C Program to Print Odd Numbers from 1 to N

How to write a C Program to Print Odd Numbers from 1 to N using For Loop and While Loop?.

C Program to Print Odd Numbers from 1 to N using For Loop

This C program to display Odd Numbers from 1 to N allows the user to enter the maximum limit value. Next, it is going to print the list of all odd numbers from 1 to user-entered value.

```/* C Program to Print Odd Numbers from 1 to N using For Loop and If */

#include<stdio.h>

int main()
{
int i, number;

printf("\n Please Enter the Maximum Limit Value :  ");
scanf("%d", &number);

printf("\n Odd Numbers between 1 and %d are : \n", number);
for(i = 1; i <= number; i++)
{
if ( i % 2 != 0 )
{
printf(" %d\t", i);
}
}

return 0;
}```

Within this Program to Print Odd Numbers from 1 to N example, For Loop will make sure that the number is between 1 and maximum limit value.

```for(i = 1; i <= number; i++)
```

In the Next line, We declared the If statement

`if ( number % 2 != 0 )`

Any number that is not divisible by 2 is an Odd number. If condition will check whether the remainder of the number divided by 2 is not equal to 0 or not. If the condition is True, then it is an Odd number, and the compiler will print i value.

Program to Print Odd Numbers from 1 to N without If Statement

This program to Print Odd Numbers from 1 to N in c is the same as the above but, we just altered the for loop to eliminate If statement.

If you observe the below C Programming code snippet, We started i from 1 and incremented it by 2 (not 1). It means, for the first iteration, i will be 1, and for the second iteration, i will be 3 (not 2), etc.

```#include<stdio.h>

int main()
{
int i, number;

printf("\n Please Enter the Maximum Limit Value : ");
scanf("%d", &number);

printf("\n Odd Numbers between 1 and %d are : \n", number);
for(i = 1; i <= number; i= i+2)
{
printf(" %d\t", i);
}

return 0;
}```
`````` Please Enter the Maximum Limit Value : 18

Odd Numbers between 1 and 18 are :
1	 3	 5	 7	 9	 11	 13	 15	 17	``````

C Program to Print Odd Numbers from 1 to 100 using While Loop

This Print Odd Numbers from 1 to N is the same as above. We just replaced the For Loop with While Loop.

```#include<stdio.h>

int main()
{
int i = 1, number;

printf("\n Please Enter the Maximum Limit Value : ");
scanf("%d", &number);

printf("\n Odd Numbers between 1 and %d are : \n", number);
while(i <= number)
{
printf(" %d\t", i);
i = i + 2;
}

return 0;
}```

C odd numbers from 1 to 100 output

`````` Please Enter the Maximum Limit Value : 100

Odd Numbers between 1 and 100 are :
1	 3	 5	 7	 9	 11	 13	 15	 17	 19	 21	 23	 25	 27	 29	 31	 33	 35	 37	 39	 41	 43	 45	 47	 49	 51	 53	 55	 57	 59	 61	 63	 65	 67	 69	 71	 73	 75	 77	 79	 81	 83	 85	 87	 89	 91	 93	 95	 97	 99	``````

C Program to Print Odd Numbers in a Given Range

This program allows the user to enter Minimum and maximum value. Next, the C program will print a list of all even numbers between Minimum value and maximum value.

```#include<stdio.h>

int main()
{
int i, Minimum, Maximum;

printf("\n Please Enter the Minimum Limit Value :  ");
scanf("%d", &Minimum);

printf("\n Please Enter the Maximum Limit Values :  ");
scanf("%d", &Maximum);

if ( Minimum % 2 == 0 )
{
Minimum++;
}

printf("\n Odd Numbers between %d and %d are : \n", Minimum, Maximum);
for(i = Minimum; i <= Maximum; i= i+2)
{
printf(" %d\t", i);
}

return 0;
}```
`````` Please Enter the Minimum Limit Value :  14

Please Enter the Maximum Limit Values :  125

Odd Numbers between 15 and 125 are :
15	 17	 19	 21	 23	 25	 27	 29	 31	 33	 35	 37	 39	 41	 43	 45	 47	 49	 51	 53	 55	 57	 59	 61	 63	 65	 67	 69	 71	 73	 75	 77	 79	 81	 83	 85	 87	 89	 91	 93	 95	 97	 99	 101	 103	 105	 107	 109	 111	 113	 115	 117	 119	 121	 123	 125``````
