C :

#include<stdio.h>

void main(){
	int i,g,s;
	
	i=10;
	while(i<=99){
		g=i%10;
		s=i/10%10;
		if(g==2||s==2){
			printf("%d\n",i);
		}
		i++;
	}
}

C++ :

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

int main() {
	int i,n,g,s;
	i = 10;
	while(i <= 99){
		g = i % 10;
		s = i / 10;
		if(g == 2 || s == 2){
			cout<<i<<endl;
		}
		i = i + 1;
	}
}

Pascal :

var a,b,i:longint;
begin
for i:=10 to 99 do
begin
a:=i mod 10;
b:=i div 10;
if (a=2) or (b=2) then writeln(i);
end;
end.

Java :

public class Main {

	public static void main(String[] args) {
		for(int i=10;i<=99;i++) {
			int g = i % 10;
			int s = i / 10;
			if(g==2 || s==2) {
				System.out.println(i);
			}
		}

	}

}

Python :

for i in range(10, 100):
    sw = i // 10 % 10
    gw = i // 1 % 10
    if sw == 2 or gw == 2:
        print(i)
