Write a C++ program to print right arrow number pattern using for loop.
#include<iostream> using namespace std; int main() { int i, j, rows; cout << "Enter Right Arrow Number Pattern Row = "; cin >> rows; cout << "Right Arrow Number Pattern\n"; for(i = 1; i <= rows; i++) { for(j = 1; j <= rows; j++) { if(j < i) { cout << " "; } else { cout << j; } } cout << "\n"; } for(i = 1; i < rows; i++) { for(j = 1; j <= rows; j++) { if(j < rows - i) { cout << " "; } else { cout << j; } } cout << "\n"; } return 0; }

This C++ example prints the numbers in a right arrow pattern using a while loop.
#include<iostream> using namespace std; int main() { int i = 1, j, rows; cout << "Enter Right Arrow Number Pattern Row = "; cin >> rows; cout << "Right Arrow Number Pattern\n"; while(i <= rows) { j = 1; while( j <= rows) { if(j < i) { cout << " "; } else { cout << j; } j++; } cout << "\n"; i++; } i = 1; while( i < rows) { j = 1; while( j <= rows) { if(j < rows - i) { cout << " "; } else { cout << j; } j++; } cout << "\n"; i++; } return 0; }
Enter Right Arrow Number Pattern Row = 9
