WAP to print the following series. 1 3 5 7... n
Objective
Write a C++ program to print the odd number series: 1, 3, 5, 7 ... N.
Algorithm / Approach
- Read an integer
n. - Start a
forloop withi = 1. - Increment the loop by 2:
i = i + 2. - Print
i.
main.cpp
#include<iostream>
using namespace std;
int main() {
int n;
cout<<"Enter the Value for N : ";
cin>>n;
for(int i = 1; i<=n; i=i+2) {
cout<< i<<" ";
}
cout<< endl;
return 0;
}Expected Output
Enter the Value for N : 20 1 3 5 7 9 11 13 15 17 19
Explanation of the Program
- This uses the exact same step-logic as the even number series.
- The only difference is the starting point. By starting at 1 and jumping by 2, you perfectly land on all the odd numbers.
