This program generates a left arrow pattern based on the number of rows specified by the user. The pattern is symmetric, with a top half and a bottom half.
#include <iostream>
using namespace std;
int main() {
// Get the number of rows from the user
int num_rows;
cout << "Enter the number of rows: ";
cin >> num_rows;
// Display the left arrow pattern
for (int i = 1; i <= num_rows; i++) {
for (int j = 1; j <= num_rows - i; j++) {
cout << " ";
}
for (int k = 1; k <= i; k++) {
cout << "*";
}
cout << endl;
}
for (int i = num_rows - 1; i >= 1; i--) {
for (int j = 1; j <= num_rows - i; j++) {
cout << " ";
}
for (int k = 1; k <= i; k++) {
cout << "*";
}
cout << endl;
}
return 0;
}

In this code, the user is prompted to enter the number of rows for the left arrow pattern. The first for
loop is responsible for printing the top half of the pattern, and the second for
loop prints the bottom half.
The inner for
loops within each outer loop are used to print spaces and asterisks (*) for each row. The cout << " ";
statement prints a space, and the cout << "*";
statement prints an asterisk. The endl
statement is used to move to the next line after each row.
