Here are some examples: size_t a = sizeof(int); size_t b = sizeof(float); size_t c = sizeof(7); size_t d = sizeof(3.234); size_t e = sizeof a; The result of the sizeof operator is of a type called size_t, which is defined in the header file <stddef.h>. size_t ...

The only real difference is that in C++ we calloperator <<with two arguments (std::coutand the string). We could remove even that slight difference by using a closer C eqivalent:fprintf, which also has a first argument specifying the stream. ...
