loop execution descending order in c++

Here is an example of a loop in C++ that executes in descending order:

#include <iostream>

int main() {
    int n = 10;

    for (int i = n; i >= 1; i--) {
        std::cout << i << " ";
    }

    return 0;
}

Explanation:

1. The #include <iostream> statement includes the necessary header file for input and output operations in C++.

2. The int main() function is the entry point of the program.

3. The variable n is initialized with the value 10.

4. The for loop is used to execute a set of statements repeatedly. It consists of three parts: initialization, condition, and increment/decrement.

5. In the initialization part, the variable i is initialized with the value of n. This sets the starting point of the loop.

6. In the condition part, the loop will continue executing as long as the condition i >= 1 is true. This ensures that the loop will iterate as long as i is greater than or equal to 1.

7. In the increment/decrement part, i-- is used to decrement the value of i by 1 in each iteration. This ensures that the loop will move towards the desired descending order.

8. Inside the loop, the statement std::cout << i << " "; is used to print the current value of i followed by a space. This will output the numbers in descending order with spaces separating them.

9. After the loop, the return 0; statement indicates the successful termination of the program.

This program will output the numbers from 10 to 1 in descending order.
