Given the value of n, i.e, number of lines, print the pattern.
Examples :
Input : n = 5 Output : *_*****_*****_* **_****_****_** ***_***_***_*** ****_**_**_**** *****_*_*_***** Input : n = 10 Output : *_**********_**********_* **_*********_*********_** ***_********_********_*** ****_*******_*******_**** *****_******_******_***** ******_*****_*****_****** *******_****_****_******* ********_***_***_******** *********_**_**_********* **********_*_*_**********
C++
// C++ implementation to print the pattern #include <bits/stdc++.h> using namespace std; // Function to print required // number of stars void print1(int i) { for (int j = 1; j <= i; j++) cout << "*"; } void print(int n) { for (int i = 1; i <= n; i++) { // function calling to print // the initial stars in each line print1(i); // printing underscore cout << "_"; // function calling to print // stars on right side of first half print1(n - i + 1); // printing underscore cout << "_"; // function calling to print // stars on left side of second half print1(n - i + 1); // printing underscore cout << "_"; // function calling to print // the ending stars print1(i); cout << endl; } } // Driver code int main() { // number of lines int n = 5; // function calling print(n); return 0; } |
