In this post, we will learn how to print odd numbers from 1 to 100 using C++ Programming language.
Any number which is not exactly divisible by 2 is called odd numbers. For example: 3, 12, 27, and so on.
We will find odd numbers by checking whether the numbers are divisible by 2 or not. We will perform this task using following methods:
- Using For Loop
- Using While Loop
- Using Do While Loop
So, without further ado, let’s begin this tutorial.
C++ Program to Print Odd Numbers From 1 To 100 Using For Loop
// C++ Program To Print Odd Numbers From 1 To 100
#include <iostream>
using namespace std;
int main(){
int i;
cout << "Odd numbers between 1 to 100 are: " << endl;
for (i = 1; i <= 100; i++){
if (i % 2 != 0)
cout << i << " ";
}
return 0;
}
Output
Odd numbers between 1 to 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
How Does This Program Work ?
int i;
In this program, we have defined a variable named i.
for (i = 1; i <= 100; i++){
if (i % 2 != 0)
cout << i << " ";
}
Then, we find all the odd numbers less than 100 using for loop statement. And the odd numbers are displayed on the screen using cout statement.
C++ Program to Print Odd Numbers From 1 To 100 Using While Loop
// C++ Program to Print Odd Numbers From 1 To 100 Using While Loop
#include <iostream>
using namespace std;
int main(){
int i;
i = 1;
cout << "Odd Numbers between 1 to 100 are: \n";
while (i <= 100){
cout << i << " ";
i = i + 2;
}
return 0;
}
Output
Odd Numbers between 1 to 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 From 1 to 100 Using Do While Loop
// C++ Program to Print Odd Numbers From 1 to 100 Using Do While Loop
#include <iostream>
using namespace std;
int main(){
int i = 1;
cout << "Odd numbers between 1 to 100 are: " << endl;
do{
if (i % 2 == 1){
cout << i << " ";
}
i++;
}
while (i <= 100);
return 0;
}
Output
Odd numbers between 1 to 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
