# C Program to Print First N Odd Natural Numbers

In this tutorial, i am going to show you how to print first n (10, 100, 1000 .. N) odd natural numbers in the c program using for loop, while and loop.

## Algorithm and Programs to Print First N Odd Natural Numbers in C

• Algorithm to Print First N Odd Natural Numbers
• C Program to Print First N Odd Natural Numbers using For Loop
• C Program to Print First N Odd Natural Numbers using While Loop

### Algorithm to Print First N Odd Natural Numbers

Follow the below given algorithm to write a program to find and print first n(10, 100, 1000 .. N) odd natural numbers; as follows:

• Step 1: Start Program.
• Step 2: Read the a number from user and store it in a variable.
• Step 3: Find first n odd natural number using for loop or while loop or do while loop.
• Step 4: Print first n odd natural number.
• Step 5: Stop Program.

### C Program to Print First N Odd Natural Numbers using For Loop

```#include <stdio.h>
void main()
{
int i,n;
printf("Input number of terms : ");
scanf("%d",&n);
printf("\nThe Odd numbers are :");
for(i=1;i<=n;i++)
{
printf("%d ",2*i - 1);
}
} ```

The result of the above c program; as follows:

```Input number of terms : 5
The Odd numbers are :1 3 5 7 9 ```

### C Program to Print First N Odd Natural Numbers using While Loop

```#include <stdio.h>
void main()
{
int i,n;
printf("Input number of terms : ");
scanf("%d",&n);
printf("\nThe odd numbers are :");

i = 1;
while (i <= n)
{
printf("%d ", 2 * i - 1);
i++;
}
} ```

The result of the above c program; as follows:

```Input number of terms : 10
The odd numbers are :1 3 5 7 9 11 13 15 17 19 ```
