#include <iostream>

// Query the user for one positive integer 'm'
// and draw a right-aligned triangle of asterisks
// with 'm' rows.
//
// The first row contains one asterisk, the second
// row contains two asterisks, and so on, with the
// final row containing 'm' asterisks. Add spaces
// before the asterisks so that the right edge of
// the triangle is aligned.
//
// For example, if m = 5, the output should be
//
//     ^     *
//     |    **
//     5   ***
//     |  ****
//     v *****
//
// If the user enters a value for 'm' that is not
// positive, simply return 0.

// Function declarations
int main();

// Function definitions
int main() {
    return 0;
}



























// Hint:
//
// Like the previous exercise, we must print 'm'
// rows, so the outer loop will look like:
//
//     for ( int row{ 1 }; row <= m; ++row ) {
//
//         // Print the appropriate number of spaces.
//
//         // Print the appropriate number of asterisks.
//
//         std::cout << std::endl;
//     }
//
// This time, however, each row requires two inner
// loops. The first prints the spaces before the
// asterisks, and the second prints the asterisks.
//
// How many spaces and asterisks should be printed
// on each row?




























// The value of 'row' controls both the number of
// spaces and the number of asterisks.
//
// For example, if m = 5:
//
//     row       spaces       asterisks
//      1         5 - 1          1
//      2         5 - 2          2
//      3         5 - 3          3
//      4         5 - 4          4
//      5         5 - 5          5
//
// More generally, on each row:
//
//     number of spaces    = m - row
//     number of asterisks = row
//
// Therefore, inside the outer loop, use one loop
// to print 'm - row' spaces followed by another
// loop to print 'row' asterisks.
//
// The two inner loops may use the same loop-variable
// name because the variable declared in each for
// loop exists only within that loop.


































// Here is one solution:
/*
int main() {
    int m{};
    std::cout << "Enter a positive integer 'm': ";
    std::cin  >> m;

    if ( m <= 0 ) {
        return 0;
    }

    for ( int row{ 1 }; row <= m; ++row ) {

        // Print the spaces preceding the asterisks.
        for ( int column{ 1 }; column <= m - row; ++column ) {
            std::cout << " ";
        }

        // Print the asterisks.
        for ( int column{ 1 }; column <= row; ++column ) {
            std::cout << "*";
        }

        // The current row is complete.
        std::cout << std::endl;
    }

    return 0;
}
