Introduction
I have used CodeBlocks compiler for debugging purpose. But you can use any C++ programming language compiler as per your availability.
Write C++ program to find sum of odd numbers between 1 to n
#include <iostream>
using namespace std;
int main()
{
int i, num, sum=0;
//Reading number
cout<<"Enter any number: "<<endl;
cin>>num;
for(i=1; i<=num; i+=2)
{
//Adding current even number to sum variable
sum += i;
}
cout<<"Sum of all odd number between 1 to " << num << ": "<<sum;
return 0;
}
Result
