# C Program to Print Triangle of Numbers in Reverse Pattern

In this tutorial, i am going to show you how to print triangle of numbers in reverse pattern in c with the help of for loop, do-while loop and while loop.

## All C Programs to Print Triangle of Numbers in Reverse Pattern

• C Program to Print Triangle of Numbers in Reverse Pattern using For Loop
• C Program to Print Triangle of Numbers in Reverse Pattern using While Loop
• C Program to Print Triangle of Numbers in Reverse Pattern using Do-While Loop

### C Program to Print Triangle of Numbers in Reverse Pattern using For Loop

```#include <stdio.h>
int main()
{
int rows;
printf("Enter Triangle of Numbers in Reverse Rows = ");
scanf("%d", &rows);
printf("Triangle of Numbers in Reverse Order Pattern\n");
for (int i = rows; i >= 1; i--)
{
for (int j = 1; j < i; j++)
{
printf(" ");
}
for (int k = i; k <= rows; k++)
{
printf("%d ", k);
}
printf("\n");
}
}```

The result of the above c program; is as follows:

```Enter Triangle of Numbers in Reverse Rows = 5
Triangle of Numbers in Reverse Order Pattern
5
4 5
3 4 5
2 3 4 5
1 2 3 4 5 ```

### C Program to Print Triangle of Numbers in Reverse Pattern using While Loop

```#include <stdio.h>
int main()
{
int i, j, k, rows;

printf("Enter Triangle of Numbers in Reverse Rows = ");
scanf("%d", &rows);
printf("Triangle of Numbers in Reverse Order Pattern\n");
i = rows;
while (i >= 1)
{
j = 1;
while (j < i)
{
printf(" ");
j++;
}
k = i;
while (k <= rows)
{
printf("%d ", k);
k++;
}
printf("\n");
i--;
}
}```

The result of the above c program; is as follows:

```Enter Triangle of Numbers in Reverse Rows = 5
Triangle of Numbers in Reverse Order Pattern
5
4 5
3 4 5
2 3 4 5
1 2 3 4 5 ```

### C Program to Print Triangle of Numbers in Reverse Pattern using Do-While Loop

```#include <stdio.h>
int main()
{
int i, j, k, rows;
printf("Enter Triangle of Numbers in Reverse Rows = ");
scanf("%d", &rows);
printf("Triangle of Numbers in Reverse Order Pattern\n");
i = rows;
do
{
j = 1;
do
{
printf(" ");
} while (j++ < i);
k = i;
do
{
printf("%d ", k);
} while (++k <= rows);
printf("\n");
} while (--i >= 1);
}```

The result of the above c program; is as follows:

```Enter Triangle of Numbers in Reverse Rows = 5
Triangle of Numbers in Reverse Order Pattern
5
4 5
3 4 5
2 3 4 5
1 2 3 4 5 ```
