In this example, you will learn a C++ program to print Floyd’s triangle. Floyd’s triangle is a right-angle triangle of natural numbers whose all sides are equal. This program takes maximum rows from the user and prints Floyd’s triangle on the console screen.
Example: Floyd’s triangle in C++
//C++ program to print Floyd triangle
#include <iostream>
using namespace std;
int main()
{
int totalRows, j, k, count = 1;
cout <<"Enter total number of rows to print: ";
cin >> totalRows;
for (j = 1; j <= totalRows; j++)
{
for (k = 1; k <= j; k++)
{
cout << count;
count++;
}
cout << endl;
}
return 0;
}Output
