loop execution decending order in c

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

#include <iostream>
using namespace std;

int main() {
   int i;

   for (i = 10; i >= 1; i--) {
      cout << i << " ";
   }

   return 0;
}

Explanation for each step:

1. The #include <iostream> statement includes the necessary input/output library for the program.
2. The using namespace std; statement allows us to use the cout object from the std namespace without explicitly specifying it.
3. The int main() function is the entry point of the program.
4. The variable i is declared as an integer.
5. The for loop is used to execute a block of code repeatedly. Here, the loop variable i is initialized to 10, and the loop will continue as long as i is greater than or equal to 1. After each iteration, the value of i is decremented by 1 using the i-- statement.
6. Inside the loop, cout << i << " "; is used to print the value of i followed by a space.
7. After the loop completes, the return 0; statement indicates that the program has executed successfully.

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