A two-stroke, or two-cycle, engine is a type of internal combustion engine which completes a power cycle with two strokes (up and down movements) of the piston during only one crankshaft revolution. This is in contrast to a  four-stroke engine , which requires four strokes of the piston to complete a power cycle. two-stroke engine, in this case with an expansion chamber illustrates the effect of a reflected pressure wave on the fuel charge. This is essential for maximum charge pressure (volumetric efficiency) and fuel efficiency. It is used on most high-performance engine designs.
More than that, because the array is a reference type, the amount of memory that resides on the stack along with the containing struct for a particular array is always equivalent to the native int pointer size (which is 32 on 32 bit Windows and 64 on 64 bit windows).
In computer science, an associative array, map, symbol table, or dictionary is an abstract data type composed of a collection of (key, value) pairs, such that each possible key appears at most once in the collection. Operations associated with this data type allow: the addition of a pair to the collection.
