char str2[20];
    cin >> str2;
   
   
    cout << "Your name before manipulation: " << str1 << " " << str2 << endl;
   
   
    cout << "your name after: " << str2;
    strcpy(str2, str1);
    cout << " " << str2 << endl;
   
   
comments:
I could have eliminated 2 separate lines for the cin input, and just did,
cin >> str1 >> str2
char str1[30];
char str2[25];

or something close to that.
I also feel it kind of redundant the way we have to reverse order.
Cout str2 and then copy the value of str1 into str2 and output it again.
A better way I think is we could just cout >> str2 >> str1
This eliminates extra code, along with if you have to use str2 again latter on the in the program you can use it as the "real" value of str2
