c++ watch a variable

Watch a Variable in C++

#include <iostream>
using namespace std;

int main() {
    int x = 5;
    cout << "Initial value of x: " << x << endl;

    x = 10;
    cout << "New value of x: " << x << endl;

    return 0;
}

In this example, we declare a variable x and initialize it with the value 5. We then output the initial value of x using cout. Next, we update the value of x to 10 and output the new value using cout. Finally, the program returns 0, indicating successful execution.
