Write a C++ Program to find the sum of odd numbers from 0 to n. This C++ program allows you to enter the maximum odd number. Next, we used the for loop (for(number = 1; number <= maximum; number++)) to iterate numbers from 1 to maximum. We used the If condition (if ( number % 2 != 0 ) ) within the loop to check whether the number % 2 not equals 0. If true, add that odd number to the sum value, and print it as the odd number. Next, it prints the sum of the odd numbers as a result.

#include<iostream> using namespace std; int main() { int number, maximum, sum = 0; cout << "\nPlease Enter the Odd Numbers Maximum Limit = "; cin >> maximum; cout <<"\n\nOdd Numbers between 0 and " << maximum << " = "; for(number = 1; number <= maximum; number++) { if ( number % 2 != 0 ) { cout << number << " "; sum = sum + number; } } cout << "\nThe Sum of All Odd Numbers upto " << maximum << " = " << sum; return 0; }

## C++ Program to find Sum of Odd Numbers Example 2

In this C++ program to calculate the sum of odd Numbers, we altered the for loop (for(number = 1; number <= maximum; number = number + 2)) to remove the If condition. As you can see, we incremented the number by 2 (instead of 1 number++). As we know, every number starts from 1 with an increment of 2 (1 + 2 = 3) will be an odd number. So, we add that odd number to the sum and print the sum as a result.

#include<iostream> using namespace std; int main() { int number, maximum, sum = 0; cout << "\nPlease Enter the Odd Numbers Maximum Limit = "; cin >> maximum; cout <<"\n\nOdd Numbers between 0 and " << maximum << " = "; for(number = 1; number <= maximum; number = number + 2) { sum = sum + number; cout << number << " "; } cout << "\nThe Sum of All Odd Numbers upto " << maximum << " = " << sum; return 0; }

```
Please Enter the Odd Numbers Maximum Limit = 20
Odd Numbers between 0 and 20 = 1 3 5 7 9 11 13 15 17 19
The Sum of All Odd Numbers upto 20 = 100
```

This C++ sum of odd numbers example allows the user to enter the minimum and maximum value. Next, it will calculate the sum of odd numbers from minimum to maximum.

#include<iostream> using namespace std; int main() { int number, minimum, maximum, sum = 0; cout << "\nPlease Enter the Odd Numbers Minimum Limit = "; cin >> minimum; cout << "Please Enter the Odd Numbers Maximum Limit = "; cin >> maximum; cout <<"\nOdd Numbers between " << minimum << " and " << maximum << " = "; for(number = minimum; number <= maximum; number++) { if ( number % 2 != 0 ) { cout << number << " "; sum = sum + number; } } cout << "\nThe Sum of All Odd Numbers from " << minimum << " to " << maximum << " = " << sum; return 0; }

```
Please Enter the Odd Numbers Minimum Limit = 50
Please Enter the Odd Numbers Maximum Limit = 70
Odd Numbers between 50 and 70 = 51 53 55 57 59 61 63 65 67 69
The Sum of All Odd Numbers from 50 to 70 = 600
```
