C :

#include<stdio.h>

void main(){
	int n,i,g;
	scanf("%d",&n);
	
	i=1;
	while(i<=n){
		g=i%10;
		if(g==1||g==3||g==5||g==7){
			printf("%d\n",i);
		}
		i++;
	}
} 

C++ :

#include <bits/stdc++.h>
using namespace std;

int main() {
	int i,n,g;
	cin>>n;
	i = 1;
	while(i <= n){
		g = i % 10;
		if(g == 1 || g == 3 || g == 5 || g == 7){
			cout<<i<<endl;
		}
		i = i + 1;
	}
}

Java :

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		int n = sc.nextInt();
		for(int i=1;i<=n;i++) {
			int g = i % 10;
			if(g==1 || g==3 || g==5 || g==7) {
				System.out.println(i);
			}
		}

	}

}

Python :

#接收输入整数
n = int(input())
#从1~n的for循环
for i in range(1, n + 1):
    #计算个位数值
    gw = i % 10
    #如果个位数=1 或=3 或=5 或=7时，打印此时的i值
    if gw == 1 or gw == 3 or gw == 5 or gw == 7:
        print(i)
