C Program to Print Right Triangle of Fibonacci Series Numbers Pattern

Write a C program to print right triangle of Fibonacci series numbers pattern using for loop.

#include <stdio.h>

int main()
{
	int rows;

	printf("Enter Right Triangle Fibonacci Numbers Rows = ");
	scanf("%d", &rows);
		
	printf("The Right Triangle of Fibonacci Series Numbers Pattern\n");
	
	for(int i = 1; i <= rows; i++)  
	{
		int First_Value = 0;
		int Second_Value = 1;

		for (int j = 1; j <= i; j++)
		{
			int Next = First_Value + Second_Value;
			printf("%d ", Next);
			First_Value = Second_Value;
			Second_Value = Next;
		}
		printf("\n");
	}
}

This C program prints the right angled triangle of numbers in the Fibonacci series pattern using a while loop.

#include <stdio.h>

int main()
{
	int rows, i, j, First_Value, Second_Value, Next;

	printf("Enter Right Triangle Fibonacci Numbers Rows = ");
	scanf("%d", &rows);
		
	printf("The Right Triangle of Fibonacci Series Numbers Pattern\n");
	i = 1;
		
	while(i <= rows)  
	{
		First_Value = 0;
		Second_Value = 1;
		j = 1;
		
		while (j <= i)
		{
			Next = First_Value + Second_Value;
			printf("%d ", Next);
			First_Value = Second_Value;
			Second_Value = Next;
			j++;
		}
		printf("\n");
		i++;
	}
}
