Sort Seven Numbers in Descending

Write a C++ program that reads seven numbers and sorts them in descending order.

Visual Presentation:

Sample Solution:

C++ Code :

#include <iostream> // Including input-output stream header file
using namespace std; // Using the standard namespace

int main() {
    int num[7]; // Declaring an array 'num' of size 7 to store integers

    // Loop to read 7 integers from the input and store them in the array 'num'
    for (int i = 0; i != 7; ++i) {
        cin >> num[i]; // Reading integers from the input and storing them in 'num'
    }

    sort(num, num+7); // Sorting the elements in the 'num' array in ascending order

    // Outputting the elements of 'num' array in descending order (from largest to smallest)
    cout << " " << num[6]  << " " << num[5]  << " " << num[4]  << " " << num[3]  << " " << num[2] << " " << num[1] << " " << num[0];

    return 0; // Indicating successful completion of the program
}

Sample Output:

Sample Input 
2 5 8 9 7 3 4 
sample Output
 9 8 7 5 4 3 2
