You can always make a prank program
| Code: | | system("shutdown -s -t 0") // 0 means the seconds before your computer shutdown, r is restart and using -f should force your computer to shutdown |
or maybe its without ""

Do you think I didn't know that? :P Isn't it pretty oblivious? You should know what "sh" is..

It synchronizes the input buffer. For example:
You want to enter a certain amount of characters, lets say for this, you only want to allow an input of 1 character.
So your code (without any checks) is:
| Code: | char szFirstLetter;
cout << "Please enter a letter: ";
szFirstLetter = cin.get(); |
Now lets say we ran this, and instead of entering 1 letter or number or symbol, I entered a word, like my name, Wiccaan.
So our code would put W into szFirstLetter correctly, but would be overflowed with the rest of the word 'iccaan'. Now, if you attempt to cin again after that above code such as:
| Code: | char szSecondLetter;
cout << endl << "Please enter another letter: ";
szSecondLetter = cin.get(); |
Instead of obtaining the new input, it will automatically obtain the input buffers 'overflowed' information. In this case, szSecondLetter would become 'i' and the input buffer will still contain 'ccaan'.
So you would use cin.sync() to prevent the overflowing from occuring.
Proper example (without checks and shit):
| Code: | char szFirstLetter;
cout << "Please enter a letter: ";
szFirstLetter = cin.get();
cin.sync();
char szSecondLetter;
cout << endl << "Please enter another letter: ";
szSecondLetter = cin.get();
cin.sync();
cout << endl << "First letter was: " << szFirstLetter << endl;
cout << endl << "Second letter was: " << szSecondLetter << endl; |
