Solution:
#include <iostream>
using namespace std;
int main() {
cout << "Enter a number : ";
int n;
cin >> n;
cout << endl;
int row = 1;
while(row <= n){
// printing 1st triangle
int val1 = 1;
while(val1 <= (n - row + 1)){
cout << val1 << " ";
val1 += 1;
}
// printing 2nd triangle
int val2 = (row - 1)*2;
while(val2){
cout << "* ";
val2 -= 1;
}
// printing 3rd triangle
int val3 = n - row + 1;
while(val3){
cout << val3 << " ";
val3 -= 1;
}
row += 1;
