C++ Program for Expressionless Face Pattern printing
Given a number n; the task is to create the Expressionless face pattern upto n lines and display the results. Expressionless face is created using special characters, expressionless face using special character seems like: “*_*”.
Example
Input-: n = 6 Output-:
Input-: n = 8 Output-:
Algorithm
Start Step 1-> In function print_stars(int i) Loop For j = 1 and j <= i and j++ Print “*” Step 2-> In function print_pattern(int rows) Loop For i = 1 and i <= rows and i++ Call function print_stars(i) Print “_” Call print_stars(rows - i + 1) Print “_” Call print_stars(rows - i + 1) Print ”_” Call print_stars(i) Print newline Step 3-> In function int main() Declare and set rows = 8 Call print_pattern(rows) Stop
Example
#include <bits/stdc++.h>
using namespace std;
//function to print stars
void print_stars(int i) {
for (int j = 1; j <= i; j++)
cout << "*";
}
void print_pattern(int rows) {
for (int i = 1; i <= rows; i++) {
print_stars(i);
cout << "_";
print_stars(rows - i + 1);
cout << "_";
print_stars(rows - i + 1);
cout << "_";
print_stars(i);
cout << endl;
}
}
int main() {
int rows = 8;
print_pattern(rows);
return 0;
}Output
