Generate a half pyramid pattern with stars in C++
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;}
Enter the input below
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
forloop, where we have given a condition to run the loop fornumbertimes. -
In line 9, we have initialized an inner
forloop, where we have given conditions to run the loop foritimes. -
In line 11, we have given a condition to print
*. It will print foritimes, 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++.
