Based on what we learned about C++ primitive data types, variables and constants, let's look at an example that could apply to a seasoned software engineer's life.

Assume we are organizing a series of learning sessions on C++, where sessionsConducted is an integer representing the number of sessions held till date. avgRating is a float representing the average participant rating for these sessions. To mark the start of the sessions, we've defined a character type initialLetter starting with 'A'. Also, isLearningCpp is a boolean indicating whether the user is currently learning C++ or not.

The C++ code snippet provided shows how to declare these variables, assign values, and print the variables using cout. After running this code, you'll see printed details about these defined variables on the console. This gives you a hands-on understanding of working with different data types and variables in C++.

xxxxxxxxxx

#include <iostream>

using namespace std;

​

int main() {

  // Declaring integer type variable

  int sessionsConducted = 50;

​

  // Declaring float type variable

  float avgRating = 4.7;

​

  // Declaring char type variable

  char initialLetter = 'A';

​

  // Declaring boolean type variable

  bool isLearningCpp = true;

​

  // Printing the variables

  cout << "Sessions conducted: " << sessionsConducted << endl;

  cout << "Average rating: " << avgRating << endl;

  cout << "Initial letter: " << initialLetter << endl;

  cout << "Learning C++: " << isLearningCpp << endl;

​

  return 0;
