How do you make a input and output basic statement in C plus plus?

Answer 1

The most basic input/output operations can be performed with std::cin for input and std::cout for output. For example:

#include<iostream>

int main (void) {

int n;

std::cout << "Enter a number: ";

std::cin >> n;

std::cout << "The value " << n << " was entered!\n";

}

Answer 2

std::cout << "Hello"; prints Hello cout stands for console output. << is the output operator. Everything in quotes is the text being printed out.

std::cin >> x; stores whatever the user inputs in the variable x. cin stands for console input, >> is the input operator.

You have to write std:: because cin and cout are members of the standard namespace libary. If you write using namespace std; right under your include files you dont have to write std::.

Answer 3

Functions, not statements: open/creat/close/read/write.
