Question

So, I have solved void pattern 2. Void pattern 1 I am having a bit of trouble being able to turn my center column in to exponents of 2. Not exactly sure how to do it, and a pointer in the right direction would help a ton

Programming Questions: 01 (Display numbers in a pyramid pattern). Using nested loop, write a complete and commented C++ program using patternl function and pattern2 function to print the following patterns: void pattern2 (int rows 12 48 16 8 4 2 1 1 24 8 16 32 16 8 2 1 1 2 4 8 16 32 64 32 16 8 42 1 1 2 4 8 16 32 64 128 64 32 16 84 2 1 Make sure that your program prompts the user to enter number of rows.

Explanation / Answer

// C++ code to demonstrate star pattern

#include <iostream>

#include <bits/stdc++.h>

using namespace std;

// Function to demonstrate printing pattern

void triangle(int n)

{

// number of spaces

int k = 4*n-4;

int l=0;

// outer loop to handle number of rows

// n in this case

for (int i=0; i<n; i++)

{

// inner loop to handle number spaces

// values changing acc. to requirement

for (int j=0; j<k; j++)

cout <<" ";

// decrementing k after each loop

k = k - 4;

// inner loop to handle number of columns

// values changing acc. to outer loop

l=0;

for (int j=0; j<=2*i; j++ )

{

// printing stars

if(j<i){

cout.width(4);

cout<<(int)pow(2,l++);}

else{

cout.width(4);

cout <<(int)pow(2,l--);

}

}

// ending line after each row

cout << endl;

}

}

// Driver Function

int main()

{

int n = 8;

triangle(n);

return 0;

}
