Full Pyramid Pattern of Numbers

Full Pyramid Pattern of Numbers
A full pyramid pattern of numbers is similar to an equilateral triangle.

Examples: 

        1 
      2 2 2 
    3 3 3 3 3 
  4 4 4 4 4 4 4 
5 5 5 5 5 5 5 5 5 

// C program to print the full pyramid pattern of alphabets
#include <stdio.h>

int main()
{
	int rows;
	printf("Number of rows: ");
	scanf("%d", &rows);

	// first loop to print all rows
	for (int i = 1; i <= rows; i++) {

		// inner loop 1 to print white spaces
		for (int j = 1; j <= 2 * (rows - i); j++) {
			printf(" ");
		}

		// inner loop 2 to print numbers
		for (int k = 1; k < 2 * i; k++) {
			printf("%d ", i);
		}
		printf("\n");
	}
	return 0;
