Hey can you please tell me what I did wrong?

Question

I have to create a program in java with ,,do while, for” , and the output has to be all even-numbers ,,2,4,6,8...n”.

{
int n,d,b,i=0;
for(b=1;i<=n;b++)
{ d=2;
while((d<b)&&(d%b!=0))
d++;
if (d==b)
{ cout <<b;
i+=1;
}
}
}

Answer 1

Hello Ariadna Topala

cout << is c++ not java.

In java you have to use System.out.print() or System.out.println().

Answer 2

so what should I do? I tried changing it but it gave me error

Answer 3

//System.out.println("Enter the number : ");
Scanner sc = new Scanner(System.in);
int n = sc.nextInt();

///////////////////// with for loop ;
System.out.println("with for loop");
for(int i =1 ;i<=n ; i++) {
if(i%2==0)System.out.println(i);
}

//////////////////// withe do while loop ;
System.out.println("with do while loop");
int i = 1 ;
do{if(i%2==0)System.out.println(i);
i++;
}
while(i<=n);
