In order to be able to use the cout , cin , and endl commands what line of C++ code must be included
Addition of Two Numbers
Adding two numbers in programming is essentially the same as adding two numbers in general arithmetic. A significant difference is that in programming, you need to pay attention to the data type of the variable that will hold the sum of two numbers.
C++
C++ is a general-purpose hybrid language, which supports both OOPs and procedural language designed and developed by Bjarne Stroustrup. It began in 1979 as “C with Classes” at Bell Labs and first appeared in the year 1985 as C++. It is the superset of C programming language, because it uses most of the C code syntax. Due to its hybrid functionality, it used to develop embedded systems, operating systems, web browser, GUI and video games.
C++
In order to be able to use the cout , cin , and endl commands what line of C++ code must be included in the
cin, cout and endl in C++
cin statement
The keyword cin refers to as "console input" that enables the user to input (or read) values from the keyboard in the C++ program. It is known to be a class istream object. Cin must be used along with the extraction operator (>>) to take input.
cout statement
cout is an output statement that displays (or prints) program output on the screen known as a console. It is known to be a class ostream object. It must be used with the insertion operator (<<) to get output on the screen.
endl statement
This statement inserts a new line whenever endl encounters in the C++ program. It is also an ostream class object so It must be used along with cout.
