Declaring and Initializing C++ Variables Summary 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 1. Declare an integer variable named myNewAge. 2. Declare and initialize an integer variable named myCurrentAge. Initialize this variable with your current age. 3. Declare and initialize an integer variable named currentYear. Initialize this variable with the value of the current year. Use four digits for the year. 4. 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. Grading When you have completed your program, click the Submit button to record your score.

Question
// This program calculates your age in the year 2050.
// Input: None
// Output: Your current age followed by your age in 2050
#include <iostream>
using namespace std;
int main()
{ myNewAge;
myCurrentAge;
// Declare and initialize your variables here
myNewAge = myCurrentAge + (2050 - currentYear);
cout << "My Current Age is " << myCurrentAge << endl;
cout << "I will be" << myNewAge << " in 2050." << endl;
return 0;
}
Expert Solution
Step 1: Understanding the problem
Declaring data type in C++
When the variables in the example above are declared, they have an undetermined or garbage value until they are assigned a value for the first time. But it is possible for a variable to have a specific value from the moment it is declared. This is called the initialization of the variable.
In C++, there are same ways to initialize variables as in C Language.
Syntax:
type identifier = initial_value;
Example:
int a = 10; //integer variable declaration & initialization.
