factore of 20 in c+

To find the factors of 20 in C++, you can use the following code:

#include <iostream>

int main() {
    int number = 20;

    std::cout << "The factors of " << number << " are: ";

    for (int i = 1; i <= number; i++) {
        if (number % i == 0) {
            std::cout << i << " ";
        }
    }

    std::cout << std::endl;

    return 0;
}

Explanation of each step:

#include <iostream>: This is a preprocessor directive that includes the iostream library, which is needed for input and output operations in C++.
int main(): This is the main function where the program execution starts.
int number = 20;: Declares and initializes a variable number with the value 20. This is the number for which we want to find the factors.
std::cout << "The factors of " << number << " are: ";: Outputs a message to the console indicating that the program will display the factors of the given number.
for (int i = 1; i <= number; i++) {: A for loop that iterates from 1 to the given number.
if (number % i == 0) {: Checks if the current value of i is a factor of the given number using the modulo operator (%).
std::cout << i << " ";: If the current value of i is a factor, it is outputted to the console.
std::cout << std::endl;: Outputs a new line to the console.
return 0;: The main function ends and returns 0, indicating successful program execution.

This code will display the factors of 20 as: "The factors of 20 are: 1 2 4 5 10 20".
