In this article we will show you, 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 program allows the user to enter the maximum limit value. Next, it is going to print list of all odd numbers from 1 to user entered value.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |
/* 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; } |

ANALYSIS
Here, For Loop will make sure that the number is between 1 and maximum limit value.
|
1 |
for(i = 1; i <= number; i++) |
In the Next line, We declared the If statement
|
1 |
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.
C Program to Print Odd Numbers from 1 to N without If Statement
This program is same as the above but, we just altered the for loop to eliminate If statement.
If you observe the below code snippet, We started i from 1 and increment 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) so on.

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

/* C Program to Print Odd Numbers from 1 to N using 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; } |
OUTPUT
C Program to Print Odd Numbers in a Given Range
This program allows the user to enter Minimum and maximum value. Next, the program will print list of all even numbers between Minimum value and maximum value.

/* C Program to Print Even Numbers within a Range */ #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; } |
