# Program to Print Pyramid Pattern using numbers

• Difficulty Level : Basic
• Last Updated : 22 Apr, 2021

Given a number N denoting the number of rows. The task is to print the zigzag pattern with N rows as shown in the below examples.
Examples:

Input : 2
Output :        1
2       3

Input : 5
Output :                1
2       6
3       7       10
4       8       11      13
5       9       12      14      15

Approach:
1. Use a for loop for printing the number of rows.
2. Use two for loops for printing space and pattern.
3. Calculate starting value for each row with variable t.
Below is the implementation of above approach:

## C++

 // C++ Program to print pyramid// pattern using numbers#include using namespace std;// Function to print pyramid patternclass gfg{ public : void printPattern(int n) {    int t;     // outer loop to print rows    for (int i = 1; i <= n; i++) {         // inner loop to print spaces        for (int j = i; j < n; j++)            printf("\t");         // calculate initial value        t = i;         // inner loop to print pattern        for (int k = 1; k <= i; k++) {            printf("%d\t\t", t);            t = t + n - k;        }        printf("\n");    } }}; // Driver codeint main(){    gfg g;    int n = 6;    g.printPattern(n);    return 0;}//this code is contributed by Soumik
