Line 1: In [[computer programming]], a [[variable]] or object declared with the '''volatile''' [[keyword (computer programming)\|keyword]] may be modified externally from the declaring object. For example, a variable that might be concurrently modified by multiple [[thread (computer science)\|thread]]s ~~should~~may be declared volatile. Variables declared to be volatile will not be [[compiler optimization\|optimized]] by the [[compiler]] because the compiler must assume that their values can change at any time. Note that operations on a volatile variable are still not guaranteed to be [[atomic operation\|atomic]]. ==What can happen if volatile is not used?==
