Write a C program to print inverted triangle numbers pattern using for loop.
#include <stdio.h>
int main()
{
int rows;
printf("Enter Inverted Triangle Number Pattern Rows = ");
scanf("%d", &rows);
printf("Printing Inverted Triangle Number Pattern\n");
for (int i = 1; i <= rows; i++)
{
for (int j = 1; j < i; j++)
{
printf(" ");
}
for (int k = 1; k <= rows - i + 1; k++)
{
printf("%d ", k);
}
printf("\n");
}
}
This C example displays the inverted triangle pattern of numbers using a while loop.
#include <stdio.h>
int main()
{
int rows, i, j, k;
printf("Enter Inverted Triangle Number Pattern Rows = ");
scanf("%d", &rows);
printf("Printing Inverted Triangle Number Pattern\n");
i = 1;
while (i <= rows)
{
j = 1;
while (j < i)
{
printf(" ");
j++;
}
k = 1;
while (k <= rows - i + 1)
{
printf("%d ", k);
k++;
}
printf("\n");
i++;
}
}
Enter Inverted Triangle Number Pattern Rows = 9

1 2 3 4 5 6 7 8

1 In this pattern example, we used the do while loop to display the inverted triangle of numbers.
#include <stdio.h>
int main()
{
int rows, i, j, k;
printf("Enter Inverted Triangle Number Pattern Rows = ");
scanf("%d", &rows);
printf("Printing Inverted Triangle Number Pattern\n");
i = 1;
do
{
j = 1;
do
{
printf(" ");
} while (j++ < i);
k = 1;
do
{
printf("%d ", k);
} while (++k <= rows - i + 1);
printf("\n");
} while (++i <= rows);
}
Enter Inverted Triangle Number Pattern Rows = 6
