# C Program to Print Pyramid Numbers Pattern

Write a C program to print a pyramid numbers pattern using nested for loop or a program to print a pyramid pattern of numbers.

#include <stdio.h>

int main()
{
int rows;

printf("Enter Pyramid Number Pattern Rows = ");
scanf("%d", &rows);

printf("Printing Pyramid Number Pattern\n");

for (int i = 1; i <= rows; i++)
{
for (int j = rows; j > i; j--)
{
printf(" ");
}
for (int k = 1; k <= i; k++)
{
printf("%d ", i);
}
printf("\n");
}
}

This C program helps to print a pyramid pattern of numbers using a while loop.

#include <stdio.h>

int main()
{
int i, j, k, rows;

printf("Enter Pyramid Number Pattern Rows = ");
scanf("%d", &rows);

printf("\n");

i = 1;

while (i <= rows)
{
j = rows;
while (j > i)
{
printf(" ");
j--;
}

k = 1;
while (k <= i)
{
printf("%d ", i);
k++;
}

printf("\n");
i++;
}
}

This example uses the do while loop to print the pyramid pattern of numbers.

#include <stdio.h>

int main()
{
int i, j, k, rows;

printf("Enter Rows = ");
scanf("%d", &rows);

printf("\n");

i = 1;

do
{
j = rows;
do
{
printf(" ");

} while (j-- > i);

k = 1;
do
{
printf("%d ", i);

} while (++k <= i);

printf("\n");

} while (++i <= rows);
}
Enter Rows = 9
