for ( i=0, i<5, i++)

package com.company;

public class exercises {
    public static void main(String [] args)
    {
        int sum = 0;
        int i;
        for(i=0;i<5;i++)
        {
            sum += i;
        }
        System.out.print(sum);


    }

}

32.
The print statement is not in the loop.
It needs {} brackets.

33.
i will always be larger than 10.

35.
It prints i, not the sum.

38.
Bad syntax.
switch out i<3 and i++

39.
for adds 1 to i before it prints Hello.
So you need an extra iteration.
Lower i to 0 or raise its constraint to 4.

40.
for statement needs semicolons.

41. i isnt declared as an integer.

42. i doesnt need value assignment, just declaration.
