In this shot, we will discuss how to make a half pyramid pattern with stars in C++.


# Solution approach
We will use a nested loop to make the half pyramid pattern in C++. 
A **nested loop** refers to a loop inside another loop.

Let's look at an image of the pattern that we will generate. 

We will give input as a `number` to generate a half pyramid pattern.

We will pass a condition in the outer `for` loop, then in the inner `for` loop and then print `*` as the output. The most important thing that we need to see is the use of `endl`.

Let's look at the code snippet below to understand this better.  

#include <iostream>
using namespace std;

int main() {
  int number;
  cin >> number ;
  for (int i=1; i<=number; i++)
  {
    for (int j=1; j<=i ; j++)
    {
      cout << " * ";
    }
  cout << endl;
  }  
  
  return 0;
}

# Explanation
> Please enter a number above to generate an output.

* In *line 5,* we have initialized a variable `number`. 

* In *line 6*, we take the input as `number`. 

* In *line 7*, we have initialized an *outer* `for` loop, where we have given a condition to run the loop for `number` times.

* In *line 9*, we have initialized an *inner* `for` loop, where we have given conditions to run the loop for `i` times.

* In *line 11*, we have given a condition to print `*`. It will print for `i` times, as given in the condition.

* In *line 13*, we print a next line character. This is done so that the star gets printed now from the next line onwards.


In this way, we can use loops to make a half pyramid pattern in C++.
