用C++打印金字塔图案的程序

本文旨在提供用于图案打印的C++实现。

• 简单的金字塔图案

CPP

// C++ code to demonstrate star pattern
#include 
using namespace std;
 
// Function to demonstrate printing pattern
void pypart(int n)
{
    // Outer loop to handle number of rows
    // n in this case
    for (int i = 0; i < n; i++) {
 
        // Inner loop to handle number of columns
        // values changing acc. to outer loop
        for (int j = 0; j <= i; j++) {
 
            // Printing stars
            cout << "* ";
        }
 
        // Ending line after each row
        cout << endl;
    }
}
 
// Driver Function
int main()
{
    int n = 5;
    pypart(n);
    return 0;
}
