b + b + b + c + c + c + c = 3b + 4c
c + c + c + c + c = 5 * c.
It is impossible to give any decimal/numeric value if we are not given the values of at least one variable, so the answer is B + B + B + C + C + C.
the answer is a
That is STANDARD input and STANDARD output. By default, standard input is the keyboard, and standard output is the screen. Standard I/O is set by the operating system, though it may be redirected by script invocation or system commands within the C/C++ program itself. You could, for instance, set standard output to a printer or a file in lieu of a screen. You should also Google Standard Error.
input is the << operator and output is the >> operator
No. The C++ standard library provides the global std::cout object which represents the console output stream. While it can use the computer's monitor (or rather, a command window) to present its output to the user, the user is free to redirect output to any device they wish, be it a printer, a file, or another program, even the nul device (a non-existent device that simply "eats" output). The default output device is implementation-defined but, in most cases, will default to the command window
You are probably referring to the global std::cout object, however std::cout does not put information on a screen, it puts information into the standard console output device which can be redirected to any output device the user chooses (the screen, a file, a line-printer, the nul device, etc).
A Monitor is an output device, but a CPU is not
example output of c++ calculator
There is no such thing as a null printer in C++. You are perhaps thinking of the null device to which output can be redirected from the command line (effectively hiding the output of a program). However this has nothing whatsoever to do with C++, it is entirely dependant upon the operating system.
For basic input and output in C++: #include
C. Microphone
stdio.h files are used in c ,because "stdio" stands for standard Input and Output files .these headers is connect i/o device to the compiler
Pipe the output to the MORE command.
There is no such header in C++. You must consult the documentation provided with the file. It is most likely related to console input/output, perhaps providing enhancements to the standard I/O stream implementation.
