This predefined extractor is mentioned here because it can cause problems. Use it like this:
char x[50]; cin >> x; |
This extractor skips leading whitespace and extracts characters and copies them to x until it reaches another whitespace character. It then completes the string with a terminating null (0) character. Be careful, because input can overflow the given array.
You must also be sure the pointer points to allocated storage. For example, here is a common error:
char * p; // not initialized cin >> p; |
There is no telling where the input data will be stored, and it may cause your program to abort.
