Floating point variables conversion109

What will be the output of the following program?

class FloatConversion
{
    public static void main(String args[])
    {
        int i = 44;
        float f = 98.42f;
        double d = 103.67;
        
        f = i;
        d = f;
        i = (int) d;

        System.out.println("i = " + i);
        System.out.println("f = " + f);
        System.out.println("d = " + d);
    }
}

A.	i = 44 f = 44.0 d = 44.0
B.	i = 103.67 f = 44 d = 98.42
C.	i = 44 f = 44 d = 44
D.	i = 44.0 f = 44.0 d = 44.0

Find if the word present in character matrix BiDirectional

Write a program to find if the word is present in the character matrix in any direction. The directions are horizontal, vertical, upward diagonal, downward diagonal and their opposite directions.

Input (char[][], String)	Output (Boolean)
`B A T C T O P C X Y Z W A C W Z search word = TOP`	true
`B A T C T O P C X Y Z W A C W Z search word = POT`	true
`Q E A R M I X Y Z search word = MAT`	false
`Q E A D R B E G J I W Z A L N X V M S U C J O P T search word = EAST`	true
`Q E A D R B T G J I W Z S L N X V M E U C J O P T search word = TEST`	true
`Q E A R M N X Y T search word = ANT`	true
`Q E N R M E X Y T search word = TEN`	true
`Q E A D M B T G E I W Z R L N X I M E U T J O P T search word = MERIT`	true
`Q E A D N B T G A I W Z V L N X A M E U R J O P T search word = RAVAN`	true
