| |
| − | The better way to validate any attribute is to use functions .
| |
| − |
| |
| − | ValidYear = getYear(Year); // Bool function
| |
| − |
| |
| − |
| |
| − | Check what do functions cin.clear()and others mean .
| |
| − |
| |
| − |
| |
| − | I like the way the teacher sends the output to the function
| |
| − |
| |
| − | sendMsg("The number is", double number); // Something like that
| |
| − |
| |
| − |
| |
| − | bool validCCV(int ccv){
| |
| − | return ccv >= 100 && ccv <= 999;
| |
| − | } // Better example of the function above .
| |
| − |
| |
| − |
| |
| − | HomeWork - I have to understand how the program the teacher used works. I can find that program by the date in SVN. Then, I have to finish the assignment 1 (I did not send it yet, some errors appear).
