Data types and their sizes in c++
WebNov 19, 2015 · First, while the actual sizes of types in C++ is implemenation dependent (and there are implementations where char has 9 bits), on most platforms which support both languages, float and double have exactly the same size in both C++ and Java. WebAs char's size is always the minimum supported data type, no other data types (except bit-fields) can be smaller. The minimum size for char is 8 bits, the minimum size for short …
