How to print odd numbers ( 1 -> 10) by do - while

Question

How to print odd numbers ( 1 -> 10) by do - while?

#include <stdio.h>
#include <conio.h>
 int i;
void Dayso()
{

    do 
    {
        i = 1
        i++;
        if ( i % 2 == 0 )
        {
            continue;
        }
        printf ("\n%d",i);

    }while (i <= 10 );

}

int main()
{
    Dayso ();
    getch();
    return 0;
}

and the output:

Line 18: error: conio.h: No such file or directory
In function 'Dayso':
Line 10: error: expected ';' before 'i'

How do I fix this?

The error messages are way clear: start adding a `;` at the end of row 9. About the error `Line 18: error: conio.h: No such file or directory`, [this might help you]http://stackoverflow.com/questions/8792317/why-cant-i-find-conio-h-on-linux). — il_raffa, Aug 15 '15 at 07:13
What is the very first thing done in the loop body (and thus done every loop)? Why (is this a problem)? — user2864740, Aug 15 '15 at 07:18

Compile errors:

There is no conio.h header file in Linux machines. You can remove getch() function in this program.
You are missing semicolon in line 9.

Logic errors:

You are assigning 1 to i variable (9 line) on every do while iteration so you have just created infinite cycle. Move assignment to 1 outside the loop.
You are missing 1 from ods and 11 gets printed in current implementation.

Corrected solution: http://ideone.com/IB3200

#include <stdio.h>

void Dayso()
{
    int i = 1;
    do 
    {
        if ( i % 2 != 0 ) {
            printf ("\n%d",i);
        }

        i++;
    } while (i <= 10 );

}

int main()
{
    Dayso ();
    return 0;
}

int a = 2;

    do {
        System.out.println(a);
            a++;
        if (a%2==0);
        a++;
    }

    while (a <= 20);
    }
}

The edit queue is full so I cant fix the obvious errors: starting at ` a =2` and continuing to `a <= 20` means you miss 1 and get 11/13/15/17/19 - so you haven't answered the question... likewise, the question is tagged `C` not java. – Andrew Feb 28 '22 at 10:11
