In this post, we will learn how to print odd numbers between 1 to 100 using C Programming language.
Odd Numbers are the integers that always leave a remainder when divided by 2. These numbers are the integers with the form n = 2k + 1, where k is an integer.
We will be printing odd numbers using three different methods. The methods are as follows:
- Using While Loop
- Using For Loop
- Without Using If Statement
So, without further ado, let’s begin this tutorial.
C Program To Print Odd Numbers Between 1 to 100
// C Program To Print Odd Numbers Between 1 To 100
#include <stdio.h>
int main(){
int i;
printf("Odd Numbers Between 1 To 100 are: \n");
for (i = 1; i <= 100; ++i){
if (i % 2 != 0){
printf("%d\n", i);
}
}
return 0;
}
Output

How Does This Program Work ?
int i;
In this program, we have declared an int data type variable named i.
for (i = 1; i <= 100; ++i){
if (i % 2 != 0){
printf("%d\n", i);
}
}
For Loop will make sure that the number lies between 1 to 100. Then, we check whether the number is exactly divisible by 2 or not.
If the number is not exactly divisible by 2, then it means the number is an odd number. Then, we print the value of i.
After that the value of i is incremented by 1 and then the program re-checks whether it is divisible by 2 or not. If it’s not divisible, then our program will print it otherwise it will ignore it.
This process continues until i <= 100.
C Program To Print Odd Numbers Using While Loop
// C Program To Print Odd Numbers Using While Loop
#include <stdio.h>
int main(){
int i = 1, num;
// Asking for Input
printf("Enter the maximum value: ");
scanf("%d", &num);
printf("Odd Numbers from 1 to %d are: \n", num);
while (num >= i){
printf("%d\t", i);
i = i + 2;
}
return 0;
}
Output
Enter the maximum value: 14
Odd Numbers from 1 to 14 are:
1 3 5 7 9 11 13
C Program To Print Odd Numbers Using For Loop
// C Program To Print Odd Numbers
#include <stdio.h>
int main(){
int i, num;
// Asking for Input
printf("Enter the maximum value: ");
scanf("%d", &num);
printf("Odd Numbers From 1 to %d are: \n", num);
for (i = 1; i <= num; i++){
if (i % 2 != 0){
printf("%d\n", i);
}
}
return 0;
}
Output
Enter the maximum value: 20
Odd Numbers From 1 to 20 are:
1
3
5

C Program To Print Odd Numbers Without Using If Statement
// C Program To Print Odd Numbers Without If Statement

for (i = 1; i <= num; i = i + 2){
printf("%d\t", i);
}
return 0;
}
Output
Enter the maximum number: 25
Odd Numbers From 1 to 25 are:
1 3 5 7 9 11 13 15 17 19 21 23 25 C Program To Print Odd Numbers in a Given Range
// C Program To Print Odd Numbers in a Given Range
#include <stdio.h>
int main(){
int i, min, max;
// Asking for Input
printf("Enter the minimum value: ");
scanf("%d", &min);
printf("Enter the maximum value: ");
scanf("%d", &max);
if (min % 2 ==0){
min++;
}
printf("Odd Numbers from %d to %d are: \n", min, max);
for (i = min; i <= max; i++){
if (i % 2 != 0){
printf("%d\t", i);
}
}
return 0;
}
Output
Enter the minimum value: 5
Enter the maximum value: 20
Odd Numbers from 5 to 20 are:
5 7 9 11 13 15 17 19 Conclusion
