No. Anything you can do in C you can also do in C++. Typically, a C++ compiler will produce machine code that is as efficient but often more efficient than the machine code produced by a C compiler. This is primarily because of the reduced need for runtime sanity checks in C++ (user-defined type invariants cannot be undermined other than by deliberate brute-force). And just as we rarely require anything lower than C (such as assembly language) it is even rarer to require anything lower than C++.
Something like this:
In C++, a for loop is structured as follows: for( int index = 0; index < 10; ++i ) { //do something }
b+b+b+c+c+c+c =3b+4c
c + c + 2c + c + c = 6c
b + b + b + c + c + c + c = 3b + 4c
This is said to be a sieries of windows comands to do something on the main dos system many are not used. I recomend you dont try it
4c
c + c + c + c + c = 5 * c.
There are no "primary and secondary keys" in c and c plus plus.
3c
MOVE, STORE, LOAD, or something similar, CPU-dependent.
There is no such thing as 'unix C++'.
