Answer 1

Answer:

// C++ implementation to print the following

// pyramid pattern

#include <bits/stdc++.h>

using namespace std;

// function to print the following pyramid pattern

void printPattern(int n)

{

int j, k = 0;

// loop to decide the row number

for (int i=1; i<=n; i++)

{

// if row number is odd

if (i%2 != 0)

{

// print numbers with the '*' sign in

// increasing order

for (j=k+1; j<k+i; j++)

cout << j << "*";

cout << j++ << endl;

// update value of 'k'

k = j;

}

// if row number is even

else

{

// update value of 'k'

k = k+i-1;

// print numbers with the '*' in

// decreasing order

for (j=k; j>k-i+1; j--)

cout << j << "*";

cout << j << endl;

}

}

}

// Driver program to test above

int main()

{

int n = 5;

printPattern(n);

return 0;

}
