推荐：请在"实践首先, 在继续解决方案之前。以下程序将打印出n条线的弗洛伊德三角形。
C ++

#include < bits/stdc++.h> using namespace std; void printFloydTriangle( int n) { int i, j, val = 1; for (i = 1; i < = n; i++) { for (j = 1; j < = i; j++) cout < < val++ < < " " ; cout < < endl; } } // Driver Code int main() { printFloydTriangle(6); return 0; } // This is code is contributed // by rathbhupendra

// Without using a temporary variable and with only one loop #include< stdio.h> void floyd(n){ int i, j=1; for (i=1; i< =(n*(n+1))/2; i++){ printf ( "%d " , i); if (i==(j*(j+1))/2){ printf ( "\n" ); j++; } } }int main(){ floyd(6); }//This code is contributed by Vishal B

Java

// Java program to print // Floyd's triangle class GFG { static void printFloydTriangle( int n) { int i, j, val = 1 ; for (i = 1 ; i < = n; i++) { for (j = 1 ; j < = i; j++) { System.out.print(val + " " ); val++; } System.out.println(); } }// Driver Code public static void main(String[] args) { printFloydTriangle( 6 ); } }

Python3

# Python3 program to print # Floyd's triangle def loydTriangle(n):val = 1 for i in range ( 1 , n + 1 ):for j in range ( 1 , i + 1 ): print (val, end = " " ) val + = 1print ("")loydTriangle( 6 )# This code is contributed by # Smitha Dinesh Semwal

// C# program to print // Floyd's triangle using System; class GFG { static void printFloydTriangle( int n) { int i, j, val = 1; for (i = 1; i < = n; i++) { for (j = 1; j < = i; j++) { Console.Write(val + " " ); val++; } Console.WriteLine(); } }// Driver Code public static void Main() { printFloydTriangle(6); } }

的PHP

< ?php // PHP code to print Floyd's Triangle// Function to display Floyd's Triangle function FloydsTriangle( $n ) { $val = 1; // loop for number of lines for ( $i = 1; $i < = $n ; $i ++) { // loop for number of elements // in each line for ( $j = 1; $j < = $i ; $j ++) { print ( $val . " " ); $val ++; } print ( "\n" ); } }// Driver's Code $n = 6; FloydsTriangle( $n ); // This code is contributed by akash7981 ?>

输出如下：
