    C++ question...awesome question....challenging too !!!

    How to write the c++ code for this sorta question....i couldnt get the logic even.....

    to print the factors of a number given by the user in a pyramid pattern...like if 4 is the number given by the user...its factors are 1,2,4...the we hv to print that in the format i hv provided in the attachment.....

    I hv attached a file to show how the output must look like....plez help !!!

    Attempt to the solution :
    To print stars in a pyramid format i could frame the code for printing 1 22 333..but couldnt for this question.....

    Code (Text):

    #include <iostream>
    using namespace std;

    int main() {

        // Loop through each row of the pyramid (1 - 9)
        for (int i = 1; i <= 9; i++) {

            // Create lead periods
            int totalperiods = 10 - i;
            for (int leadperiod = 1; leadperiod <= totalperiods; leadperiod++) {
                cout << ".";

            // Now for each row, print that many numbers with a space in between
            // Spaces are needed in between due to the monospaced formatting.
            // A space takes the same width as a number so to stagger you need placeholders.

            for (int j = 0; j < i; j++) {
                cout << " " << i;

            // End pyramid line
            cout << endl;

        return 0;
    and by the way..is this correct....???...and ple help for the code i hv given....

    Please do not use textspeak when posting here at Physics Forums. Do not use "hv" for have, "plz" for please, and so on.

    I don't understand what you're trying to do. The attached file shows a pyramid with numbers in it, but your code is just printing periods and spaces.
