In this lab, you declare and initialize variables in a C++ program. The program, which is saved in a file named NewAge.cpp, calculates your age in the year 2050. Instructions Declare an integer variable named myNewAge. Declare and initialize an integer variable named myCurrentAge. Initialize this variable with your current age. Declare and initialize an integer variable named currentYear. Initialize this variable with the value of the current year. Use four digits for the year. Execute the program by clicking the Run button at the bottom of the screen. Sample program execution: My Current Age is 29. I will be 65 in 2050.
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.
