C++ :

#include<bits/stdc++.h>
using namespace std;
int a,b;
int main()
{
	for(int i=1;i<100;i+=2)
		cout<<i<<endl;
	return 0;
}

Pascal :

var
i:integer;
begin
 for i:= 1 to 100 do
 if i mod 2=1 then writeln(i);
end.

Java :

import java.util.Scanner;

public class Main {
  public static void main(String[] args) {
    Scanner cin = new Scanner(System.in);
    int n=100;
    int i;
      for (i = 1; i <= n; i++)
        if (i % 2 != 0) {
          System.out.println(i);
        }
    }
  }
