Answer 1

Required Answer:-

Given Information:

• char X = 'A', y = 'a' and z = 'B'

Given to find:

• The value of N.

Solution:

Question 1.

GIVEN,

char N =( X > Y) ? X : Y;

Note:- ASCII Value of 'A' is 65 and that of 'a' 97

So, X > Y is false as 65 > 97 is false.

Therefore,

char N = Y

➡ N = 'a' which is our required answer.

Question 2.

GIVEN,

char N = ( X < Z ) ? ++X : ++Z;

Note:- ASCII value of 'A' is 65 and 'B' is 66.

So, X < Y is true as 65 < 66 is true.

Therefore,

char N = ++Z

➡ char N = 'C' (++Z = Character with ASCII value 67(66+1))

Hence,

char n = 'C' which is our required answer.

Question 3.

GIVEN,

boolean N = ( X == 'A') || (X == 'a') ? true : false;

Here, X == 'A' is true but X == 'a' is false.

As, any one of the conditions is satisfied. So,

➡ boolean N = true which is our required answer.

Question 4.

GIVEN,

int N = ( Y >= X ) ? Y : X;

Note:- ASCII value of 'a' is 97 and that of 'A' is 65

So, Y >= X is true.

So,

int n = Y

➡ int n = (ASCII value of 'a')

➡ int n = 97 which is our required answer.

Answer 2

Explanation:

conditionAn expression whose value is used as a condition.exprIfTrueAn expression which is evaluated if the condition evaluates to a truthy value (one which equals or can be converted to true).exprIfFalseAn expression which is executed if the condition is falsy (that is, has a value which can be converted to false).
