Write a C++ program to shown 20 even number of while using do-while loop?

Tanmoy Mistri answered

You're question is not clear.Well here's a sample program that'll print even numbers between 1 and 20.

#include<iostream.h>
void main()
{
int I=1;
cout<<"Even numbers between 1 and 20n";
do{
if(I%2==0)
cout<<I<<"n";
I++;
}while(I<=20) ;
}

#include <iostream>

using namespace std;

int main()

{

int number =
1;

while (number
<= 21 && number / 2)

{

cout
<< number;

number++;

}

return 0;

}
